#include "petscsys.h" PetscErrorCode PetscCUDAInitialize(MPI_Comm comm)Logically collective
-cuda_initialize <default yes,no> | - do the initialization in PetscInitialize(). If -cuda_initialize no is used then the default initialization is done automatically when the first CUDA call is made unless you call PetscCUDAInitialize() before any CUDA operations are performed | |
-cuda_view | - view information about the CUDA devices | |
-cuda_synchronize | - wait at the end of asynchronize CUDA calls so that their time gets credited to the current event; default with -log_view | |
-cuda_set_device <gpu> | - integer number of the device | |
-use_gpu_aware_mpi | - Assume the MPI is GPU-aware when communicating data on GPU |
