 Instead, it seeks to define a single, unified, and stable layer in the C++ Standard Library. Applications, libraries, and programming models (such as SYCL [[3]][sycl-1-2-1], Kokkos [[19]][kokkos], HPX [[13]][hpx] or TBB [[12]][tbb]) can build on this layer; hardware vendors can support it via standards such as OpenCL [[4]][opencl-2-2], CUDA [[20]][cuda], OpenMP [[6]][openmp-5], MPI [[16]][mpi], Hwloc [[2]][hwloc], HSA [[5]][HSA] and HMM [[21]][hmm]; and it can be extended when necessary.
 
-This layer will not be characterized in terms of specific categories of hardware such as CPUs, GPUs and FPGAs as these are broad concepts that are subject to change over time and have no foundation in the C++ machine model. It will instead define a number of abstract properties, which reflect an architecture's properties.
+This layer will not be characterized in terms of specific categories of hardware such as CPUs, GPUs and FPGAs as these are broad concepts that are subject to change over time and have no foundation in the C++ machine model. It will instead define a number of abstract properties of system architectures that are not tied to any specific hardward.
 
 The initial set of properties that this paper would propose be defined in the C++ standard library would reflect a generalization of the observable behaviors, capabilities and limitations of common architectures available in heterogeneous and distributed systems today. However the intention is that the interface be extensible so that that vendors can provide their own extensions to provide visibility into the more niche characteristics of certain architectures.
