Performance issue with GPU nodes on cui-gpu-EL7

Could this be why I am experiencing issues on cui-gpu-EL7?
I launched twice the same script on cui-gpu-EL7 over the past 2 days and I experienced a huge slowdown: from 206m to 4534m computation time for a single iteration. (Things seems to be back to normal now though for the new scripts that I launch)

Dear Alexandre,

yes this is a possible reason. As this seems to be no longer the case, I can’t confirm. Feel free to answer to this post in case you see again this behavior.
