v0.12.0-rc1

HyperQueue 0.12.0-rc1

New features

Automatic allocation

• #457 You can now specify the idle timeout
  for workers started by the automatic allocator using the --idle-timeout flag of the hq alloc add command.

Resiliency

• #449 Tasks that were present during multiple
  crashes of the workers will be canceled.

CLI

• #463 You can now wait until N workers
  are connected to the clusters with hq worker wait N.

Python API

• Resource requests improvements in Python API.

Changes

CLI

• #477 Requested resources are now shown while
  submitting an array and while viewing information about task TASK_ID of specified
  job JOB_ID using hq task info JOB_ID TASK_ID

• #444 The hq task list command will now
  hide some details by default, to conserve space in terminal output. To show all details, use the
  -v flag to enable verbose output.

• #455 Improve the quality of error messages
  produced when parsing various CLI parameters, like resources.

Automatic allocation

• #448 The automatic allocator will now start
  workers in multi-node Slurm allocations using srun --overlap. This should avoid taking up Slurm
  task resources by the started workers (if possible). If you run into any issues with using srun
  inside HyperQueue tasks, please let us know.

Jobs

• #483 There is no longer a length limit
  for job names.

Fixes

Job submission

• #450 Attempts to resubmit a job with zero
  tasks will now result in an explicit error, rather than a crash of the client.
