[petsc-users] MUMPS solver crash with petsc-3.2

[Gong Ding]

I can only analysis the core file at present.
It reported 
Program terminated with signal 11, Segmentation fault.
#0  0x000000010217319c in dmumps_462 ()
Run program with -info, the output is
Entering DMUMPS driver with JOB, N, NZ =   1          49            217
 DMUMPS 4.10.0
L U Solver for unsymmetric matrices
Type of parallelism: Working host
 ****** ANALYSIS STEP ********
 Resetting candidate strategy to 0 because NSLAVES=1
 ... Structural symmetry (in percent)=  100
 Density: NBdense, Average, Median   =    0    3    3
 ... No column permutation
 Ordering based on AMF
Program terminated with signal SIGSEGV, Segmentation fault.
The example in src/ksp/ksp/examples/tests/ex3 run ok -- it solves a small linear problem.
Also, if I reduce the matrix size to ~20x20, no crash happen.
I'll try to provide more information.

Bad news.
MUMPS still crash on AIX/PPC.
I tried petsc-3.1, 3.2 and dev. All of them crash with ERROR: 0031-250  task 0: Segmentation fault.
I guess the interface of petsc-mumps has some problem, i.e. alignment.
Please get a stack trace with the debugger.
   Matt  Yes, petsc-dev works. Please merge the update to petsc-3.2.
Parmetis 4.0 was released after PETSc 3.2 so it will not be updated to work with it. In general, software projects don't update a previous release on a dependent package update. Please use petsc-dev or wait until PETSc 3.3.
