Good morning, I'm running an NPB test, bt.C that is OpenMP and built using NV HPC SDK (version 25.1). I run it on a compute node by ssh-ing to the node. It runs in about 19.6 seconds.
Then I run the code using a simple job: Command to submit job: sbatch --nodes=1 run-npb-omp The script run-npb-omp is the following: #!/bin/bash cd /home/.../NPB3.4-OMP/bin ./bt.C.x When I use Slurm, the job takes 482 seconds. Nothing really appears in the logs. It doesn't do any IO. No data is copied anywhere. I'm king of at a loss to figure out why. Any suggestions of where to look? Thanks! Jeff
