Thanks for the reply. It is not necessary for me to use MPI_SUM. I think the
better choice is MPIU_REPLACE. Doesn’t MPIU_REPLACE work for any mpi_datatype?
Yes.

IIRC, MPI_CHAR is for ASCII text data. Also, remember that in C the signedness

I'm not sure MPI_Reduce() is supposed to / should ha
It is probably not written down anywhere (where would we write it?) nor does
./configure check it but the consensus is that PETSc now requires MPI 2.0 or
later. So developers should feel free to use any MPI 2.0 feature without
guards and if you stumble across older code that still has guard

You could just do
E.getBV().setType(SLEPc.BV.Type.VECS)
before E.setFromOptions()

Hello, everybody,
I use Splec4py to solve the lowest eigenvalues and corresponding
eigenvectors of systems up to 20 Mio x 20 Mio. My problem so far was that
the base was too big. On advice here in the forum I always added -bv_type
vecs -bv_type mat to the command line, what solved my problems. I do
Hello,
thanks to all, I used the wrong RHS and Jacobian function in my
conversion. I modified the code and I got the right solution. I'm
attaching the final code conversion. Someone could be interested in a
Python version of ex13 of the TS component tutorial.
