Simit is a new programming language designed to make it easy to write high-performance code to compute on sparse systems. For more information see simit-lang.org.

To build Simit you must install CMake 2.8.3 or greater and LLVM 3.7 or greater. You must then make sure llvm-config is available in your path.

If you want to build LLVM yourself you can check it out using SVN:

svn co https://llvm.org/svn/llvm-project/llvm/branches/release_37 llvm3.7

then build it:

cd llvm3.7
mkdir build
cd build
cmake -DLLVM_ENABLE_TERMINFO=OFF -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_RTTI=ON -DCMAKE_BUILD_TYPE=Release ..
make -j8

then point Simit to it:

export LLVM_CONFIG=<path to llvm>/build/bin/llvm-config

To perform an out-of-tree build of Simit do:

cd <simit-directory>
mkdir build
cd build
cmake ..
make -j8

To run the test suite do (all tests should pass, but ignore disabled tests):

cd <simit-directory>
./build/bin/simit-test

To check a Simit program:

cd <simit-directory>
./build/bin/simit-check <simit-program>

For example:

./build/bin/simit-check apps/springs/isprings.sim

To make the Simit bin directory part of your PATH:

cd <simit-directory>
export PATH="$PATH:`pwd`/build/bin"

To build Simit's documentation:

cd <simit-directory>
doxygen

This will create a doc directory containing HTML documentation. Open doc/index.html in your browser.
