Parallel simulation

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Hi Mike,

to run Yade in parallel, do everytihn the same as normally and just use -j option at startup. So to run Yade on 4 cores, use
yade -j 4
or
yade -j 4 script.py

cheers
Jan

Sorry, probably everybody (based on my experience) missed the question

Dear Jan,

Thank you so much for your answer. It's short but very clear answer!

Luckily,  you didn't forget my question :)

Cheers,
Mike

Hi,

Note that whether YADE operations are distributed or not among several cores (leading eventually to a speed-up, or not) also depends on the source code (in addition to providing the -j option). For instance, many engines are now "parallelized", but not all of them.

Hi again,

Following your guidance, I'm ok to run YADE on my computer (with 7 cores) (Open MP). Is that ok for running YADE in server (I mean run YADE in MPI)?

Thank you for your help.

Mike

Hi Mike,
currently YADE does not support MPI (distributed memory) parallelization.
However, you can still use shared memory parallelization even on server
(limited to one computer).
cheers
