The standard core hours were introduced to treat systems of different age on equal footing. Modern systems have more powerful processors, more work can be done in one WCH compared to legacy systems. @@ -156,3 +158,5 @@ Password: OPEN-0-0 1500000 400644 225265 1099356 DD-13-1 10000 2606 2606 7394 ``` + +---8<--- "mathjax.md" -- GitLab
