Description

Wraps the complexity of including SYCL in GROMACS.

The __SYCL_COMPILER_VERSION macro is used to identify Intel DPCPP compiler. See https://github.com/intel/llvm/pull/2998 for better proposal.

Intel SYCL headers use symbol DIM as a template parameter, which gets broken by macro DIM defined in gromacs/math/vectypes.h. Here, we include the SYCL header while temporary undefining this macro. See https://github.com/intel/llvm/issues/2981.

Different compilers, at the time of writing, have different names for some of the proposed features of the SYCL2020 standard. For uniformity, they are all aliased in our custom sycl_2020 namespace.
