+
+2. Obtain Grid:
+===================
+
+bash$

+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 \

+4. Run a benchmark:
+===================
+
+*** Assumes interactive access to node. ***
+
+run Benchmark_dwf_fp32 using benchmarks/bench.sh
+
