Re: [Getfem-users] Getfem in parallel, run error

[Yves Renard]

Dear Guerric,

Can you try again without the automatic refinement option in the file elastostatic.param (REFINE = 0).
I think the computation of a posteriori error criterion is not well parallelized (I planned to work on the stabilization of the parallelization on a near future).

Yves.

Dear Getfem users,

I think I need your help. I have two processor core, I successfully compiled the library in parallel mode (mpich2, mumps 4.10) and when I run the elastostatic file with the command:

mpirun-np 2. / elastostatic. / elastostatic.param

I have the following errors:

I tried several version of metis, but it changes nothing. I saw Daniele Bettella (https://mail.gna.org/public/getfem-users/2008-07/msg00006.html) had had the same problem, but the answer is not in the archives.

Someone already solved this problem? Any ideas?

Thank you in advance,

regards,

Guerric
