#include <gromacs/ewald/pme-gpu-types-host-impl.h>
The main PME CUDA/OpenCL-specific host data structure, included in the PME GPU structure by the archSpecific pointer.
Public Attributes | |
CommandStream | pmeStream |
The GPU stream where everything related to the PME happens. | |
Context | context |
A handle to the GPU context. TODO: this is currently extracted from the implementation of pmeGpu->programHandle_, but should be a constructor parameter to PmeGpu, as well as PmeGpuProgram, managed by high-level code. | |
GpuEventSynchronizer | syncSpreadGridD2H |
Triggered after the grid has been copied to the host (after the spreading stage). | |
bool | performOutOfPlaceFFT |
A boolean which tells whether the complex and real grids for cu/clFFT are different or same. Currenty true. | |
bool | useTiming |
A boolean which tells if the GPU timing events are enabled. False by default, can be enabled by setting the environment variable GMX_ENABLE_GPU_TIMING. Note: will not be reliable when multiple GPU tasks are running concurrently on the same device context, as CUDA events on multiple streams are untrustworthy. | |
std::vector< std::unique_ptr < GpuParallel3dFft > > | fftSetup |
Vector of FFT setups. | |
std::array< GpuRegionTimer, gtPME_EVENT_COUNT > | timingEvents |
All the timers one might use. | |
std::set< size_t > | activeTimers |
Indices of timingEvents actually used. | |
