LivermoreLoops

Sac implementations of the Livermore Loop benchmarks

Building programs require operational sac2c and sac4c as well as CMake at least version 3.3.

Building instructions:

$ cd LivermoreLoops
$ git submodule init
$ git submodule update
$ mkdir build
$ cd build
$ cmake ..
$ make -j5
$ ctest -j N

Compiled files will be available in the build directory, under corresponding sub-directories. Each directory will be built for seq and mt_pth targets, appending the name of the target to the name of the directory.

Performance and unit tests are available with ctest. The value N is the number of threads ctest will execute concurrently. Unlike make -j, N must be specified, or its value is assumed to be 1.
