microSYCL

This is a micro-benchmark for testing the overhead of SYCL features, the following features are tested in this benchmark

• memory allocation
• parallelization
• atomics
• barriers
• vectorization
• memory access patterns

Building

Make is used to build this benchmark.

cd microSYCL
mkdir -p bin
make SYCL_IMPL=oneapi|intel-llvm|<empty=acpp> BACKEND=omp|<empty=ocl> ARCH=x86|a64fx|graviton3

Depending on the Implementation choosen, paths to all the the binaries and libraries should be added to the standard environment variables, such as $PATH and $LD_LIBRARY_PATH

For optimal performance OMP_PROC_BIND environment variable is set to true. This is applicable only when using OpenMP backend.
