Re: [slurm-users] Wrong hwloc detected?

Looking at the code it's not actually checking the hwloc version, it's finding an error condition and suggesting that may be the cause, but it sounds like it's not for you. src/plugins/task/cgroup/task_cgroup_cpuset.c : /* should never happen in normal scenario */ if ((sock_loop > npdist) && !hwloc_success) { /* hwloc_get_obj_below_by_type() fails if no CPU set * configured, see hwloc documentation for details */ error("hwloc_get_obj_below_by_type() failing, " "task/affinity plugin may be required to address bug " "fixed in HWLOC version 1.11.5"); return XCGROUP_ERROR; } [...] If you've got support from SchedMD open a bug with them, but if not and you're using the Debian packages I'd suggest opening a bug with Debian about it.

Is there a way to estimate the > completion date / time of current running jobs?! We just set up a reservation at a point at a time which is further in the future than our maximum run-time. There is then no need to drain anything. Short running jobs can still run right up to the reservation.

The pestat script from https://github.com/OleHolmNielsen/Slurm_tools/blob/master/pestat also print job ending times on nodes: $ pestat -E | sort -k 11 You can make all sorts of node selections with the other pestat options. /Ole
