[petsc-users] Errors about PETSc MPI+GPU

[Xinzhe Wu]

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!
