std::vector< int >	gmx::parseUserGpuIdString (const std::string &gpuIdString)
	Parse a GPU ID specifier string into a container describing device IDs exposed to the run. More...
std::vector< int >	gmx::makeListOfAvailableDevices (gmx::ArrayRef< const std::unique_ptr< DeviceInformation >> deviceInfoList, const std::string &devicesSelectedByUserString)
