11:15 AM GROMACS Revision 9b682479: Disable GPU update/constraints when neither PME nor buffer ops are offloaded.
Using the GPU-version of update makes sense if forces are already on the GPU,
i.e. if at least:
1. PME is on the GPU ...

11:04 PM GROMACS Revision 62abb664: Fix for the post-submit failure
Commit 21abdb3 introduced several "unused variable" warning
in the post-submit matrix. This fixes the issue.
Change-...
10:53 PM GROMACS Revision 873bf080: Decouple GPU force buffer management from buffer ops in NBNXM

To make transition to the new device-side state propagator data
manager easier, the copy and plain buffers management...
06:35 PM GROMACS Revision 21abdb3c: Reorganize PME code:
1. Split H2D copy and spread launch
2. Add getter for the padding, required in coordinates buffer
3. Add the getter f...
