How To: how-can-i-utilise-maximum-number-of-nodes-for-parallel-computing-of-jobs-in-intel-devcloud

QUESTION: 

 

 

How can I utilize maximum number of nodes for parallel computing of jobs in Intel DevCloud?

for i in range(1,101,1):

  !qsub myjob -F "0" -o ./my_log_output.txt -e ./my_log_errors.txt

_____

After initializing 100 jobs with the above code I checked the status of queue using "qstat". The result shows that only 20 are running at any given instant and the remaining are in queue, whereas the "pbsnodes" command is outputting 136 nodes.

How can I utilise all these 136 nodes in parallel?

_____

 

!qstat -a

ANSWER:

In order to maintain a fair utilization for all those who works in Devcloud , there is a restriction in the max number nodes that can be availed by a single user.
