In my previous email, I tested petsc-dev/src/mat/examples/tests/ex123.c
on MatMatMult_MPIDense_MPIDense() and get error:
Hmm, ex123.c is a test for MatMatMult() using plapack.

Thanks Hong, I tested this examples (ex103.c and ex107.c) and worked fine !
Now I want to multiply two dense matrices using BLAS3 routines. I try to use

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.

Hi everyone, I have the same problem and I don't know how to fix it.
I need to multiply two mpi dense matrices using the BLAS3 routines. I have
tried the MatMatMult_MPIDense_MPIDense() function but the console shows this
message:
[0]PETSC ERROR:

Give us the exact command line you use for ex123 and the error output. Send
to petsc-maint.

I am wondering whether MatMatMult_MPIDense_MPIDense() works currently based
on PLAPACK? Thanks a lot.
