For AWS, this must be set to aws. # scale up the cluster in chunks of upscaling_speed*currently_running_nodes. Ray by default detects available resources. # Additional options can be found in the boto docs, e.g. If configured, the key must be added to the project-wide metadata and KeyName has to be defined in the node configuration. sudo kill -9 `sudo lsof /var/lib/dpkg/lock-frontend | awk '{print $2}' | tail -n 1`; git clone https://github.com/aws/efs-utils; sudo apt-get -y install ./build/amazon-efs-utils*deb; sudo mount -t efs {{FileSystemId}}:/ efs; # out the command that can be used to get a remote shell into the head node. ... Config Files. For GCP, this must be set to gcp. use GPU or larger compute instance by editing the yaml file. Configuring Ray¶ Cluster Resources ¶. The user is responsible for properly setting up and cleaning up unmanaged nodes. You can easily config how your jobs are executed by changing ray launcher's configuration here ~/hydra/plugins/hydra_ray_launcher/hydra_plugins/hydra_ray_launcher/conf/hydra/launcher/ray.yaml. The configuration to be used to launch the nodes on the cloud service provider. You may also need to set correct SecurityGroupIds for the instances in the config file. # If True, prevents autoscaling config sync to … # below with a git checkout (and possibly a recompile). # You can change this to latest-cpu if you don't need GPU support and want a faster startup, # image: rayproject/ray:latest-gpu # use this one if you don't need ML dependencies, it's faster to pull, # If true, pulls latest version of image. See theConfigurationdocumentation for the various ways to configure Ray. The cloud service provider. For example, if .gitignore is provided. For example, if set to 1.0, the cluster can grow in size by at most 100% at any time, so if the cluster currently has 20 nodes, at most 20 pending launches are allowed. Takes precedence over minWorkers. Comment this out to use on-demand. (See the “Licensing Requirements for ASA Clustering” section on page 8-27 for the number of units supported per model). # The node config specifies the launch config and physical instance type. In some cases, adding special nodes without any resources may be desirable. To act as a cluster, the ASAs need the following infrastructure: † Isolated, high-speed backplane network for intra-cluster communication, known as the cluster This requires that you have added the key into the, # Provider-specific config for the head node, e.g. Home ; Clusters ; Dashboards ; Blueprints ; ZTKA ; Workloads ; Documentation . Authentication credentials that Ray will use to launch nodes. intermediate_score = objective (step, alpha, beta) # Feed the score back back to Tune. config.ini contains a description of each node involved in the cluster. When cluster resource usage exceeds a configurable threshold (80% by default), new nodes will be launched up to the specified max_workers limit (specified in the cluster config). available_node_types: # List images https://docs.microsoft.com/en-us/azure/virtual-machines/linux/cli-ps-findimage, # optionally set priority to use Spot instances, # set a maximum price for spot instances if desired, echo 'eval "$(conda shell.bash hook)"' >> ~/.bashrc, echo 'conda activate py37_tensorflow' >> ~/.bashrc, pip install -U "ray[default] @ https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp37-cp37m-manylinux2014_x86_64.whl", pip install azure-cli-core==2.22.0 azure-mgmt-compute==14.0.0 azure-mgmt-msi==1.0.0 azure-mgmt-network==10.2.0, # configurations below. The nodes types objectâs keys represent the names of the different node types. A list of commands to run to set up nodes. Most settings can be changed on a running cluster using the Cluster update settings API. The name to use when starting the Docker container. The globally unique project ID to use for deployment of the Ray cluster. # The resources provided by this node type. Config files locationedit # The node type's CPU and GPU resources are auto-detected based on AWS instance type. Local Deployment. To configure an IDM instance as a part of a clustered deployment, follow these steps: Shut down the server if it is running. Cluster — Working directly within or alongside a Spark cluster (standalone, YARN, Mesos, etc.) If you would like to use Ray Tune in your Kubernetes cluster, have a look at this short guide to make it work. It was originally designed to work with multiple nodes that make up a HPC (High Performance Computing) cluster. These commands will be merged with the general setup commands. def objective ( step, alpha, beta): return ( 0.1 + alpha * step / 100) ** ( -1) + beta * 0.1. def training_function ( config): # Hyperparameters. After running the coordinator server it will print the address of the coordinator server. Stopped nodes launch faster than terminated nodes. This server also makes sure to isolate the resources between different users. Here is an example cluster configuration file: Most of the example YAML file is optional. If not configured, Ray will create a new private keypair (default behavior). The path to the kubeconfig file can be overridden using the --kubeconfig flag.. Other flags that can change how the kubeconfig file is written: A list of patterns for files to exclude when running rsync up or rsync down. # The following line demonstrate that you can specify arbitrary, curl -fsSL https://get.docker.com -o get-docker.sh, older Ray versions may need 1+ GPU workers (#2106), Ray Serve: Scalable and Programmable Serving, RLlib Models, Preprocessors, and Action Distributions, ray/python/ray/autoscaler/aws/example-full.yaml, ray/python/ray/autoscaler/azure/example-full.yaml, ray/python/ray/autoscaler/gcp/example-full.yaml, ray/python/ray/autoscaler/kubernetes/example-full.yaml, ray/python/ray/autoscaler/kubernetes/example-ingress.yaml, ray/python/ray/autoscaler/local/example-full.yaml, ray/python/ray/autoscaler/local/coordinator_server.py. # This behavior is a subset of the file_mounts behavior. git clone foo can be rewritten as test -e foo || git clone foo which checks if the repo is already cloned first. Once the Azure CLI is configured to manage resources on your Azure account, you should be ready to launch your cluster. Note that these instructions only work if you are using the AWS Autoscaler. The path to an existing public key for Ray to use. This takes precedence over minimum workers. # List of shell commands to run to set up nodes. from ray import tune def objective (step, alpha, beta): return (0.1 + alpha * step / 100) ** (-1) + beta * 0.1 def training_function (config): # Hyperparameters alpha, beta = config ["alpha"], config ["beta"] for step in range (10): # Iterative training function - can be any arbitrary training procedure. You can specify the external node provider using the yaml config: The module needs to be in the format package.provider_class or package.sub_package.provider_class. To avoid getting the password prompt when running private clusters make sure to setup your ssh keys on the private cluster as follows: You can get started by filling out the fields in the provided ray/python/ray/autoscaler/local/example-full.yaml. If not provided, Autoscaler can automatically detect them only for AWS/Kubernetes cloud providers. rayproject/ray:latest-gpu: CUDA support, no ML dependencies. To use Amazon EFS, install some utilities and mount the EFS in setup_commands. First, install boto (pip install boto3) and configure your AWS credentials in ~/.aws/credentials, Note that youâll need to fill in your resource group and location in those templates. You can also request spot workers for additional cost savings. * wildcard when you are submitting jobs. The repository includes following images: rayproject/ray-ml:latest-gpu: CUDA support, includes ML dependencies. The cluster launcher can also be used to start Ray clusters on an existing Kubernetes cluster. If enabled, nodes will be stopped when the cluster scales down. This is the namespace of the cluster. the Ray autoscaler. # This takes precedence over min_workers. The provided ray/python/ray/autoscaler/gcp/example-full.yaml cluster config file will create a small cluster with a n1-standard-2 head node (on-demand) configured to autoscale up to two n1-standard-2 preemptible workers. # "/path1/on/remote/machine": "/path1/on/local/machine". Once the cluster configuration is defined, you will need to use the Ray CLI to perform any operations such as starting and stopping the cluster. If docker is, # enabled, these commands will run outside the container and before docker. First, install the Azure CLI (pip install azure-cli azure-core) then login using (az login). On cloud providers, nodes will be launched into their own security group by default, with traffic allowed only between nodes in the same group. This section provides instructions for configuring the Ray Cluster Launcher to use with AWS/Azure/GCP, an existing Kubernetes cluster, or on a private cluster of host machines. # A unique identifier for the head node and workers of this cluster. The Autoscaler will not attempt to start, stop, or update unmanaged nodes. © Copyright 2021, The Ray Team. The resources that a node type provides, which enables the autoscaler to automatically select the right type of nodes to launch given the resource demands of the application. # The maximum number of worker nodes to launch in addition to the head. If enabled, Ray will not automatically specify the size /dev/shm for the started container and the runtimeâs default value (64MiB for Docker) will be used. This section describes the easiest way to launch a Ray cluster on Kubernetes. The example-full.yaml configuration is enough to get started with Ray, but for more compute intensive workloads you will want to change the instance types to e.g. For example, head_node: {InstanceType: c5.xlarge, ImageId: latest_dlami}. If enabled, the latest version of image will be pulled when starting Docker. Cluster SSH (cssh) is a utility that allows you to manage multiple servers over SSH from a single administration console. Commands to start ray on the head node. If disabled, docker run will only pull the image if no cached version is present. Tells the autoscaler the allowed node types and the resources they provide. You don't need to change this. # The key is the name of the node type, which is just for debugging purposes. The cloud service provider. Only use this if you know what you're doing! # List the pods running in the cluster. head_node_type: head_node # Specify the allowed pod types for this ray cluster and the resources they provide. # Files or directories to copy to the head and worker nodes. Autoscaling GPU cluster: similar to the autoscaling CPU cluster, but # The autoscaler will scale up the cluster faster with higher upscaling speed. Alternatively, you can deploy a cluster using Azure portal directly. head_start_ray_commands: - ray stop - ulimit -n 65536; ray start --head --redis-port=6379 --object-manager-port=8076 --autoscaling-config=~/ray_bootstrap_config.yaml # Command to start ray on worker … A list of commands to run to set up the worker nodes. The Ray Cluster Launcher will automatically enable a load-based autoscaler. The same path on the head node will be copied to the worker node. instance type. After the cluster has been created, the appropriate kubernetes configuration will be added to your kubeconfig file. from ray import tune. The key is the name of the node type, which is just for debugging purposes. If not specified, Ray will use the default from the Azure CLI. and opens all the necessary ports to support the Ray cluster. The head node conveniently exposes both SSH as well as JupyterLab. For more information, see also the resource demand scheduler. Cluster YAML Configuration Options The cluster configuration is defined within a YAML file that will be used by the Cluster Launcher to launch the head node, and by the Autoscaler to launch worker nodes. To launch a Ray autoscaled cluster using Amazon Web Service (AWS), you can use the file examples/cluster/aws_example.yaml as the config file when launching an autoscaled Ray cluster. This is, the file that you have configured in the environment variable KUBECONFIG or ~/.kube/config by default. # "/path2/on/remote/machine": "/path2/on/local/machine", # Files or directories to copy from the head node to the worker nodes. Cluster Configuration and config.xml. The cloud service provider. Local mode is an excellent way to learn and experiment with Spark. A list of patterns for files to exclude when running rsync up or rsync down. # dictionary from REMOTE_PATH: LOCAL_PATH, e.g. The extra options to pass to docker run for worker nodes only. This node type will be used to launch the head node. config.ini contains a description of each node involved in the cluster. # no_monitor_on_head is an internal flag used by the Ray K8s operator. Endpoints can register to any of the peers in a cluster. # By default Ray creates a new private keypair, but you can also use your own. # The maximum number of worker nodes of this type to launch. By default. A list of paths to the files or directories to copy from the head node to the worker nodes. There can be only one cluster for each node. The files or directories to copy to the head and worker nodes. # How Ray will authenticate with newly launched nodes. To execute the above Ray script in the cloud, just download this configuration file, and run: ray submit [CLUSTER.YAML] example.py --start. instance type. These commands will be merged with the general setup commands. docker: image: " rayproject/ray-ml:latest-gpu " # You can change this to latest-cpu if you don't need GPU support and want a faster startup # image: rayproject/ray:latest-gpu # use this one if you don't need ML dependencies, it's faster to pull # Empty string means disabled. This will deploy Azure Data Science VMs (DSVM) By The Ray Team Configuring a DMR Cluster. To use a shared subnet, ask the subnet owner to grant permission. You donât need to change this. If Docker is enabled, these commands will run outside the container and before Docker is setup. A cluster is a provisioned object on an event broker that contains global DMR configuration parameters. A YAML object which conforms to the EC2 create_instances API in the AWS docs. Setting this property allows propagation of a default value to all the node types when they launch as workers (e.g., using spot instances across all workers can be configured here so that it doesnât have to be set across all instance types). See this blog post for a step by step guide to using the Ray Cluster Launcher. # This executes all commands on all nodes in the docker container. Docker image for the worker nodes to override the default docker image. See this blog post for a step by step guide to using the Ray Cluster Launcher. This behavior is a subset of the file_mounts behavior, so in the vast majority of cases one should just use file_mounts. Once the API client is configured to manage resources on your GCP account, you should be ready to launch your cluster. Be sure to specify the proper head_ip, list of worker_ips, and the ssh_user field. config.ini: This file, sometimes known as the global configuration file, is read only by the NDB Cluster management server, which then distributes the information contained therein to all processes participating in the cluster. Generally, node configs are set in the node config of each node type. The most preferable way to run a Ray cluster on a private cluster of hosts is via the Ray Cluster Launcher. # Tell the autoscaler the allowed node types and the resources they provide. By default, the number of workers of a node type is unbounded, constrained only by the cluster-wide max_workers. Once the cluster configuration is defined, you will need to use the Ray CLI to perform any operations such as starting and stopping the cluster. Otherwise, `docker run` will only pull the image, # Extra options to pass into "docker run", # Example of running a GPU head with CPU workers, # head_image: "rayproject/ray-ml:latest-gpu", # worker_image: "rayproject/ray-ml:latest-cpu". # https://azure.microsoft.com/en-us/global-infrastructure/locations, # set subscription id otherwise the default from az cli will be used, # subscription_id: 00000000-0000-0000-0000-000000000000, # More specific customization to node configurations can be made using the ARM template azure-vm-template.json file, # See documentation here: https://docs.microsoft.com/en-us/azure/templates/microsoft.compute/2019-03-01/virtualmachines, # Changes to the local file will be used during deployment of the head node, however worker nodes deployment occurs, # on the head node, so changes to the template must be included in the wheel file used in setup_commands section below. # Try running a Ray program with 'ray.init(address="auto")'. # Provider-specific config, e.g. # Nodes are currently spread between zones by a round-robin approach. After you have customized the nodes, it is also a good idea to create a new machine image (or docker container) and use that in the config file. In our example configuration file, the head node is a CPU-only machine, and the workers all have GPUs. run (training_function, config … The path to an existing private key for Ray to use. # Specify the pod type for the ray head node (as configured below). Parameters configured at the cluster level apply to all links in the cluster, unless you override each setting by providing equivalent cluster link-level configuration. The provided ray/python/ray/autoscaler/kubernetes/example-full.yaml cluster config file will create a small cluster of one pod for the head node configured to autoscale up to two worker node pods, with all pods requiring 1 CPU and 0.5GiB of memory. The cluster consists of multiple ASAs acting as a single unit. # Specify the node type of the head node (as configured above). # If desired, you can override the autodetected CPU and GPU resources advertised to the autoscaler. A list of commands that will be run before the setup commands. bursty workloads. ray launcher lets you launch application on your ray cluster or local machine. The key for one of the node types in available_node_types. Start by launching the coordinator server that will manage all the on prem clusters. Remove the local unit from the cluster. If not running cluster mode, you can specify cluster... Logging and Debugging ¶. The Ray Cluster Launcher requires a cluster configuration file, which specifies some important details about the cluster. Automatically managed, i.e., the user only specifies a coordinator address to a coordinating server that automatically coordinates its head and worker ips. # Whether changes to directories in file_mounts or cluster_synced_files in the head node, # should sync to the worker node continuously, # Patterns for files to exclude when running rsync up or rsync down, # Pattern files to use for filtering out files when running rsync up or rsync down. The configuration files should contain settings which are node-specific (such as node.name and paths), or settings which a node requires in order to be able to join a cluster, such as cluster.name and network.host. The maximum number of workers the cluster will have at any given time. The script for running the coordinator server is ray/python/ray/autoscaler/local/coordinator_server.py. component: example-cluster-ray-head: ports: - name: client: protocol: TCP: port: 10001: targetPort: 10001 - name: dashboard: protocol: TCP: port: 8265: targetPort: 8265 # Specify the pod type for the ray head node (as configured below). Once you have kubectl configured locally to access the remote cluster, you should be ready to launch your cluster. The filter is applied on the source directory and recursively through all subdirectories. pip install google-api-python-client==1.7.8, --autoscaling-config=~/ray_bootstrap_config.yaml, Asynchronous Advantage Actor Critic (A3C), Ray Serve: Scalable and Programmable Serving, Model selection and serving with Ray Tune and Ray Serve, External library integrations (tune.integration), RLlib Models, Preprocessors, and Action Distributions, RLlib Sample Collection and Trajectory Views. config.ini: This file, sometimes known as the global configuration file, is read only by the NDB Cluster management server, which then distributes the information contained therein to all processes participating in the cluster. The number of GPUs made available by this node. # Command to start ray on the head node. (Prior to Ray 1.3.0, the default value for this field was 0.). Here are a few common configurations: GPU single node: use Ray on a single large GPU instance. CPU than GPU resources, you can use additional CPU workers with a GPU head node. # and opens all the necessary ports to support the Ray cluster. When the command finishes, it will print. # For more documentation on available fields, see: # http://boto3.readthedocs.io/en/latest/reference/services/ec2.html#EC2.ServiceResource.create_instances, # You can provision additional disk space with a conf as follows. The cluster config is a JSON- or YAML-formatted file that contains objects that match names of rules in the Snakefile. # The minimum number of worker nodes of this type to launch. podTypes: - name: head-node # Minimum number of Ray workers of this Pod type. # and opens all the necessary ports to support the Ray cluster. Ideally, you should avoid using setup_commands by creating a docker image with all the dependencies preinstalled to minimize startup time. The provided ray/python/ray/autoscaler/azure/example-full.yaml cluster config file will create a small cluster with a Standard DS2v3 head node (on-demand) configured to autoscale up to two Standard DS2v3 spot workers. Mixed GPU and CPU nodes: for RL applications that require proportionally more You shoud only see one head node, # until you start running an application, at which point worker nodes, # should be started. You may use ssh-keygen -t rsa -b 4096 to generate a new ssh keypair. The number of CPUs made available by this node. The format is a. tune. minWorkers: 0 # Maximum number of Ray workers of this Pod type. Deploying Ray on a cluster requires a bit of manual work. # If a node is idle for this many minutes, it will be removed. First, install the Google API client (pip install google-api-python-client), set up your GCP credentials, and create a new GCP project. # Ray will auto-configure unspecified fields such as SubnetId and KeyName. The example application starts a new ray cluster. Otherwise an existing subnet is, # used. alpha, beta = config [ "alpha"], config [ "beta"] for step in range ( 10): # Iterative training function - can be any arbitrary training procedure. headPodType: head-node # Specify the allowed pod types for this ray cluster and the resources they provide. Ports configurations ¶. workers as needed. If set to False, nodes will be terminated. Docker: Specify docker image. The default Docker image to pull in the head and worker nodes. To launch the coordinator server run: where list_of_node_ips is a comma separated list of all the available nodes on the private cluster. # List of commands that will be run before `setup_commands`. Test that it works by running the following commands from your local machine: For the AWS node configuration, you can set "ImageId: latest_dlami" to automatically use the newest Deep Learning AMI for your region. For example: Next, the user only specifies the printed above in the coordinator_address entry instead of specific head/worker ips in the provided ray/python/ray/autoscaler/local/example-full.yaml. for both the head node and the auto-scalable cluster managed by Azure Virtual Machine Scale Sets. # To run the nightly version of ray (as opposed to the latest), either use a rayproject docker image. Configuring your Cluster¶ The Ray Cluster Launcher requires a cluster configuration file, which specifies some important details about the cluster. The Domain element is the top-level element, and all elements in the Domain descend from the Domain element. # for 'compute.subnetworks.use' to the ray autoscaler account... # Run workers on preemtible instance by default. In rare cases when Docker is not available on the system by default (e.g., bad AMI), add the following commands to initialization_commands to install it. Now we cant test that it works by running the following commands from your local machine: Ray also supports external node providers (check node_provider.py implementation). Expressway clusters are designed to extend the resilience and capacity of an Expressway installation. For example, if you are using anaconda, you need to run conda activate env && pip install -U ray because splitting the command into two setup commands will not work. A lot of ray commands require a CLUSTER_CONFIG file. # Availability zone(s), comma-separated, that nodes may be launched in. A list of commands to run to set up worker nodes of this type. Such nodes can be used as a driver which connects to the cluster to launch jobs. # however this implementation detail should not be relied upon. Example for a pattern in the list: **/.git/**. Setup commands should ideally be idempotent (i.e., can be run multiple times without changing the result); this allows Ray to safely update nodes after they have been created. A YAML object as defined in the deployment template whose resources are defined in the Azure docs. A set of overrides to the top-level Docker configuration. Once boto is configured to manage resources on your AWS account, you should be ready to launch your cluster. This does not remove the cluster config: ASA-1(config)# cluster group TwoNodeCluster ASA-1(cfg-cluster)# no enable Cluster disable is performing cleanup..done. For example, 160.24.42.48,160.24.42.49,... and is the port that the coordinator server will listen on. To check if Ray is initialized, you can call ray.is_initialized(). There are two ways of running private clusters: Manually managed, i.e., the user explicitly specifies the head and worker ips. If --shm-size=<> is manually added to run_options, this is automatically set to True, meaning that Ray will defer to the user-provided value. The configuration to be used to launch worker nodes on the cloud service provider. The user that Ray will authenticate with when launching new nodes. If enabled, Ray will not try to use the NVIDIA Container Runtime if GPUs are present. The path to an existing private key for Ray to use. fully compatible with deep learning frameworks like TensorFlow, PyTorch, and MXNet, and it is natural to use one or more deep learning frameworks along with Ray in many applications (for Then, you can replace the pip installs. report (mean_loss = intermediate_score) analysis = tune. You can usually make commands idempotent with small modifications, e.g. Expressway peers in a cluster share bandwidth usage as well as routing, zone, FindMe™ and other configuration. # Create or update the cluster. for example Usage: ray get-head-ip [OPTIONS] CLUSTER_CONFIG_FILE Options: -n, --cluster-name TEXT Override the configured cluster name. At a minimum, we need to specify: Among other things, this will specify the instance type to be launched. docker.disable_automatic_runtime_detection, available_node_types..node_type.node_config, available_node_types..node_type.resources, available_node_types..node_type.min_workers, available_node_types..node_type.max_workers, available_node_types..node_type.worker_setup_commands, available_node_types..node_type.resources.CPU, available_node_types..node_type.resources.GPU, available_node_types..docker, curl -fsSL https://get.docker.com -o get-docker.sh, echo 'export PATH="$HOME/anaconda3/envs/tensorflow_p36/bin:$PATH"' >> ~/.bashrc, pip install -U https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp36-cp36m-manylinux2014_x86_64.whl, ulimit -n 65536; ray start --head --port=6379 --object-manager-port=8076 --autoscaling-config=~/ray_bootstrap_config.yaml, ulimit -n 65536; ray start --address=$RAY_HEAD_IP:6379 --object-manager-port=8076. The name of the cluster. .. _cluster-config: Cluster YAML Configuration Options ===== The cluster configuration is defined within a YAML file that will be used by the Cluster Launcher to launch the head node, and by the Autoscaler to launch worker nodes. These commands will replace the general worker setup commands for the node. Note that youâll need to fill in your project id in those templates. This allows Ray to update nodes after they have been created. rayproject/ray-ml:latest: No CUDA support, includes ML dependencies. Each Ray session will have a unique name. The same path on the head node will be copied to the worker node. The number of nodes allowed to be pending as a multiple of the current number of nodes.
