Experiments

We can compare the performance of the SYCL, DPCT-generated, and OpenMP implementations of each program on Intel integrated GPUs. The performance results below were obtained with the Intel OpenCL intercept layer. "total enqueue" indicates the total number of low-level OpenCL enqueue commands called by a parallel program. These enqueue commands include "clEnqueueNDRangeKernel", "clEnqueueReadBuffer", and "clEnqueueWriteBuffer". The host timing is the total elapsed time of executing OpenCL API functions on a CPU host while the device timing is the total elapsed time of executing OpenCL API functions on a GPU device. The Plugin Interface is OpenCL.

Setup

Software: Intel® oneAPI Beta08* Toolkit, Ubuntu 18.04
Platform 1: Intel® Xeon E3-1284L with a Gen8 P6300 integrated GPU
Platform 2: Intel® Xeon E-2176G with a Gen9.5 UHD630 integrated GPU

*newer versions may be used when they can produce results correctly

Note

We may execute SYCL programs on an Nvidia GPU by building the software from source with support for Nvidia CUDA. Then, go to a directory (e.g., affine-sycl) and type the command " make -f Makefile.cuda run". "Makefile.cuda" may be modified for different versions of Nvidia GPUs and toolchains.

We may execute SYCL programs on an AMD GPU by building the software from source with support for AMD HIP. Then, go to a directory (e.g., affine-sycl) and type the command " make -f Makefile.hip run". "Makefile.hip" may be modified for different versions of AMD GPUs and toolchains.

We may execute HIP programs on an Intel GPU by building the software from source with support for OpenCL. Then, go to a directory (e.g., affine-hip) and type the command " make -f Makefile.hipcl run". "Makefile.hipcl" may be modified for different versions of AMD GPUs and toolchains.

We may also evaluate OpenMP Offload to GPU feature with AOMP on an AMD GPU or the Nvidia HPC SDK on an Nvidia GPU. Then, go to a directory (e.g., affine-omp) and type "make -f Makefile.aomp run" or "make -f Makefile.nvc run". Both files may be modified for different versions of GPUs and toolchains.

Run

A script "run.sh" attempts to run all tests with the OpenCL plugin interface. To run a single test, go to a test directory and type the command "make run".
