Hi Jose,
With pull request #719 we have finished a set of fixes to VECCUDA stuff. With these changes it is now possible to run many tests in SLEPc's testsuite on GPU (AIJCUSPARSE+VECCUDA). These tests will be included in the nightly tests from now on.
great!
However, PETSc nightly tests related to VECCUDA are not being run. The reason is that arch-cuda-double.py and arch-cuda-double.py have --with-cusp=1 and this option disables VECCUDA code. CUSP tests are separate from VECCUDA tests.
As you may remember, I want to get rid of VECCUSP (and if possible also MATAIJCUSP), because the functionality is now provided natively through the CUDA SDK (VECCUDA, MATAIJCUSPARSE). Only the preconditioners from CUSP, most notably PCSACUSP, will stay. This way we can then easily switch over all the tests to VECCUDA.
Another thing is that not all VECCUDA tests pass, because of a pending issue related to MatMultTranspose_MPIAIJCUSPARSE. This was reported last year: https://bitbucket.org/petsc/petsc/pull-requests/490/gpu-regression-tests
Alright, thanks for the reminder. Let me get this fixed. :-) Best regards, Karli
