I have no idea. That is a good question for the PasTix list.
Thanks,

Hi Junchao/Barry,
It doesn't really matter what the h5 file contains, so I'm attaching a lightly
edited script of
JD sets STPRECOND at EPSSetUp(), if it was not set before. So I guess you need
to add -st_type precond on the command line, so that it is set at
EPSSetFromOptions().

How about I want to determine the ST type on runtime?
mpirun -n 1 ./ex3 -eps_type jd -st_ksp_type gmres -st_pc_type none
-eps_view -eps_target 0 -eps_monitor -st_ksp_monitor
ST is indeed STPrecond, but the passed preconditioning matrix is still
ignored.
EPS Object: 1 MPI processes
type:
Currently, the function that passes the preconditioner matrix is specific of
STPRECOND, so you have to add
ierr = STSetType(st,STPRECOND);CHKERRQ(ierr);
before
ierr = STPrecondSetMatForPC(st,B);CHKERRQ(ierr);
otherwise this latter call is ignored.
We may be changing a little bit the way in
Hello,
After carefully looking at the example in the tutorial suggested in
section 3.4.5 of the manual, I managed to determine that the problem was
caused by me calling EPSSetFromOptions(eps) after
EPSKrylovSchurSetPartitions(eps,size) and not before. It now works fine.
Sorry!
Best regards,
