Re: Are My node's working?

Hi,
Please check the homepage, in the documentation section. There is a link to a forum post that explains how to tune the HPL benchmark to get high values. The 4 after -np is the number is the number of MPI ranks to use. Please type "man orterun" to get more information on that.

HPL on PelicanHPC is included mainly as an example of making something run in parallel on the cluster, I personally don't ever  try to tune it to get high numbers, because my attention is elsewhere. I believe that the speed of the network is a limiting factor for most Beowulf style clusters that are what Pelican is usually used to make. Even so, you should be able to get much better numbers with 10 machines, if you are interested in doing so.

Cheers, M.
