      Optimize PME spread charge kernel (#4633) · 8ea42950
      Anton Gorenko authored
      * PME_ORDER threads process one atom;
      * PME_ORDER threads access consecutive addresses;
      * No need to permute z indices with zindexTable;
      * finishSpreadCharge is needed only with fixed point charge spreading;

      Cleanup Cmake scripts for HIP platform · aca24d5f
      Anton Gorenko authored
      * Remove setting of link libraries, include and link dirs and compile
        flags for each target, instead let Cmake deal with them by linking the
        main library to hip::host hiprtc::hiprtc hip::hipfft;
      * Fix: custom command without ADD_CUSTOM_TARGET and ADD_DEPENDENCIES is
        executed for both static and shared targets;
      * Remove IF(APPLE) parts.

      Fix SegFault in HipCalcHippoNonbondedForceKernel
      
          HipSort was created using a temporary ref. Adding `HipContext& cu`
          field to HipCalcHippoNonbondedForceKernel fixes the issue;

      Final HIP Platform implementation for AMD GPUs on ROCm (#3338) · a39fa14a
      Adel Johar authored
      
      
      * Support kernel files with extensions of any length (like .hip)
      
      * Do not allow to replace symbols in single-line comments
      
      * Add OPENMM_BUILD_COMMON CMake option
      
      It allows to build and install common platform files even if
      CUDA or OpenCL platforms are not built.
      This is required for HIP platform (openmm-hip) if ROCm OpenCL
      packages are not installed.
      
      * Add an option for Python wrapper to install into user packages
      
      OPENMM_PYTHON_USER_INSTALL is OFF be default.
      
      * Support FFT backends in Amoeba plugin
      
      The HIP platform supports FFT backends, this commit moves
      findLegalFFTDimension to ComputeContext, so platforms can have their own
      implementations.
      
      * Compatibility for common platform w/ new HIP platform
      
      * Do not use volatile with private and local AtomData parameters on HIP
      
      The generated code is not optimal, for example, the compiler generates
      flat_load instructions instead of ds_read.
      
      * Tune launch bounds for PME grid-related kernels and add WA for RDNA
      
      Force the compiler to use all registers for gridSpreadCharge and
      gridInterpolateForce by limiting max waves per EU to 1 on CDNA GPUs,
      RDNA GPUs work better without it.
      
      * Optimize atom data structs in GBSA and Amoeba on HIP
      
      Manually rearrange fields, add paddings and force alignments to
      have faster accesses to shared memory: ds_read and ds_write may
      work slower if addresses are not aligned by 16 bytes.
