It may be difficult to narrow down the problem without knowing what commands you're running inside the salloc session. For example, if it's a pure OpenMP program, it can't use more than one node.

Dear All,

May I have your suggestion in my issue facing,

While the job is launched using “salloc -N4--mem 4000 -p active”  I find the job is running in the one compute node and the other 3 machines are free, I don`t find the job is distributed evenly, May I have your suggestion,

I do squeue /scontrol to find the job distribution and it displays the 4 machines but when I check on the respective machines I don`t find the job running only one machine takes the whole node,

Is there any issue in my conf file or what needs to be done, May I have your suggestion pls.

 

FYI, salloc -N4 --mem 4000 -p active

 While using TOP,

I find only Debussy is used heavily, I don`t find my job is evenly distributed, May I have your guidance pls.

 

 

 

 

 

 

Regards,

KumaranS
