Questions on potential test scenarios

[ansiblejunky]

We are using this tool to perform performance tests on GPU clusters. We had a few questions:

• Do you provide an option to simply perform a ping test (no package sending) between the same points? This would be a helpful test that is much quicker than running the performance package tests.
• Do you provide an option to run bi-directional package sending? We noticed the time to complete all combinations of all NICs and each direction can be exhaustive. How might we confidently test bi-directionally?
• Can you help explain with examples on testing CPU and GPU during these benchmarks? thank you
• Do you provide parameters that set thresholds on the performance tests so that an error can be raised when those thresholds are not met? This would help so we don't have to manually parse all of the output data.
