    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

TLTR: do not compare -j8 and -j96, compare -j8 for both systems.
Difference of -j8 and -j96 is another problem not much related to
different hardware.

Long answer:

to answer / give you some hints, we need more information, e.g. the
script you are running.

> I open the yade simulation, show 3D

how it behaves without any GUI?

> The speed ... is slower ... it is very very obviously.

please be more specific what "very obviously" means. 10% slower ? 3x
slower? 1000x slower?

> On the server ... -j96
> On the PC ... -j8

what are the results if you use e.g. -j 4 (or the same -j) for both
systems?

In general, it is not very good idea to compare -j 8 and -j 96, it is
then very different situation, very much depending on the simulation
itself..

cheers
Jan
