- Quick fix https://gerrit.gromacs.org/#/c/gromacs/+/13801/
- 04:45 PM GROMACS Revision a73c3ec2: Remove excessive H2D and D2H coordinates copies when update is offloaded
- The H2D copies are only needed:
1. When update is not ofloaded.
2. At the search steps, after device buffers were rei...
- 02:28 PM GROMACS Feature #3162 (New): Add virtual site support to GPU version of update-constraints.
- The virtual sites require forces to be distributed among normal atoms. Hence, all forces has to be copied to the host...
