Reply To: Multi-GPU usage issue


Hello Adrian,

I retracted back to the original code for the number of cuboids, however, the number of cuboids is set to one after running the code.

const int noOfCuboids = 2*singleton::mpi().getSize();
#else // ifdef PARALLEL_MODE_MPI
const int noOfCuboids = 1;
#endif // ifdef PARALLEL_MODE_MPI

Also, the command #SBATCH –tasks-per-node=8 was added to the SLURM script. It didn’t make any difference.

I observe that the issue stems from the mpi process. There is something not syncing between the mpi process or ranks with the Slurm script. I would appreciate your feedback.

Thank you.

Yours sincerely,

Abhijeet C.
