high-core-count cpu

[edhan]

Hi,

I run a HPC application which needs a high-core-count cpu to check the OpenMP performance. Currently qsub allocates a computer node with only two 6-core CPUs. Is there a computer node with higher core count? Thanks.

Hi,

Thank you for reaching out. According to your query, you require more than 6 cores per socket. Here are the nodes which fit this requirement:

1. In devcloud, nodes with cpu: i9-10920x have these features

     >    ncpus: 24

           Thread(s) per core: 2

           Core(s) per socket: 12

           Socket(s):          1

To use those nodes, execute the below command which will provide the user with available node having these properties

qsub -I -l nodes=1: i9-10920x:ppn=2

2. The nodes with properties: renderkit

     >    ncpus: 64

           Thread(s) per core: 2

           Core(s) per socket: 16

           Socket(s):          2

     To use those nodes, execute the below command which will provide the user with available node having these properties

qsub -I -l nodes=1:renderkit:ppn=2

The nodes are subjected to availability. To know about the nodes, their properties, availability and for ncpus information, please execute the command :

pbsnodes
