Execution of serial code on 1 physical core of Gold 6128 and E-2176G processors on the devcloud

Hello,
I need to get the execution time of a serial code on 1 physical core of the gold 6128 and E-2176G processors. How do I request for 1 physical core with the qsub command. I have tried using (Gold 6128) :

qsub -I -l ncpus=1,

qsub -I -l procs=1,

but I still obtain same timings as when I request using: qsub -I -l nodes=1:ppn=2

 

Thank you.

Kind regards

Oluwatosin.

Hi,


Could you please try the below qsub command to request for 1 physical core :

qsub -l nodes=1:ppn=1

which gives us an allocation of 1 core on one node.


Let us know the updates.


Thanks and Regards,

Raeesa

Hello, 

 

I get this: 

ERROR in qsub arguments:

Compute nodes in this cabinet are configured with 2 slots per node,
but you included the argument "-l nodes=1:ppn=1", which results in 1 slot per node.
With this argument, your application will not have full control over its node(s).
Please run with "-l nodes=1:ppn=2" instead.

Hi,


Sorry for the delayed response. We were checking from our end regarding requesting a single physical core and tried different methods from our end but unfortunately requesting 1 physical core is not possible. Lets us know if you have any further queries. Can we discontinue monitoring this thread ?
