Hi guys, sorry to wake up so late, but, I tried to find info concerning the -j/ --jobs option and could not really sort it all due to my lack of Linux oriented knowledge... As I understand, YADE now run 1 thread (job?) per core. Nonetheless, what would be the command to make it run 1 thread over several/all cores in order to speed up the calculation (if it is the right thing to do for this purpose)?
