[mcstas-users] Using Monitor_nD + Multicore

[farhi]

Hi Mark,

the merging of data files after SSH grid is done through the 'mcformat'
tool. This latter works on text files for e.g. histograms. For lists,
you should catenate the event files one after the other if mcformat
fails.

However, I'd be interested to get your log file, and the associated
instrument file if possible.
I tend to prefer MPI on multi-core machine/cluster, than the SSH
mechanism, so it's a long time since I used it, I must admit.

Cheers, Emmanuel.
