Re: [sparta-users] Error Opening log.sparta during MPI execution

[Abdourahmane D. <abd...@gm...>]

Hi Steve,

Thank you for taking the time to respond to my question. I have looked at
the permissions, which was not the issue. I also added a line in my script
to cd into my folder. But the problem remains. Interestingly, the problem
disappears when using mpirun rather than jsrun. However, folks at olcf
recommend using jsrun on the Summit.

Yes, I can % touch log.sparta.

I run via a batch script with "cd" to my folder.

#BSUB -W 00:10

#---------------------------------------

cd /ccs/home/abdou/test_spa

jsrun --stdio_mode=prepend -D CUDA_VISIBLE_DEVICES   -E OMP_NUM_THREADS=4
> --nrs 2   --tasks_per_rs 21   --cpu_per_rs 21   --gpu_per_rs 0
> --bind=proportional-packed:1   -d plane:21
> /ccs/home/abdou/sparta/build/src/spa_mpi -in in.free



Hopefully, the olcf folks can help fix this problem as it seems to be
something other than a SPARTA/LAMMPS problem.
