MaxFlops' performance on multiple GPUs about shoc HOT 2 CLOSED

I think the shocdriver script works differently than you are expecting. The intent is that it reports the best observed MaxFlop value from any device in the system, not the sum of the MaxFlop values across all devices in the system.

That said, I believe the findanymean function in the shocdriver script is incorrectly identifying which number to report. findanymean is only used when reporting the MaxFlops, so it only affects the reporting of that metric's value. We're investigating how to fix this.

Commit cae885b fixed the incorrect shocdriver script results for MaxFlops (and for QTC) running with multiple devices.

A correction to my comment from yesterday - the shocdriver script reports the mean value of the best MaxFlops values for each device in the system. So one can multiply the reported value by the number of devices the driver was run on and obtain the total measured MaxFlops for the devices used.
