Dear all, We have developed the codes with PETSc + SLEPc which works well on CPU version. Now we want to try these codes with GPU + MPI, but get some weird errors shown as below.
I have found someone talked about this problem here http://lists.mcs.anl.gov/pipermail/petsc-dev/2016-March/018836.html , but I can hardly understand it. Can anyone help me with these issues? Thank you in advance!
