I guess you are using OpenMPI? If yes, than you can safely ignore this warning. The OpenMPI launcher modifies the SLURM environment in unexpected ways which leads to that warning. > > 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 > > > Is this a problem? The program seems to run ok (I'm currently > debugging a different deadlock issue, which is not related I guess). We were having troubles when running with multiple localities up until recently. If you update to today's top of master, at least the problems coming from HPX directly should go away. > > > Thanks! > > Tim _______________________________________________ hpx-users mailing list [email protected] https://mail.cct.lsu.edu/mailman/listinfo/hpx-users
