Reply To: Problem with multi GPU

[thanhphatvt]

Dear Adrian,
When I use the mpi with 2 GPUs for running the simulation and I got the problem with the results. I can not open the result with Paraview. Here is the errors in Paraview

What should I do in this situation? Or Did I make something wrong in the simulation?
Thank you Adrian!
