for srun jobs, if we try to get UserCPU time by sacct. it always shows 0.
Hi we have a slurm v25.05.2 setup. we found any srun jobs are always shows 0 on UserCPU . for sbatch jobs shoiws normal. is this expected or it is a bug ? Thanks. sacct -j 2948 --format=AveCPU,UserCPU AveCPU UserCPU ---------- ---------- 00:00:00 00:02:00 00:00:00
Hi, We have noticed the same issue: when using JobAcctGatherType=jobacct_gather/linux, the reported CPU usage is 0 for all steps. If the user only use sbatch without using any step (so no srun) then the value is correct. jobacct_gather/cgroup reports correct values for CPU, but wrong values for memory so pick your poison (cf. https://groups.google.com/g/slurm-users/c/tlFA2e74wZc ). If CPU usage is what matters to you, you should probably switch to jobacct_gather/cgroup if you don't use it already.

Hello! We also see this. But in both clusters one is configured with jobacct_gather/linux and the other with jobacct_gather/cgroup. Both cluster are in one setup (slurmdbd) Best! Sven On 2/9/26 10:16, Guillaume COCHARD via slurm-users wrote:

Hello, This is an issue we already reported to the support[1]. For your information, we were using jobacct_gather/cgroup when we encountered this problem. The fix[2] is in the master branches for 25.05 and 25.11 and should be in the next minors (25.11.4 and 25.05.07). Best, Brice [1] https://support.schedmd.com/show_bug.cgi?id=24366#c10 [2] https://github.com/SchedMD/slurm/commit/4890b1a1739bae01ce4adbb552e570723d1e... ________________________________ De : Sven Sternberger via slurm-users <slurm-users@lists.schedmd.com> Envoyé : lundi 16 février 2026 14:46 À : slurm-users@lists.schedmd.com Objet : [slurm-users] Re: for srun jobs, if we try to get UserCPU time by sacct. it always shows 0.
