[petsc-users] SuperLU MPI-problem

Run the program under valgrind http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind . When I use the option -mat_superlu_dist_parsymbfact I get many scary memory problems some involving for example ddist_psymbtonum (pdsymbfact_distdata.c:1332)
Note that I consider it unacceptable for running programs to EVER use uninitialized values; until these are all cleaned up I won't trust any runs like this.
