Commit bb203b711405faa7273ad38dd7eaa078903db820 by brice.goglin
distances: add MERGE_SWITCH_PORTS and TRANSITIVE_CLOSURE transformations

Those are currently specific to NVIDIA GPUs connected through a NVSwitch.
The NVLinkBandwidth exposes bandwidth from GPUs to 6 individual NVSwitch ports.

MERGE_SWITCH_PORTS will combine all switch ports into a single object.
We loose the PCI locality (one half of the switch is on each socket)
but it doesn't matetr much.

TRANSITIVE_CLOSURE gives inter-GPU bandwidth across the NVSwitch.

The XGMIBandwidth is not affected for now because XGMI traffic cannot
be routed through GPUs or switches yet.

hwloc-annotate should be used for more features.

tests/xml: add power8 distances between NVIDIA GPUs and Packages

Restricted horizontally (only 2 PU per core, and 4 cores par packages)
Restricted vertically (removed caches).
Removed all I/Os except GPUs.
