SYCL-Bench

SYCL Benchmark Suite, work in progress

Benchmarks support the following command line arguments:

  • --size=<problem-size> - total problem size. For most benchmarks, global range of work items. Default: 3072
  • --local=<local-size> - local size/work group size, if applicable. Not all benchmarks use this. Default: 256
  • --num-runs=<N> - the number of times that the problem should be run, e.g. for averaging runtimes. Default: 5
  • --device=<d> - changes the SYCL device selector that is used. Supported values: cpu, gpu, default. Default: default
  • --output=<output> - Specify where to store the output and how to format. If <output>=stdio, results are printed to standard output. For any other value, <output> is interpreted as a file where the output will be saved in csv format.
  • --verification-begin=<x,y,z> - Specify the start of the 3D range that should be used for verifying results. Note: Most benchmarks do not implement this feature. Default: 0,0,0
  • --verification-range=<x,y,z> - Specify the size of the 3D range that should be used for verifying results. Note: Most benchmarks do not implement this feature. Default: 1,1,1
  • --no-verification - disable verification entirely
  • --no-ndrange-kernels - do not run kernels based on ndrange parallel for
  • --warmup-run - run benchmarks once before evaluation to discard possible "warmup" times, e.g., JIT compilation

Usage

Clone sycl-bench repo

$ git clone https://github.com/bcosenza/sycl-bench.git

Navigate into repo and create build folder

$ cd bench
$ mkdir build && cd build

Compile with CMake

$ cmake -DSYCL_IMPL=[target SYCL implementation] [-DSYCL_BENCH_HAS_FP64_SUPPORT=ON|OFF] [other compiler arguments] ..
$ cmake --build .
$ sudo make install

Example compiling with CMake for DPC++:

$ cmake -DSYCL_IMPL=LLVM -DCMAKE_CXX_COMPILER=/path/to/llvm/build/bin/clang++ ..

Each test should now have an executable in the build folder Run individual tests as such:

$ ./arith --device=cpu --output=output.csv

Packaging

SYCL-Bench provides a CMake target package (and package_source) to package a SYCL-Bench installation. Users can configure what generators to use to build the packages by passing a semicolon-separated list of generators to use to the CPACK_GENERATOR CMake flag and then build the enabled packages by building the package target:

cmake -Bbuild -DCPACK_GENERATOR="TGZ;ZIP"
cmake --build build --target package

For more information, check the CPack documentation for the relevant CMake version.

Packages built via the package target will contain all files contained in a SYCL-Bench installation (binaries, scripts, benchmark inputs). Packages built via the package_source target will additionally contain the source files.
