[petsc-users] PLAPACK question/issues

[Hamid M.]

Hello

As was suggested on this list, I configured petsc with --download-plapack:

./config/configure.py PETSC_ARCH=intel_R_mpich2 --download-plapack
--with-debugging=0
--with-blas-lapack-dir=/opt/intel/mkl/10.1.1.019/lib/em64t/
--with-mpi-dir=/opt/mpich2/mpich2-1.1-intel-11.1
--with-gnu-compilers=0

Trying to run the PLAPACK tests on our cluster fails.
I am in contact with Robert van de Geijn (the author) of PLAPCK and he
thinks these issues are related to compiling the code on a 64bit
machine.

So I was wondering if anyone in PETSc community is using PLAPCK in
their projects and if they've encounter such problems.

For example, after configuring and building PETSc I ran the test in
'externalpackages/PLAPACKR32-hg/EXAMPLES/LU'
and got this:

Fatal error in MPI_Scatterv: Other MPI error, error stack:

scnts=0x10f02c0, displs=0x10a8fc0, MPI_DOUBLE_COMPLEX, rbuf=0x1526770,
