Interoperability with Myrinet Express

## Functions
static int | hwloc_mx_board_get_device_cpuset (hwloc_topology_t topology, unsigned id, hwloc_cpuset_t set)
static int | hwloc_mx_endpoint_get_device_cpuset (hwloc_topology_t topology, mx_endpoint_t endpoint, hwloc_cpuset_t set)

## Detailed Description

This interface offers ways to retrieve topology information about Myrinet Express hardware.

## Function Documentation

static int hwloc_mx_board_get_device_cpuset | ( | hwloc_topology_t | topology,
|  | unsigned | id,
|  | hwloc_cpuset_t | set
| ) |  |
| inlinestatic

Get the CPU set of logical processors that are physically close the MX board `id`.

Return the CPU set describing the locality of the Myrinet Express board whose index is `id`.

Topology `topology` and device `id` must match the local machine. I/O devices detection is not needed in the topology.

The function only returns the locality of the device. No additional information about the device is available.

static int hwloc_mx_endpoint_get_device_cpuset | ( | hwloc_topology_t | topology,
|  | mx_endpoint_t | endpoint,
|  | hwloc_cpuset_t | set
| ) |  |
| inlinestatic

Get the CPU set of logical processors that are physically close the MX endpoint `endpoint`.

Return the CPU set describing the locality of the Myrinet Express board that runs the MX endpoint `endpoint`.

Topology `topology` and device `id` must match the local machine. I/O devices detection is not needed in the topology.

The function only returns the locality of the endpoint. No additional information about the endpoint or device is available.
