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.
