Function Documentation

int vecmem::hip::details::get_device ( )

Helper function for determining the "currently active device".

Note that calling the function on a machine with no HIP device does not result in an error, the function just returns 0 in that case.

std::string vecmem::hip::details::get_device_name ( int device )

Get a "fully qualified" name for a given HIP device.

This function provides a uniform way for printing the names of the devices that various VecMem objects would be interacting with.

Parameters

device The device ID that the HIP runtime assigned
