Dear all, I just wanted to add what we found in case that it can help to solve this problem:
* Examples ex2.c, ex11.c and ex32.c under src/ksp/ksp/tutorials all of them seg-fault with "-mat_type mpiaijcusparse" or "-vec_type mpicuda" with CUDA 9.2 and 10.2. Examples ex2.c and ex32.c work fine if PETSc scalar type is set to real instead of complex. PETSc has been compiled with gcc-6.4.0 * Here: https://dynamite.readthedocs.io/en/latest/tips.html#gpu-support it is mentioned that there is some problem for CUDA versions 8 and above. * It seems that the same problem was mentioned in this thread: https://lists.mcs.anl.gov/mailman/htdig/petsc-users/2019-February/037748.html Please, let me know if you need any extra information. Thank you very much for your help. Best regards, Jorge
