Intel Gaudi support

dstack now supports Intel Gaudi AI accelerators with SSH fleets. To use them with dstack first create an SSH fleet as usual* and then specify either accelerator name (i.e., Gaudi, Gaudi2, Gaudi3) or intel vendor in the run configuration:

type: dev-environment

python: "3.12"
ide: vscode

resources:
  gpu: gaudi2:8  # 8 × Gaudi 2

(*) Gaudi software and drivers should be already installed on the host, including drivers, hl-smi utility and Habana Container Runtime.

Fleets and Instances UI

The UI has been updated for easier fleet and instance management. The Fleets page now allows terminating fleets and can display both active and terminated fleets. The new Instances page displays active and terminated instances across all fleets.

instances

Improved volume detachment

dstack users perviously reported cases when volumes were stuck in detaching state in AWS, and only manual forced detach allowed reusing the volumes. dstack now guarantees that the volumes are detached after the run terminates. If volumes stuck detaching, dstack automatically force detaches them after stop_duration (5 minutes by default). It also force detaches the volumes when you abort the run. You can also set stop_duration: off to turn off force detach and wait for soft detach indefinitely.

Note: Force detaching a volume is a last resort measure and may corrupt the file system. Contact your cloud support if you're experience volumes stuck in the detaching state.

We also fixed a number of bugs that could lead to dstack thinking a volume is attached to the instance even after it was successfully detached in the cloud.

Vultr

Cluster placement

The vultr backend can now provision fleets with cluster placement.

type: fleet

nodes: 4
placement: cluster

resources:
  gpu: 8:MI300X

backends: [vultr]

Nodes in such a cluster will be interconnected and can be used to run distributed tasks.

Performance

The update optimizes the performance of dstack server, allowing a single server replica to handle up to 150 active runs, jobs, and instances. Capacity can be further increased by using PostgreSQL and running multiple server replicas.

Last, getting instance offers from backends when you run dstack apply has also been optimized and now takes less time.

See the documentation for instructions on configuring Vultr in your project.

Vast.ai

Previously, the vastai backend only allowed using Docker images where root is the default user. This limitation has been removed, so you can now run NVIDIA NIM or any other image regardless of the user.

Backward compatibility

If you are going to configure the vultr backend, make sure you update all your dstack CLI and API clients to the latest version. Clients prior to 0.18.35 will not work when Vultr is configured.

Idle duration

If provisioned fleet instances aren’t used, they are marked as idle for reuse within the configured idle duration. After this period, instances are automatically deleted. This behavior was previously configured using the termination_policy and termination_idle_time properties in run or fleet configurations.

With this update, we replace these two properties with idle_duration, a simpler way to configure this behavior. This property can be set to a specific duration or to off for unlimited time.

type: dev-environment
name: vscode

python: "3.11"
ide: vscode

# Terminate instances idle for more than 1 hour
idle_duration: 1h

resources:
  gpu: 24GB

Docker

Previously, dstack had limitations on Docker images for dev environments, tasks, and services. These have now been lifted, allowing images based on various Linux distributions like Alpine, Rocky Linux, and Fedora.

dstack now also supports Docker images with built-in OpenSSH servers, which previously caused issues.

Documentation

The documentation has been significantly improved:

  • Backend configuration has been moved from the Reference page to Concepts→Backends.
  • Major examples related to dev environments, tasks, and services have been relocated from the Reference page to their respective Concepts pages.

Deprecations

  • The termination_idle_time and termination_policy parameters in run configurations have been deprecated in favor of idle_duration.

TPU

Trillium (v6e)

dstack adds support for the latest Trillium TPU (v6e), which became generally available in GCP on December 12th. The new TPU generation doubles the TPU memory and bursts performance, supporting larger workloads.

Resources

dstack now includes CPU, RAM, and TPU memory in Google Cloud TPU offers:

$ dstack apply --gpu tpu

 #  BACKEND  REGION        INSTANCE     RESOURCES                                           SPOT  PRICE

 2  gcp      europe-west4  v6e-1        44xCPU, 176GB, 1xv6e-1 (32GB), 100.0GB (disk)       no    $2.97   
 3  gcp      europe-west4  v2-8         96xCPU, 334GB, 1xv2-8 (64GB), 100.0GB (disk)        no    $4.95

Volumes

By default, TPU VMs contain a 100GB boot disk, and its size cannot be changed. Now, you can add more storage using Volumes.

Gateways

In this update, we've greatly refactored Gateways, improving their reliability and fixing several bugs.

Warning

If you are running multiple replicas of the dstack server, ensure all replicas are upgraded promptly. Leaving some replicas on an older version may prevent them from creating or deleting services and could result in minor errors in their logs.

Assigning service account to GCP VMs

Like all major clouds, GCP supports running a VM on behalf of a managed identity using a service account. Now you can assign a service account to a GCP VM with dstack by specifying the vm_service_account property in the GCP config:

type: gcp
project_id: myproject
vm_service_account: [email protected]
creds:
  type: default

Assigning a service account to a VM can be used to access GCP resources from within runs. Another use case is using firewall rules that rely on the service account as the target. Such rules are typical for Shared VPC setups when admins of a host project can create firewall rules for service projects based on their service accounts.

$HOME improvements

Following support for non-root users in Docker images, dstack improves handling of users' home directories. Most importantly, the HOME environment variable is set according to /etc/passwd, and the home directory is created automatically if it does not exist.

The update opens up new possibilities including the use of an empty volume for /home:

type: dev-environment
ide: vscode
image: ubuntu
user: ubuntu
volumes:
  - volume-aws:/home

AWS Volumes with non-Nitro instances

dstack users previously reported AWS Volumes not working with some instance types. This is now fixed and tested for all instance types supported by dstack including older Xen-based instances like the P3 family.

Deprecations

  • The home_dir and setup parameters in run configurations have been deprecated. If you're using setup, move setup commands to the top of init.

AWS Capacity Reservations and Capacity Blocks

dstack now allows provisioning AWS instances using Capacity Reservations and Capacity Blocks. Given a CapacityReservationId, you can specify it in a fleet or a run configuration:

type: fleet
nodes: 1
name: my-cr-fleet
reservation: cr-0f45ab39cd64a1cee

The instance will use the reserved capacity, so as long as you have enough, the provisioning is guaranteed to succeed.

Non-root users in Docker images

Previously, dstack always executed the workload as root, ignoring the user property set in the image. Now, dstack executes the workload with the default image user, and you can override it with a new user property:

type: task
image: nvcr.io/nim/meta/llama-3.1-8b-instruct
user: nim

The format of the user property is the same as Docker uses: username[:groupname], uid[:gid], and so on.

Improved dstack apply and repos UX

Previously, dstack apply used the current directory as the repo that's made available within the run at /workflow. The directory had to be initialized with dstack init before running dstack apply.

Now you can pass --repo to dstack apply. It can be a path to a local directory or a remote Git repo URL. The specified repo will be available within the run at /workflow. You can also specify --no-repo if the run doesn't need any repo. With --repo or --no-repo specified, you don't need to run dstack init:

$ dstack apply -f task.dstack.yaml --repo .
$ dstack apply -f task.dstack.yaml --repo ../parent_dir
$ dstack apply -f task.dstack.yaml --repo https://github.com/dstackai/dstack.git
$ dstack apply -f task.dstack.yaml --no-repo

Specifying --repo explicitly can be useful when running dstack apply from scripts, pipelines, or CI. dstack init stays relevant for use cases when you work with dstack apply interactively and want to set up the repo to work with once.

Lightweight pip install dstack

pip install dstack used to install all the dstack server dependencies. Now pip install dstack installs only the CLI and Python API, which is optimal for use cases when a remote dstack server is used. You can do pip install "dstack[server]" to install the server or do pip install "dstack[all]" to install the server with all backends supported.

Breaking changes

  • pip install dstack no longer install the server dependencies. If you relied on it to install the server, ensure you use pip install "dstack[server]" or pip install "dstack[all]".

Support internal_ip for SSH fleet clusters

It's now possible to specify instance IP addresses used for communication inside SSH fleet clusters using the internal_ip property:

type: fleet
name: my-ssh-fleet
placement: cluster
ssh_config:
  user: ubuntu
  identity_file: ~/.ssh/dstack/key.pem
  hosts:
    - hostname: "3.79.203.200"
      internal_ip: "172.17.0.1"
    - hostname: "18.184.67.100"
      internal_ip: "172.18.0.2"

If internal_ip is not specified, dstack automatically detects internal IPs by inspecting network interfaces. This works when all instances have IPs belonging to the same subnet and are accessible on those IPs. The explicitly specified internal_ip enables networking configurations when the instances are accessible on IPs that do not belong to the same subnet.

UX enhancements for dstack apply

The dstack apply command gets many improvements including more concise and consistent output and better error reporting. When applying run configurations, dstack apply now prints a table similar to the dstack ps output:

✗ dstack apply
 Project                main                                 
 User                   admin
