Thanks a lot, Satish. It is much clear now. But for the choice of the two, the program dmidecode does not show this information. Do you know any way to get it?
why do you expect dmidecode to show that?
You'll have to look for the CPU/chipset hardware documentation - and look at the details - and sometimes they mention these details..

Thanks, Satish. Yes, I need to check it. Just now I re-configured PETSC with the option --with-device=ch3:nemsis. The results are almost the same as --with-device=ch3:sock. As can be seen in the attachment. I hope the matrix partitioning - reordering algorithm would have some positive effects.
