General usage information

Gloo is a collective communications library that 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 one can use IP or InifiniBand.

The following environmental variables have been defined:

• \$GLOO_ROOT has been set to the root of the gloo installation
• \$GLOO_LIBDIR points to the directory containing the libraries
• \$GLOO_INCDIR points to the directory containing the header files

You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):

• -I\$GLOO_INCDIR

and the following flags to your link command (e.g. LDFLAGS in your Makefile):

• -L\$GLOO_LIBDIR -Wl,-rpath,\$GLOO_LIBDIR
