[Gate-users] Fwd: Problems with concurrent simulations

[Clemens S.]

Dear fellow Gate-users,

I'm contacting you again because of persisting multiprocess issues on
Ubuntu 16.04 and Gate 7.2, using Fixed Forced Detection. I'm attaching the
email I sent two weeks ago, to which sadly nobody answered. (there should
be a .zip of my simulation folder attached; please tell me if this got lost
by the mailing list.)

This may be a fringe use case and not easy for somebody to understand my
macro and help me, but I really am out of luck on this issue. I would be
immensely grateful if somebody could help me or give me any ideas. Maybe
somebody has experience with concurrent Fixed Forced Detection-MC ?

I am looking forward to your ideas.

Kind regards
Clemens Schmid

Dear fellow Gate-Users,

I've already posted on the mailing list a month ago because of problems
with performing multiple concurrent Gate simulations.
A few people gave me suggestions for which I am very thankful, despite not
getting back to you.

Nevertheless, I still have the same problems.

I attached a zip of the simulation folder. The run.sh script can be used to
start the simulations, although I myself start them from Python with the
subprocess module (because I use a Python framework to construct the
simulations). The problem is the same for both situations, though:
When I start the simulations, they stay a very long time at "[Core-0]
Initialization of geometry" (see log file in logs/ folder). I played around
with the verbosity settings, but I could not find any hints to the reason
for this. When I run a single simulation, it doesn't hang at all.

I also tried to launch concurrent simulations from seperate folders, one
for each simulation -- so that they don't read from the same files. That
didn't make a difference.
I should also note that all this happened on local storage.

I want to apologize for my lack of communication after last month's
question. Other issues got in my way and I now again have time to work on
the multiprocess issues.
I'm looking forward to your suggestions! Thank you very much for your help.

Best regards
Clemens Schmid
