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.
Building Simit
To build Simit you must install CMake 2.8.3 or later and LLVM 3.4.2. See http://www.cmake.org/cmake/resources/software.html for a copy of CMake. If your system does not have packages for LLVM you can download it at http://llvm.org/releases/download.html. 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_34/ llvm-3.4.2
Then build it:
cd llvm-3.4.2
./configure --disable-terminfo --enable-optimized --enable-assertions --enable-targets=x86
make -j8
Then set the LLVM_CONFIG environment variable to point to llvm-config:
export LLVM_CONFIG=<path to llvm>/Release+Asserts/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):
cd <simit-directory>
./build/bin/simit-test
To check a Simit program do:
cd <simit-directory>
./build/bin/simit-check <simit-program>
For example:
./build/bin/simit-check examples/springs.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 do:
cd <simit-directory>
doxygen
This will create a doc directory containing HTML documentation. Open doc/index.html in your browser.
Simit Continuous Testing
Simit is currently tested on a Jenkins instance located at builds.simit-lang.org . A test build is triggered on every push to master and each pull request. The status of the test is marked on the pull request in Github.
