HI Markus,
ok I waiting for it!
I have imagined that mpi can benefit of th K40…Seem not true.
A question : with mpi I benefit better way to use my processors.
I have 31cores but this is work better with -np 15(wich give the simulation quicker).
How explain that ?
machine use a XEON E5-2620v4@2.1Ghz with 31 cores
