by Marshall Garey 08 Apr '25

08 Apr '25

We are pleased to announce the availability of Slurm version 24.11.4. This release fixes a variety of major to minor severity bugs. Some edge cases that caused jobs to pend forever are fixed. Notable stability issues that are fixed include: * slurmctld crashing upon receiving a certain heterogeneous job submission. * slurmd crashing after a communications failure with a slurmstepd. * A variety of race conditions related to receiving and processing connections, including one that resulted in the slurmd ignoring new RPC connections.

Slurm versions 24.11.2 and 24.05.6 are now available
by Marshall Garey 25 Feb '25

25 Feb '25

We are pleased to announce the availability of Slurm versions 24.11.2 and 24.05.6. 24.11.2 fixes a variety of minor to major bugs. Fixed regressions include loading non-default QOS on pending jobs from pre-24.11 state, pending jobs displaying QOS=(null) when not explicitly requesting a QOS, running jobs that requested multiple partitions potentially having an incorrect partition when slurmctld is restarted, and burst_buffer.lua failing if slurm.conf is in a non-standard location. This release also fixes a few crashes in slurmctld: crashing when a job that can preempt requests --test-only, crasing when the scheduler evaluates a job on nodes with suspended jobs, and crashing due to a long-standing bug causing a job record without job_resrcs. 24.05.6 fixes sattach with auth/slurm, a slurmrestd crash when using data_parser/v0.0.40, a slurmctld crash when using job suspension, a performance regression for RPCs with large amounts of data, and some other moderate severity bugs.

23 Jan '25

We are pleased to announce the availability of Slurm version 24.11.1. This fixes a few possible crashes of the slurmctld and slurmrestd; a regression in 24.11 which caused file transfers to a job with sbcast to not join the job container namespace; mpi apps using Intel OPA, PSM2 and OMPI 5.x when ran through srun; and various minor to moderate bugs.

Slurm version 24.11 is now available
by Tim Wickberg 29 Nov '24

29 Nov '24

We are pleased to announce the availability of the Slurm 24.11 release. To highlight some new features in 24.11: - New gpu/nvidia plugin. This does not rely on any NVIDIA libraries, and will build by default on all systems. It supports basic GPU detection and management, but cannot currently identify GPU-to-GPU links, or provide usage data as these are not exposed by the kernel driver. - Add autodetected GPUs to the output from "slurmd -C". - Added new QOS-based reports to "sreport". - Revamped network I/O with the "conmgr" thread-pool model. - Added new "hostlist function" syntax for management commands and configuration files. - switch/hpe_slingshot - Added support for hardware collectives setup through the fabric manager. (Requires SlurmctldParameters=enable_stepmgr) - Added SchedulerParameters=bf_allow_magnetic_slot configuration option to allow backfill planning for magnetic reservations. - Added new "scontrol listjobs" and "liststeps" commands to complement "listpids", and provide --json/--yaml output for all three subcommands. - Allow jobs to be submitted against multiple QOSes. - Added new experimental "oracle" backfill scheduling support, which permits jobs to be delayed if the oracle function determines the reduced fragmentation of the network topology is sufficiently advantageous. - Improved responsiveness of the controller when jobs are requeued by replacing the "db_index" identifier with a slurmctld-generated unique identifier. ("SLUID") - New options to job_container/tmpfs to permit site-specific scripts to modify the namespace before user steps are launched, and to ensure all steps are completely captured within that namespace. The Slurm documentation has also been updated to the 24.11 release. (Older versions can be found in the archive, linked from the main documentation page.) Slurm can be downloaded from https://www.schedmd.com/download-slurm/ . - Tim -- Tim Wickberg Chief Technology Officer, SchedMD LLC Commercial Slurm Development and Support

by Marshall Garey 12 Nov '24

12 Nov '24

We are pleased to announce the availability of Slurm release candidate 24.11.0rc1. To highlight some new features coming in 24.11: - New gpu/nvidia plugin. This does not rely on any NVIDIA libraries, and will build by default on all systems. It supports basic GPU detection and management, but cannot currently identify GPU-to-GPU links, or provide usage data as these are not exposed by the kernel driver. - Add autodetected GPUs to the output from "slurmd -C". - Added new QOS-based reports to "sreport". - Revamped network I/O with the "conmgr" thread-pool model. - Added new "hostlist function" syntax for management commands and configuration files. - switch/hpe_slingshot - Added support for hardware collectives setup through the fabric manager.

This is the first release candidate of the upcoming 24.11 release series, and represents the end of development for this release, and a finalization of the RPC and state file formats. If any issues are identified with this release candidate, please report them through https://bugs.schedmd.com against the 24.11.x version and we will address them before the first production 24.11.0 release is made. Please note that the release candidates are not intended for production use. A preview of the updated documentation can be found at https://slurm.schedmd.com/archive/slurm-master/ .

Slurm version 24.05.4 is now available (CVE-2024-48936)
by Tim Wickberg 23 Oct '24

23 Oct '24

Slurm version 24.05.4 is now available and includes a fix for a recently discovered security issue with the new stepmgr subsystem. SchedMD customers were informed on October 9th and provided a patch on request; this process is documented in our security policy. [1] A mistake in authentication handling in stepmgr could permit an attacker to execute processes under other users' jobs. This is limited to jobs explicitly running with --stepmgr, or on systems that have globally enabled stepmgr through "SlurmctldParameters=enable_stepmgr" in their configuration. CVE-2024-48936.
