We are pleased to announce the availability of Slurm release candidate
version 20.11.0rc1.
Slurm 20.11 includes a number of new features including:
- Overhaul of the job step management and launch code, alongside
improved GPU task placement support.
- A new "Interactive Step" mode of operation for salloc.
- A new "scrontab" command that can be used to submit and manage
periodically repeating jobs.
- IPv6 support.
- Changes to the reservation logic, with new options allowing users to
delete reservations, allowing admins to skip the next occurance of a
repeated reservation, and allowing for a job to be submitted and
eligible to run within multiple reservations.
- Dynamic Future Nodes - automatically associate a dynamically
provisioned (or "cloud") node against a NodeName definition with
matching hardware.
- An experimental new RPC queuing mode for slurmctld to reduce thread
contention on heavily loaded clusters.
Please see the RELEASE_NOTES distributed alongside the source for
further details.
This is the first release candidate version of the upcoming 20.11
release series, and represents the end of development for the release
cycle, and a finalization of the RPC and state file formats.
If any issues are identified with this new release candidate, please
report them through https://bugs.schedmd.com against the 20.11.x version
and we will address them before the first production 20.11.0 release is
made.
Please note that the release candidates are not intended for production
use. Barring any late-discovered issues, the state file formats should
not change between now and 20.11.0 and are considered frozen at this
time for the 20.11 release.
