Simplified backend integration

To provide best multi-cloud experience and GPU availability, dstack integrates with many cloud GPU providers including AWS, Azure, GCP, RunPod, Lambda, Vultr, and others. As we'd like to see even more GPU providers supported by dstack, this release comes with a major internal refactoring aimed to simplify the process of adding new integrations. See the Backend integration guide for more details. Join our Discord if have any questions about the integration process.

MPI workloads and NCCL tests

dstack now configures internode SSH connectivity for distributed tasks. You can log in to any node from any node via SSH with a simple ssh <node_ip> command. The out-of-the-box SSH connectivity also allows running mpirun. See the NCCL Tests example.

Cost and usage metrics

In addition to DCGM metrics, dstack now exports a set of Prometheus metrics for cost and usage tracking. Here's how it may look in the Grafana dashboard:

See the documentation for a full list of metrics and labels.

Cursor IDE support

dstack can now launch Cursor dev environments. Just specify ide: cursor in the run configuration:

type: dev-environment
ide: cursor

Deprecations

  • The Python API methods get_plan(), exec_plan(), and submit() are deprecated in favor of get_run_plan(), apply_plan(), and apply_configuration(). The deprecated methods had clumsy signatures with many top-level parameters. The new signatures align better with the CLI and HTTP API.

Breaking changes

The 0.19.0 release drops several previously deprecated or undocumented features. There are no other significant breaking changes. The 0.19.0 server continues to support 0.18.x CLI versions. But the 0.19.0 CLI does not work with older 0.18.x servers, so you should update the server first or the server and the clients simultaneously.

  • Drop the dstack run CLI command.
  • Drop the --attach mode for the dstack logs CLI command.
  • Drop Pools functionality:
    • The dstack pool CLI commands.
    • /api/project/{project_name}/runs/get_offers, /api/project/{project_name}/runs/create_instance, /api/pools/list_instances, /api/project/{project_name}/pool/* API endpoints.
    • pool_name and instance_name parameters in profiles and run configurations.
  • Remove retry_policy from profiles.
  • Remove termination_idle_time and termination_policy from profiles and fleet configurations.
  • Drop RUN_NAME and REPO_ID run environment variables.
  • Drop the /api/backends/config_values endpoint used for interactive configuration.
  • The API accepts and returns azure_config["regions"] instead of azure_config["locations"] (unified with server/config.yml).
