+# The Bandwidth Benchmark
+
+This is a collection of simple streaming kernels for teaching purposes.
+It is heavily inspired by John McCalpin's [https://www.cs.virginia.edu/stream/ stream benchmark].
+
+## Build
+
+1. Configure the toolchain to use in the `Makefile`:
+```
+TAG = GCC  # Supported GCC, CLANG, ICC
+```
+
+2. Review the flags for toolchain in the corresponding included file, e.g. `include_GCC.mk`. OpenMP is disabled per default, you can enable it by uncommenting the OpenMP flag:
+```
+OPENMP   = -fopenmp
+```
+
+3. Build with:
+```
+make
+```
+
+You can build multiple toolchains in the same directory, but notice that the Makefile is only acting on the one currently set.
+Intermediate build results are located in the `<TOOLCHAIN>` directory.
+
+4. Clean up with:
+```
+make clean
+```
+to clean intermediate build results.
+
+```
+make distclean
+```
+to clean intermediate build results and binary.
+
+5. (Optional) Generate assembler files:
+```
+make asm
+```
+The assembler files will also be located in the `<TOOLCHAIN>` directory.
