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
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] [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
