12:05 AM GROMACS Revision 85b8ed21: Add and enable PME OpenCL
PME OpenCL kernels (spread, gather, solve) are added.
PmeGpuContext is taught to compile them. PME with OpenCL
is ena...

12:31 PM GROMACS Revision bfeace90: Prepare pme-gpu-types.h for OpenCL
DeviceBuffer fields are hidden from the future OpenCL
device compilation with a macro. Struct fields are reordered
to...

05:53 PM GROMACS Revision dee2ffc7: Remove hardcoded warp_size == 32 assumption from PME GPU
The PME OpenCL host code now queries the warp_size aka max
execution width from the device. The CUDA/unit test handli...

03:12 PM GROMACS Revision efc5b167: Move vectype_ops.clh into gpu_utils
OpenCL compilation now uses gpu_utils as an include directory in source.
All the OpenCL sources are still installed i...

08:44 AM GROMACS Revision abb0e3c6: Ensure PME with OpenCL does not attempt to pin
Host-only memory pinning was designed with CUDA in mind, while OpenCL
requires managing both host and device memory b...
