We are pleased to announce the availability of Slurm version 17.11.0-0rc1 (release candidate 1). Production release of version 17.11 is expected in November. Interested parties are invited to test this pre-release.
Slurm can be downloaded from https://www.schedmd.com/downloads.php Major changes in version 17.11 include the following: -- Support for federated clusters to manage a single work-flow across a set of clusters. -- Support for heterogeneous job allocations (various processor types, memory sizes, etc. by job component). Support for heterogeneous job steps within a single MPI_COMM_WORLD is not yet supported for most configurations. -- X11 support is not fully integrated with the main Slurm code. Remove any X11 plugin configured in your plugstack.conf file to avoid errors being logged about conflicting options. -- Added new advanced reservation flag of "flex", which permits jobs requesting the reservation to begin prior to the reservation's start time and use resources inside or outside of the reservation. A typical use case is to prevent jobs not explicitly requesting the reservation from using those reserved resources rather than forcing jobs requesting the reservation to use those resources in the time frame reserved. -- The sprio command has been modified to report a job's priority information for every partition the job has been submitted to. -- Group ID lookup performed at job submit time to avoid lookup on all compute nodes. Enable with PrologFlags=SendGIDs configuration parameter. -- Add the configure option --with-shared-libslurm which will link to libslurm.so instead of libslurm.o thus reducing the footprint of all the binaries. -- In switch plugin, added plugin_id symbol to plugins and wrapped switch_jobinfo_t with dynamic_plugin_data_t in interface calls in order to pass switch information between clusters with different switch types. -- Changed default ProctrackType to cgroup. -- Changed default sched_min_interval from 0 to 2 microseconds. -- CRAY: --enable-native-cray is no longer an option and is on by default. If you want to run with ALPS please configure with --disable-native-cray. -- Added new 'scontrol write batch_script <jobid>' command to fetch a job's batch script. Removed the ability to see the script as part of the 'scontrol -dd show job' command. -- Add new "billing" TRES which allows jobs to be limited based on the job's billable TRES calculated by the job's partition's TRESBillingWeights. -- Regular user use of "scontrol top" command is now disabled. Use the configuration parameter "SchedulerParameters=enable_user_top" to enable that functionality. The configuration parameter "SchedulerParameters=disable_user_top" will be silently ignored. -- Change default to let pending jobs run outside of reservation after reservation is gone to put jobs in held state. Added NO_HOLD_JOBS_AFTER_END reservation flag to use old default. See the NEWS file for more details about changes.
