dispy node is not using all cores of CPUs of one node

Hi All,

When I start dispy node with 8 cpu cores, when I submit a job, it's not using all it's cores. I see only one core is being used. Are there any ways to utilize all cores forcefully? When I trigger the top command, I see only one python process.

Thanks.

One dispy job uses one CPU. To use more CPUs, you should submit more jobs. You can submit more jobs than available CPUs, in which case dispy scheduler will run at most as many jobs as available CPUs and submit more jobs as some jobs are finished.
