* 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.
