+### SYCL
+
+This section shows how to compile SYCL codes using the Intel compiler. First,
+load the following modules:
+
+    module load gcc/10.2.0 nvidia/nvhpc/22.11
+    module load oneapi
+    module load compiler
+
+Once the above modules are loaded, you can compile the code using the following:
+
+    icpx -fsycl code.cpp
+
+For testing, you can use material from the [SYCL Academy repository](https://github.com/codeplaysoftware/syclacademy).
