3 Known issues relevant for developers
4 ====================================
6 This is a non-exhaustive list of known issues that have been observed
7 and can be of interest for developers. These have not been solved
8 because they are either outside the scope of the GROMACS project
9 or are are simply too difficult or tedious to address ourselves.
11 Issues with GPU timer with OpenCL
12 ---------------------------------
14 When building using OpenCL in ``Debug`` mode, it can happen that the GPU timer state gets
15 corrupted, leading to an assertion failure during the :ref:`mdrun <gmx mdrun>`.
16 This seems to be related to the load of other, unrelated tasks on the GPU.
18 GPU emulation does not work
19 ---------------------------
21 The non-bonded GPU emulation mode does not work, at least for builds
22 with GPU support; then a GPU setup call is called.
23 Also dynamic pruning needs to be implemented for GPU emulation.
