Parallel modStd().

Parallel modStd().

How many nodes are best for modStd() in parallel? I need to know this so that I ask for the optimal number of nodes, so that I calculate fast, and do not waste limited computer time.

Thank you very much.

Best regards.

Currently, modStd uses only CPUs on the same computer.
By default: all it can find (check which system("cpu");).
This number can be changed with the command line option
--cpus=#CPUs maximal number of CPUs to use.
How many are best depends on your problem,
the algorithm and implementation have no limitation here
(beside system limits: the number of processes, number of open file descriptors ,
available memory, etc.)
