typedef enum {
  PETSC_DEVICE_HOST,
  PETSC_DEVICE_CUDA,
  PETSC_DEVICE_HIP,
  PETSC_DEVICE_SYCL,
  PETSC_DEVICE_MAX
} PetscDeviceType;

Values#

PETSC_DEVICE_HOST - Host, no accelerator backend found
PETSC_DEVICE_CUDA - CUDA enabled GPU
PETSC_DEVICE_HIP - ROCM/HIP enabled GPU
PETSC_DEVICE_SYCL - SYCL enabled device
PETSC_DEVICE_MAX - Always 1 greater than the largest valid PetscDeviceType, invalid type, do not use
