Re: MUMPS solve error at DirectSolve.f90: seg fault (OpenMPI)
Update: MUMPS still breaks my Elmer build for this test case when I compile it with Metis 5.1.0. It's bugging out during a cptr = imalloc in ometis.c which invokes a whole slew of mallocs until it finally gets in to the OpenMPI malloc and barfs. I'm posting this to the metis forum to see what they s...

Re: Elmer 8.1 using MUMPS 5.0.1 direct solve: SIGSEGV (11)
Hello, An update. I initially suspected this to be an issue with OpenMPI given the backtrace. However, this is most definitely a ParMETIS issue (from within MUMPS). This is what I did: I recompiled everything from source using OpenMPI 1.10.1 (including LAPACK, OpenBLAS, SCALAPACK, ParMETIS, HYPRE, M...

Re: Parallel
Could you print out what elmer spits out when you invoke it? Paste in the entire output.

MUMPS solve error at DirectSolve.f90: seg fault (OpenMPI)
Hello, I've got this posted in the Bugs forum but thought it might get more traction here. I've installed Elmer 8.1 on CentOS 6.7 with a self-compiled MUMPS 5.0.1 library, using OpenMPI. The suite passes all but 3 tests, including the two mumps tests I can find (mgdyn_harmonic and mgdyn_harmonic_los...

Re: Elmer 8.1 using MUMPS 5.0.1 direct solve: SIGSEGV (11)
Hello, An update. Compiling under normal conditions and running with gdb I get the following stacktrace which seems to point to an error in DirectSolve.F90. Here is the relevant snippet, the entire stacktrace is below. Still wondering if this is something to do with versions, but it seems like a leg...

Elmer 8.1 using MUMPS 5.0.1 direct solve: SIGSEGV (11)
Hello, I've compiled Elmer using a self-compiled MUMPS on CentOS 6.7, both using mpicc and libs from openmpi 1.6.5. (I compiled MUMPS using -fPIC to produce shared libraries, and it passes all the tests it comes with-- so I don't think that's the problem). I plan on submitting a tutorial on how I bu...
