Hi I have been having (patch 9). I was not having these problems with PETSc v2.3.0.
I am using Spooles downloaded from the PETSc ftp site and built into PETSC_DIR/externalpackages. When solving a partcular problem I am getting the error: MatFactorNumeric_MPIAIJSpooles line 199 src/mat/impls/aij/mpi/spooles/mpispooles.c MatLUFactorNumeric line 2200 src/mat/interface/matix.c KSPSetUp line 183 src/ksp/ksp/interface/itfunc.c KSPSolve line 305 src/ksp/ksp/interface/itfunc.c The problem also occurs in serial. I am using Hypre v1.10.0b downloaded from the LLNL site and built separatly to PETSc. When I have been using Pilut and Parasails as either global problem preconditioners of as sub preconditioners for ASM or BJACOBI, I have been getting errors indicating that there could be a memory access out of range. I suspect that there may be a memory overwrite or mismatch occuring somewhere. Note that BOOMERAMG and EUCLID seem to work OK. Again these problems were not apparent when I was using PETSc v2.3.0. Have there been any significant changes in the PETSc source that handles Spooles and Hypre between versions 2.3.0 and 2.3.1 that could be causing these problems? I don't really want to go back to using PETSc v2.3.0 if I can help it. I don't know if it makes any difference, but I am using the Fortran interface to PETSc. Hope you can help. Regards Stephen R.
