Create AI-optimized instances in bulk with A3 High or A3 Mega

This document explains how to create virtual machine (VM) instances in bulk that use A3 High or A3 Mega accelerator-optimized machine types. To learn more about the machine types, see A3 High and A3 Mega in the Compute Engine documentation.

For more information about creating VMs in bulk, see About bulk creation of VMs in the Compute Engine documentation.

To learn about other ways to create VMs or clusters, see the Overview page.

Before you begin

Before creating VMs in bulk, if you haven't already done so, complete the following steps:

1. Choose a consumption option: your choice of consumption option determines how you get and use GPU resources.

   To learn more, see Choose a consumption option.

2. Obtain capacity: the process to obtain capacity differs for each consumption option.

   To learn about the process to obtain capacity for your chosen consumption option, see Capacity overview.

Select the tab for how you plan to use the samples on this page:

Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

gcloud

In the Google Cloud console, activate Cloud Shell.

Activate Cloud Shell

At the bottom of the Google Cloud console, a Cloud Shell session starts and displays a command-line prompt. Cloud Shell is a shell environment with the Google Cloud CLI already installed and with values already set for your current project. It can take a few seconds for the session to initialize.

REST

To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:

gcloud init

If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

Required roles

To get the permissions that you need to create VMs in bulk, ask your administrator to grant you the Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) IAM role on the project. For more information about granting roles, see Manage access to projects, folders, and organizations.

This predefined role contains the permissions required to create VMs in bulk. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

The following permissions are required to create VMs in bulk:

• compute.instances.create on the project
• To use a custom image to create the VM: compute.images.useReadOnly on the image
• To use a snapshot to create the VM: compute.snapshots.useReadOnly on the snapshot
• To use an instance template to create the VM: compute.instanceTemplates.useReadOnly on the instance template
• To specify a subnet for your VM: compute.subnetworks.use on the project or on the chosen subnet
• To specify a static IP address for the VM: compute.addresses.use on the project
• To assign an external IP address to the VM when using a VPC network: compute.subnetworks.useExternalIp on the project or on the chosen subnet
• To assign a legacy network to the VM: compute.networks.use on the project
• To assign an external IP address to the VM when using a legacy network: compute.networks.useExternalIp on the project
• To set VM instance metadata for the VM: compute.instances.setMetadata on the project
• To set tags for the VM: compute.instances.setTags on the VM
• To set labels for the VM: compute.instances.setLabels on the VM
• To set a service account for the VM to use: compute.instances.setServiceAccount on the VM
• To create a new disk for the VM: compute.disks.create on the project
• To attach an existing disk in read-only or read-write mode: compute.disks.use on the disk
• To attach an existing disk in read-only mode: compute.disks.useReadOnly on the disk

You might also be able to get these permissions with custom roles or other predefined roles.

Overview

Creating instances in bulk with the a3h-or-a3m machine type includes the following steps:

1. Create VPC networks
2. Optional: Create a compact placement policy
3. Create instances in bulk

Create VPC networks

To enable efficient communication for your GPU VMs, you need to create a management network and one or more data networks. The management network is used for external access, for example SSH, and for most general network communication. The data networks are used for high-performance communication between the GPUs on different VMs, for example, for Remote Direct Memory Access (RDMA) traffic.

For these VPC networks, we recommend setting the maximum transmission unit (MTU) to a larger value. Higher MTU values increase the packet size and reduce the packet-header overhead, which increases payload data throughput. For more information about how to create VPC networks, see Create and verify a jumbo frame MTU network.

Create management network, subnet, and firewall rule

Complete the following steps to set up the management network:

1. Create the management network by using the networks create command:

   gcloud compute networks create NETWORK_NAME_PREFIX-mgmt-net \
       --project=PROJECT_ID \
       --subnet-mode=custom \
       --mtu=8244
   

2. Create the management subnet by using the networks subnets create command:

   gcloud compute networks subnets create NETWORK_NAME_PREFIX-mgmt-sub \
       --project=PROJECT_ID \
       --network=NETWORK_NAME_PREFIX-mgmt-net \
       --region=REGION \
       --range=192.168.0.0/24
   

3. Create firewall rules by using the firewall-rules create command.

   1. Create a firewall rule for the management network.

      gcloud compute firewall-rules create NETWORK_NAME_PREFIX-mgmt-internal \
          --project=PROJECT_ID \
          --network=NETWORK_NAME_PREFIX-mgmt-net \
          --action=ALLOW \
          --rules=tcp:0-65535,udp:0-65535,icmp \
          --source-ranges=192.168.0.0/16
      

   2. Create the tcp:22 firewall rule to limit which source IP addresses can connect to your VM by using SSH.

      gcloud compute firewall-rules create NETWORK_NAME_PREFIX-mgmt-external-ssh \
          --project=PROJECT_ID \
          --network=NETWORK_NAME_PREFIX-mgmt-net \
          --action=ALLOW \
          --rules=tcp:22 \
          --source-ranges=SSH_SOURCE_IP_RANGE
      

   3. Create the icmp firewall rule that can be used to check for data transmission issues in the network.

      gcloud compute firewall-rules create NETWORK_NAME_PREFIX-mgmt-external-ping \
          --project=PROJECT_ID \
          --network=NETWORK_NAME_PREFIX-mgmt-net \
          --action=ALLOW \
          --rules=icmp \
          --source-ranges=0.0.0.0/0
      

Replace the following:

• NETWORK_NAME_PREFIX: the name prefix to use for the VPC networks and subnets.
• PROJECT_ID : your project ID.
• REGION: the region where you want to create the networks.
• SSH_SOURCE_IP_RANGE: IP range in CIDR format. This specifies which source IP addresses can connect to your VM by using SSH.

Create data networks, subnets, and firewall rule

The number of data networks varies depending on the type of GPU machine you are creating.

A3 Mega

A3 Mega requires eight data networks. To create eight data networks, each with subnets and firewall rules, use the following command.

for N in $(seq 1 8); do
gcloud compute networks create NETWORK_NAME_PREFIX-data-net-$N \
    --project=PROJECT_ID \
    --subnet-mode=custom \
    --mtu=8244

gcloud compute networks subnets create NETWORK_NAME_PREFIX-data-sub-$N \
    --project=PROJECT_ID \
    --network=NETWORK_NAME_PREFIX-data-net-$N \
    --region=REGION \
    --range=192.168.$N.0/24

gcloud compute firewall-rules create NETWORK_NAME_PREFIX-data-internal-$N \
    --project=PROJECT_ID \
    --network=NETWORK_NAME_PREFIX-data-net-$N \
    --action=ALLOW \
    --rules=tcp:0-65535,udp:0-65535,icmp \
    --source-ranges=192.168.0.0/16
done

A3 High

A3 High require four data networks. Use the following command to create four data networks, each with subnets and firewall rules.

for N in $(seq 1 4); do
gcloud compute networks create NETWORK_NAME_PREFIX-data-net-$N \
    --project=PROJECT_ID \
    --subnet-mode=custom \
    --mtu=8244

gcloud compute networks subnets create NETWORK_NAME_PREFIX-data-sub-$N \
    --project=PROJECT_ID \
    --network=NETWORK_NAME_PREFIX-data-net-$N \
    --region=REGION \
    --range=192.168.$N.0/24

gcloud compute firewall-rules create NETWORK_NAME_PREFIX-data-internal-$N \
    --project=PROJECT_ID \
    --network=NETWORK_NAME_PREFIX-data-net-$N \
    --action=ALLOW \
    --rules=tcp:0-65535,udp:0-65535,icmp \
    --source-ranges=192.168.0.0/16
done

Optional: Create a compact placement policy

Tip: To place your VMs in single or adjacent blocks, specify VM placement by creating and applying a placement policy to your VMs. Otherwise, to place VMs on a specific block, skip this step and provide the name of the block when you create VMs.

You can specify VM placement by creating a compact placement policy. When you apply a compact placement policy to your VMs, Compute Engine makes best-effort attempts to create VMs that are as close to each other as possible. If your application is latency-sensitive and you want the VMs to be closer together (maximum compactness), then specify the maxDistance field (Preview) when creating a compact placement policy. A lower maxDistance value ensures closer VM placement, but it also increases the chance that some VMs won't be created.

To create a compact placement policy, select one of the following options:

gcloud

To create a compact placement policy, use the gcloud beta compute resource-policies create group-placement command:

gcloud beta compute resource-policies create group-placement POLICY_NAME \
    --collocation=collocated \
    --max-distance=MAX_DISTANCE \
    --region=REGION

Replace the following:

• POLICY_NAME: the name of the compact placement policy.
• MAX_DISTANCE: the maximum distance configuration for your VMs. The value must be 3 to place VMs in the adjacent blocks, or 2 to place VMs in the same block. For information about the maximum number of VMs supported for each maxDistance per machine series, see About compact placement policies in the Compute Engine documentation.
• REGION: the region where you want to create the compact placement policy. Specify a region in which the machine type that you want to use is available. For information about regions, see GPU availability by regions and zones.

REST

To create a compact placement policy, make a POST request to the beta resourcePolicies.insert method. In the request body, include the collocation field set to COLLOCATED, and the maxDistance field.

POST https://compute.googleapis.com/compute/beta/projects/PROJECT_ID/regions/REGION/resourcePolicies
  {
    "name": "POLICY_NAME",
    "groupPlacementPolicy": {
      "collocation": "COLLOCATED",
      "maxDistance": MAX_DISTANCE
    }
  }

Replace the following:

• PROJECT_ID: your project ID
• POLICY_NAME: the name of the compact placement policy.
• MAX_DISTANCE: the maximum distance configuration for your VMs. The value must be 3 to place VMs in the adjacent blocks, or 2 to place VMs in the same block. For information about the maximum number of VMs supported for each maxDistance per machine series, see About compact placement policies in the Compute Engine documentation.
• REGION: the region where you want to create the compact placement policy. Specify a region in which the machine type that you want to use is available. For information about regions, see GPU availability by regions and zones.

Create A3 High or A3 Mega VMs in bulk

To create A3 High or A3 Mega VMs in bulk, use one of the following methods.

The following commands also set the access scope for your instances. To simplify permissions management, Google recommends that you set the access scope on an instance to cloud-platform access and then use IAM roles to define what services the instance can access. For more information, see Scopes best practice.

gcloud

To create an A3 High or A3 Mega VM, use the gcloud compute instances bulk create command.

A3 Mega

To create VMs in bulk, use the gcloud compute instances bulk create command.

The parameters that you need to specify depend on the consumption option that you are using for this deployment. Select the tab that corresponds to your consumption option's provisioning model.

    --restart-on-failure

Complete the following steps:

1. Replace the following:

   • NAME_PATTERN: the name pattern of the VMs. For example, using vm-# for the name pattern generates VMs with names such as vm-1 and vm-2, up to the number of VMs specified by --count.
   • COUNT: the number of VMs to create.
   • MACHINE_TYPE: the machine type to use for the VM. Specify either an A4 or A3 Ultra machine type. For more information, see GPU machine types.
   • IMAGE_FAMILY: the image family of the OS image that you want to use. For the A3 Mega machine series, we strongly recommend that you either use the cos-121-lts or later Container-Optimized OS image and disable automatic updates or use the rocky-linux-8-optimized-gcp-nvidia-580 Rocky Linux image. For a list of supported operating systems, see Supported operating systems.
   • IMAGE_PROJECT: the project ID of the OS image. For example, use either cos-cloud for the cos-121-lts or later Container-Optimized OS image or use rocky-linux-accelerator-cloud for the rocky-linux-8-optimized-gcp-nvidia-580 Rocky Linux image.
   • REGION: specify a region in which the machine type that you want to use is available. If you want to specify a compact placement policy, then you must use the same region as the compact placement policy. For information about regions, see GPU availability by regions and zones.
   • DISK_TYPE: the type of the boot disk. We recommend that you use hyperdisk-balanced.
   • DISK_SIZE: the size of the boot disk in GB.
   • GVNIC_NAME_PREFIX: the name prefix that you specified when creating the standard VPC networks and subnets that use gVNIC NICs.
   • RESERVATION: either the reservation name or a specific block within a reservation. To get the reservation name or the available blocks, see View reserved capacity. Based on your requirement for instance placement, choose one of the following:

     • To create instances across blocks or on a single block:

       projects/RESERVATION_OWNER_PROJECT_ID/reservations/RESERVATION_NAME

       Additionally, for a single block, apply a compact placement policy that specifies a block collocation (maxDistance=2) . Compute Engine then applies the policy to the reservation and creates instances on the same block.

     • To create instances on a specific block:

       projects/RESERVATION_OWNER_PROJECT_ID/reservations/RESERVATION_NAME/reservationBlocks/RESERVATION_BLOCK_NAME

     Tip: If the reservation exists in the current project, then you can omit projects/RESERVATION_OWNER_PROJECT_ID/reservations/ from the reservation value.

   • TERMINATION_ACTION: whether Compute Engine stops (STOP) or deletes (DELETE) the VM at the end of the reservation period.

2. Optional: If you chose to use a compact placement policy, then add the following flag to the command:

     --resource-policies=POLICY_NAME
   

   Replace the following:

   • POLICY_NAME: the name of the compact placement policy.
3. Run the command.

Complete the following steps:

1. Replace the following:

   • PROJECT_ID: the project ID of the project where you want to create the VM.
   • ZONE: specify a zone in which the machine type that you want to use is available. If you want to specify a compact placement policy, then you must use a zone in the same region as the compact placement policy. For information about regions, see GPU availability by regions and zones.
   • NAME_PATTERN: the name pattern of the VMs. For example, using vm-# for the name pattern generates VMs with names such as vm-1 and vm-2, up to the number of VMs specified by --count.
   • COUNT: the number of VMs to create.
   • MACHINE_TYPE: the machine type to use for the VM. Specify either an A4 or A3 Ultra machine type. For more information, see GPU machine types.
   • VM_NAME: the name of the VM.
   • DISK_SIZE: the size of the boot disk in GB.
   • DISK_TYPE: the type of the boot disk. We recommend that you use hyperdisk-balanced.
   • IMAGE_PROJECT: the project ID of the OS image. For example, use either cos-cloud for the cos-121-lts or later Container-Optimized OS image or use rocky-linux-accelerator-cloud for the rocky-linux-8-optimized-gcp-nvidia-580 Rocky Linux image.
   • IMAGE_FAMILY: the image family of the OS image that you want to use. For the A3 Mega machine series, we strongly recommend that you either use the cos-121-lts or later Container-Optimized OS image and disable automatic updates or use the rocky-linux-8-optimized-gcp-nvidia-580 Rocky Linux image. For a list of supported operating systems, see Supported operating systems.
   • NETWORK_PROJECT_ID: the project ID of the network.
   • GVNIC_NAME_PREFIX: the name prefix that you specified when creating the standard VPC networks and subnets that use gVNIC NICs.
   • REGION: the region of the subnetwork.
   • RESERVATION: either the reservation name or a specific block within a reservation. To get the reservation name or the available blocks, see View reserved capacity. Based on your requirement for instance placement, choose one of the following:

     • To create instances across blocks or on a single block:

       projects/RESERVATION_OWNER_PROJECT_ID/reservations/RESERVATION_NAME

       Additionally, for a single block, apply a compact placement policy that specifies a block collocation (maxDistance=2) . Compute Engine then applies the policy to the reservation and creates instances on the same block.

     • To create instances on a specific block:

       projects/RESERVATION_OWNER_PROJECT_ID/reservations/RESERVATION_NAME/reservationBlocks/RESERVATION_BLOCK_NAME

     Tip: If the reservation exists in the current project, then you can omit projects/RESERVATION_OWNER_PROJECT_ID/reservations/ from the reservation value.

   • TERMINATION_ACTION: whether Compute Engine stops (STOP) or deletes (DELETE) the VM at the end of the reservation period.

2. Optional: If you chose to use a compact placement policy, then add the following instanceProperties subfield to the request body:

       "resourcePolicies": [
         "projects/PROJECT_ID/regions/REGION/resourcePolicies/POLICY_NAME"
       ]
   

   Replace the following:

   • PROJECT_ID: the project ID of the compact placement policy.
   • REGION: the region of the compact placement policy.
   • POLICY_NAME: the name of the compact placement policy.

}

Complete the following steps:

1. Replace the following:

   • PROJECT_ID: the project ID of the project where you want to create the VM.
   • ZONE: specify a zone in which the machine type that you want to use is available. If you want to specify a compact placement policy, then you must use a zone in the same region as the compact placement policy. For information about regions, see GPU availability by regions and zones.
   • NAME_PATTERN: the name pattern of the VMs. For example, using vm-# for the name pattern generates VMs with names such as vm-1 and vm-2, up to the number of VMs specified by --count.
   • COUNT: the number of VMs to create.
   • MACHINE_TYPE: the machine type to use for the VM. Specify either an A4 or A3 Ultra machine type. For more information, see GPU machine types.
   • VM_NAME: the name of the VM.
   • DISK_SIZE: the size of the boot disk in GB.
   • DISK_TYPE: the type of the boot disk. We recommend that you use hyperdisk-balanced.
   • IMAGE_PROJECT: the project ID of the OS image. For example, use cos-cloud for the cos-121-lts or later Container-Optimized OS image.
   • IMAGE_FAMILY: the image family of the OS image that you want to use. For the A3 High machine series, we strongly recommend that you use the cos-121-lts or later Container-Optimized OS image and disable automatic updates. For a list of supported operating systems, see Supported operating systems.
   • NETWORK_PROJECT_ID: the project ID of the network.
   • GVNIC_NAME_PREFIX: the name prefix that you specified when creating the standard VPC networks and subnets that use gVNIC NICs.
   • REGION: the region of the subnetwork.

   • TERMINATION_ACTION: the action to take when Compute Engine preempts the instance, either STOP (default) or DELETE.

     Important: Make sure your application can handle preemption. For example, handle preemption by specifying a shutdown script during instance creation. Learn how to handle preemption with a shutdown script.

2. Optional: If you chose to use a compact placement policy, then add the following instanceProperties subfield to the request body:

       "resourcePolicies": [
         "projects/PROJECT_ID/regions/REGION/resourcePolicies/POLICY_NAME"
       ]
   

   Replace the following:

   • PROJECT_ID: the project ID of the compact placement policy.
   • REGION: the region of the compact placement policy.
   • POLICY_NAME: the name of the compact placement policy.
3. Submit the request.
