PetscDeviceType

Kind of accelerator device backend

Synopsis

#include <petscdevicetypes.h> 
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

Note

One can also use the PETSC_DEVICE_DEFAULT() routine to get the current default PetscDeviceType.
