%description
Gloo is a collective communications library. It comes with a number of
collective algorithms useful for machine learning applications. These
include a barrier, broadcast, and allreduce.

Transport of data between participating machines is abstracted so that
IP can be used at all times, or InifiniBand (or RoCE) when available.
In the latter case, if the InfiniBand transport is used, GPUDirect can
be used to accelerate cross machine GPU-to-GPU memory transfers.

Where applicable, algorithms have an implementation that works with
system memory buffers, and one that works with NVIDIA GPU memory buffers.
In the latter case, it is not necessary to copy memory between host and
device; this is taken care of by the algorithm implementations.
