I have tried with slepc-master and it works:
$ mpiexec -n 2 ./ex1 -eps_ciss_partitions 2
matrix size 774

(-73.9569,-42.2401)

(-57.9883,0.298729)
(-57.8323,1.06041)
(-56.5317,1.10758)
(-56.0234,45.2405)

Hong,
do you have in mind a reason why the newer version should work or is it a
general recommendation?
Which stable version would you recommend to upgrade to?
Thank you,
Michael.

Hello Jose,
I have done the test case to reproduce my error.
1. You will need to download a file "matrix.bin" from the following link
https://www.dropbox.com/s/6y7ro99ou4qr8uy/matrix.bin?dl=0
2. Here is the C++ code I use

Michael,
In my previous email I should have checked it better. The CISS solver works
indeed with dense matrices:
$ mpiexec -n 2 ./ex2 -n 30 -eps_type ciss -terse -rg_type ellipse
-rg_ellipse_center 1.175 -rg_ellipse_radius 0.075 -eps_ciss_partitions 2
-mat_type dense
2-D Laplacian Eigenprobl
Michael,
We have support of MatCreateRedundantMatrix for dense matrices. For
example, petsc/src/mat/examples/tests/ex9.c:
mpiexec -n 4 ./ex9 -mat_type dense -view_mat -nsubcomms 2

Dear Petsc developers,
I found that MatCreateRedundantMatrix does not support dense matrices.
This causes the following problem: I cannot use CISS eigensolver from
SLEPC with dense matrices with parallelization over quadrature points.
Is it possible for you to add this support?
Thank you,
Mic
