Dependencies

You would need to download and install the following components for using AVX and NVIDIA GPUs to speed up your programs

• Intel OpenCL SDK for Linux from software.intel.com/sdk/opencl. Follow the installation instructions (no special requirements).
• CUDA

Build

# Get dependencies
cd llvm/projects
git clone https://github.com/llvm-mirror/compiler-rt
git checkout release_40
cd ../..

Switch to 4.0 branch

git checkout update_llvm4

Build hpvm

mkdir install
mkdir build && cd build
cmake ../llvm -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" -DCMAKE_INSTALL_PREFIX=../install
make -j<number of threads you want to use to build hpvm>

Build hpvm runtime

cd projects/visc-rt
make
cd ..

To use hpvm to compile benchmarks set environment variable LLVM_SRC_ROOT to llvm directory in your local repository

export LLVM_SRC_ROOT=<full path to hpvm>/llvm

Benchmark Suites

Benchmark suites have been migrated to the LLVM 4.0 build. They are located in VISC.

Running an example (sgemm in parboil)

cd llvm/test/VISC/parboil/benchmarks/sgemm
make 
make run
