Files
file	clfftinitializer.cpp
file	clfftinitializer.h
	Declares ClfftInitializer class, which initializes and tears down the clFFT library resources in OpenCL builds, and does nothing in other builds, and a factory function for it.
file	device_context.cpp
file	device_context.h
	Declarations for DeviceContext class.
file	device_context_ocl.cpp
file	device_context_sycl.cpp
file	device_event.h
	Declares DeviceEvent for all build configuraitons.
file	device_event_ocl.h
	Implements a DeviceEvent class for OpenCL.
file	device_event_sycl.h
	Implements a GpuEventSynchronizer class for SYCL.
file	device_stream.cpp
file	device_stream.h
	Declarations for DeviceStream class.
file	device_stream_manager.cpp
file	device_stream_manager.h
	This file declares a manager of GPU context and streams needed for running workloads on GPUs.
file	device_stream_ocl.cpp
file	device_stream_sycl.cpp
file	devicebuffer.h
	Implements the logic for handling of DeviceBuffer types in OpenCL, CUDA and SYCL.
file	devicebuffer_datatype.h
	Declares the DeviceBuffer data type.
file	devicebuffer_ocl.h
	Implements the DeviceBuffer type and routines for OpenCL. Should only be included directly by the main DeviceBuffer file devicebuffer.h. TODO: the intent is for DeviceBuffer to become a class.
file	devicebuffer_sycl.cpp
file	devicebuffer_sycl.h
	Implements the DeviceBuffer type and routines for SYCL. Should only be included directly by the main DeviceBuffer file devicebuffer.h. TODO: the intent is for DeviceBuffer to become a class.
file	gmxopencl.h
	Wraps the complexity of including OpenCL in Gromacs.
file	gmxsycl.h
	Wraps the complexity of including SYCL in GROMACS.
file	gpu_macros.h
file	gpu_utils.cpp
file	gpu_utils.h
	Declare functions for detection and initialization for GPU devices.
file	gpueventsynchronizer.h
	Implements a GpuEventSynchronizer class.
file	gpuregiontimer.h
	Defines the GPU region timer implementation/wrapper classes. The implementations live in gpuregiontimer.cuh for CUDA and gpuregiontimer_ocl.h for OpenCL.
file	gpuregiontimer_ocl.h
	Implements the GPU region timer for OpenCL.
file	gpuregiontimer_sycl.h
	Implements the GPU region timer for SYCL.
file	gputraits.h
	Declares the GPU type traits for non-GPU builds.
file	gputraits_ocl.h
	Declares the OpenCL type traits.
file	gputraits_sycl.h
	Declares the SYCL type traits.
file	hostallocator.cpp
file	hostallocator.h
	Declares gmx::HostAllocationPolicy, gmx::HostAllocator, gmx::HostVector and gmx::PaddedHostVector, which are used to make/be standard library containers that can allocate memory suitable for transfers. Currently the only supported transfers using pinned memory are to CUDA GPUs, but other possibilities exist in future.
file	ocl_caching.cpp
file	ocl_caching.h
file	ocl_compiler.cpp
file	ocl_compiler.h

file	oclutils.cpp
file	oclutils.h
	Declare utility routines for OpenCL.
file	pinning.h
	Declares functions for pinning memory to be suitable for efficient GPU transfers on CUDA.
file	pmalloc.h
	Declare functions for host-side memory handling.
file	pmalloc_ocl.cpp
file	pmalloc_sycl.cpp
file	sycl_kernel_utils.h
	SYCL kernel helper functions.
file	syclutils.h
	Declare utility routines for SYCL.
