This distribution contains tools that work together with the ibsim tool, available from openfabrics.org. (Or packaged by your linux distribution, i.e. install ibsim-utils package on debian based systems.)

For these tools to work we need the directory where the umad2sim library, libumad2sim.so, is installed, typically /usr/lib/umad2sim.

If you don't have ibsim installed or don't need the tools based on ibsim select cancel.

Please install opensm, and ensure that you can execute the opensm binary system-wide, i.e. the binary can be found in your PATH.
