Runs

Priorities

Run configurations now support a priority field. This is a new property that accepts a number between 0 and 100. The higher the number, the higher the priority of the run. This influences the order in which runs are provisioned and executed in the queue.

type: task
name: train

# Can be 0–100; higher means higher priority
priority: 50

python: "3.10"

# Commands of the task
commands:
  - pip install -r fine-tuning/qlora/requirements.txt
  - python fine-tuning/qlora/train.py

# Retry policy to queue tasks
retry:
  on_events: [no-capacity]
  duration: 1d

Previously, submitted jobs were processed in a FIFO manner, with older jobs handled first. Now, jobs are first sorted by descending priority. Note that if a high-priority run cannot be scheduled, it does not block lower-priority runs from being scheduled (i.e., best-effort FIFO).

Note

It can also be useful to combine priority with retry to ensure tasks remain queued in case of capacity limits.

The priority field is updatable, so it can be modified for already submitted runs and will take effect.

CLI

dstack project command

The new dstack project command replaces the existing dstack config command.

1. dstack project (same as dstack project list)

$ dstack project

 PROJECT         URL                    USER            DEFAULT
 peterschmidt85  https://sky.dstack.ai  peterschmidt85
 main            http://127.0.0.1:3000  admin              ✓

2. dstack project set-default

$ dstack project set-default peterschmidt85
OK

3. dstack project add (similar to old dstack config, but --project is changed to --name)

$ dstack project add --name peterschmidt85 --url https://sky.dstack.ai --token 76d8dd51-0470-74a7-24ed9ec18-fb7d341
OK

dstack ps -n/--last

The dstack ps command now supports a new -n/--last parameter to show last N runs:

✗ dstack ps -n 3

Azure

Fsv2 series

The Azure backend now supports compute-optimized Fsv2 series:

✗ dstack apply -b azure
