GPU clock resetting at cleanup can interfere with other processes - Redmine #1970

The NVML-based clock adjustment implementation resets the clocks at cleanu This can result in interfering with other jobs that mdrun shares a GPU with. While it should not be very common that multiple processes share a node and a/some GPU (s) and the admins set up the NVIDIA driver to allow user-adjustable application clocks, it can still be irritating if a user manages the machine themselves, sets the applciation clocks manually while mdrun is running e.g. for another process that’s triggered after mdrun finishes just to have the clocks reset by mdrun before exit.

This is categorized under the “bug” tracker given that this is a possibly undesirable side-effect of the application-clock support. However, ATM I don’t see much that we can do about it other than (possibly) improving user-facing notes + documentation).
