Hi Nek's

I'm going to run Nek5000 on a Bull cluster.  In order to submit the
process, i have to set the number of nodes, of tasks per node and of
threads per core. Setting the threads per core equals to one, how can I
adjust the number of nodes and the number of cores per node keeping Nek5000
in an optimal arrangement?

In my case, I have 33000 elements with a spectral order equal to 8.
