Sam,
The MPI_Comm_create_keyval() error was fixed in maint/master. From the
error message, it seems you need to configure --with-log=1
Otherwise, please send your full error stack trace and configure.log.
Thanks.

Mark,
Thanks for letting us know. We have added it to the PETSc package list.
Should any issues come up we'll be glad to help support it.

Please send the code. This should work fine.

Rakesh,
Can you find the condition number of your matrix A?

Hi all,
I'm using PETSc for matrix calculations as part of a model order reduction
code. An algorithm I'm using requires that I compute the explicit inverse
of a matrix, as it needs to be used in matrix-matrix products.
The matrix is small (I'll show a 5x5 example), and I first find the LU
factor
Hi Junchao,
I now encountered the same error with parallel. I am wondering if there
is a need for parallel fix as well.

You might have forgotten to call PetscInitial

Late followup, but people may want to know that a PETSc/OpenFOAM
interface is included in the pending OpenFOAM-v2006 release as a git
submodule:
https://develop.openfoam.com/modules/external-solver
