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

Configure the toolchain to use in the Makefile:

TAG = GCC  # Supported GCC, CLANG, ICC

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

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.

Clean up with:

make clean

to clean intermediate build results.

make distclean

to clean intermediate build results and binary.

(Optional) Generate assembler files:

make asm

The assembler files will also be located in the <TOOLCHAIN> directory.
