Slurm threads per core
Webb12 apr. 2024 · I have a workstation with 2x Intel Xeon Gold 6248R, each with 24 cores and threaded---so, 48 total cores, 96 total threads. I have a program parallelized using OpenMPI which I want to have run on all 48 processors, using 1 thread per processor. I am employing Slurm on this workstation to schedule jobs. Webb1 juni 2024 · In Slurm the number of tasks is essentially the number of parallel programs you can start in your allocation. By default, each task can access one CPU (which can be core or thread, depending on config), which can be modified with --cpus-per-task=#.. This in itself does not tell you anything about the number of nodes you will get.

WebbSlurm has options to control how CPUs are allocated. See the man pages or try the following for sbatch. --sockets-per-node=S : Number of sockets in a node to dedicate to a job (minimum) --cores-per-socket=C : Number of cores in a socket to dedicate to a job (minimum) --threads-per-core=T : Number of threads in a core to dedicate to a job … WebbUse the "snodes" command to find the total number of CPU-cores per node for a given cluster.

Webb3 feb. 2024 · Slurm can only allocate cores, not threads. So, with such a configuration: S:C:T 2:26:2 two threads are allocated to jobs for each core being requested. Two hardware threads cannot be allocated to distinct jobs. You can try with--ntasks=1 --cpus-per-task=2 --threads-per-core=2 But, if your computation is CPU-intensive, this can make …
