Reply To: Multi GPUs Calculation

Dear Adrian,

Thank you for reply.

I’m catching on.

You said that “No, you do not need to add or change anything in order to use any kind of parallel processing in OpenLB”. In examples/laminar/cavity3dBenchmark, why is mpi API used such as gpu::cuda::device::synchronize();? Following your useful comments, I think it is not necessary.
I apologize that my comprehension is lacking.
