[gmx-developers] Please cancel outdated CI pipelines

[Erik Lindahl]

PS:

Note that there are two settings: The *request* you set for CPU and memory
is guaranteed when you execute (although we count each hardware thread as a
CPU), while the limit is something you ask for, but aren't guaranteed.

Cheers,

Erik
