MatMatMult_MPIDense_MPIDense() works currently?

Fri Sep 18 15:37:57 CDT 2009

You may test your plapack installation using
/src/mat/examples/tests/ex103.c or ex107.c

See runex103 ore runex107
in /src/mat/examples/tests/makefile.

Hmm, ex123.c is a test for MatMatMult() using plapack.
runnning it, I get
[1]PETSC ERROR: Error in external library!
[1]PETSC ERROR: Due to aparent bugs in PLAPACK,this is not currently 
supported!

Thus, as it says, MatMatMult() for mpidense matrix is not
supported.
