-# Heterogeneous Parallel Virtual Machine
-
-This repository contains miscellaneous supporting materals for HPVM.

-[Technical Report](https://arxiv.org/abs/1611.00860)
-
-## 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](software.intel.com/sdk/opencl). Follow the installation instructions (no special requirements).
-* CUDA
-
-## Build
-
-Switch to hpvm-dev
-```shell
-git checkout hpvm-dev
-```
-
-Build hpvm
-```shell
-mkdir install
-mkdir build && cd build
-cmake ../llvm -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_INSTALL_PREFIX=../install
-make -j<number of threads you want to use to build hpvm>
-```
-
-Build hpvm runtime 
-```shell
-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
-```shell
-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](/llvm/test/VISC/parboil/benchmarks).
-
-### Running an example (sgemm in parboil)
-```shell
-cd llvm/test/VISC/parboil/benchmarks/sgemm
-make 
-make run
-```
-
-### Other Old Components
-
-Search this repository for "visc", case-insensitive.
