[hpx-users] SLURM: requesting a different number of localities than have been assigned

[Tim Biedert]

Hi,






In the program however HPX correctly reports two localities.

The warning is similar for other node counts (e.g. 4/3 or 16/15).


My submit file basically looks like this:

#!/bin/bash

#SBATCH -t 20
#SBATCH -N 2
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=16
#SBATCH --mem=62G

mpirun ./myapp --hpx:threads 16





Thanks!

Tim

when running my application on our (new) SLURM cluster, I receive the following warning (if using more than one node): hpx::init: command line warning: --hpx:localities used when running with SLURM, requesting a different number of localities (2) than have been assigned by SLURM (1), the application might not run properly. Is this a problem? The program seems to run ok (I'm currently debugging a different deadlock issue, which is not related I guess).
