I try to code a DPC++&MPI Poisson solver and I attach the code and the makefile in the attachment. The code works well and I try to figure out if I am running it by multi-devices. When I perform strong scaling and weak scaling it seems that the code only works on one device or the maximum number of devices but does not work on the number of devices I set up by command. Because When I increase the core number, the performance keeps the same.
I run the code by mpirun -np num ./main
Selected device:NVIDIA A100-SXM4-40GB
The system information is: #101-Ubuntu SMP , Ubuntu 18.04.
