DeviceInformation Struct Reference

#include <gromacs/hardware/device_information.h>

Description

Platform-dependent device information.

The device information is queried and set at detection and contains both information about the device/hardware returned by the runtime as well as additional data like support status.

Member Data Documentation

std::array<int, 10> DeviceInformation::supportedSubGroupSizesData

Warp/sub-group sizes supported by the device.

DeviceInformation must be serializable in CUDA, so we cannot use std::vector here. Arbitrarily limiting to 10. FixedCapacityVector uses pointers internally, so no good either.
