Conjugate_Gradient

This benchmark implements different versions of the Conjugate Gradient (CG) algorithm using various features of SYCL.

Building

CMake is used to build this benchmark.

mkdir build && cd build
cmake .. -DSYCL_COMPILE= DPCPP|HIPSYCL -DOMP_COMPILE=true|false
make

if HIPSYCL is chosen as a SYCL implementation then -DHIPSYCL_INSTALL_DIR need to be specified. Similarly, when OMP_COMPILE is true then OMP_LIBRARY need to be specified.

For optimal performance OMP_PROC_BIND is set to true.

Example

./binary 
   -s <problem size>
   -b <block size (optional)>
   -a <atomics (yes or no) initialized with yes>
