1. Prerequisites:
===================
Make sure you have the latest Intel ipcx release loaded (via modules or similar)
Make sure you have SYCL aware MPICH or Intel MPI loaded (assumed as mpicxx)

2. Obtain Grid:
===================

bash$
git clone https://github.com/paboyle/Grid
cd Grid
./bootstrap.sh
cd systems/PVC

3. Build Grid:
===================

Here, configure command is stored in file config-command:

bash$
../../configure \
	--enable-simd=GPU \
	--enable-gen-simd-width=64 \
	--enable-comms=mpi-auto \
	--enable-accelerator-cshift \
	--disable-gparity \
	--disable-fermion-reps \
	--enable-shm=nvlink \
	--enable-accelerator=sycl \
	--enable-unified=no \
	MPICXX=mpicxx \
	CXX=icpx \
	LDFLAGS="-fiopenmp  -fsycl -fsycl-device-code-split=per_kernel -fsycl-device-lib=all -lze_loader " \
	CXXFLAGS="-fiopenmp -fsycl-unnamed-lambda -fsycl -Wno-tautological-compare "

make all

4. Run a benchmark:
===================

*** Assumes interactive access to node. ***

run Benchmark_dwf_fp32 using benchmarks/bench.sh

bash$
cd benchmarks
./bench.sh
