DynVec-artifact

Implementation and evaluation scripts for DynVec

Pre-requests

• Intel oneAPI 2021.1 (other version is not tested)

Code structure

• DynVec-motivation includes the gather/scatter micro-benchmarks for motivating performance evalutions;
• scripts includes the build/run tooling scripts to build/run all artifacts including ICC, DynVec, MKL, CSR5, and DynVec motivtions;
• spmv/Benchmark_SpMV_using_CSR5 is the implementations for CSR5 (as a submodule);
• spmv/CVR is the implementations for CVR on AVX512 platforms (as a submodule);
• spmv/spmv_mkl contains the source codes to implement SpMV with MKL;
• spmv/DynVec contains the DynVec source codes.
• data.tar.gz can be downloaded from here and it will be used in run.sh for SpMV evaluation.

Build

First, we need to clone the entire repo with compared CSR5 submodule:

git clone --recursive https://github.com/buaa-hipo/DynVec-artifact.git

After cloning the repo, use the build script to build the dependency, DynVec, CSR5 and motivation benchmarks:

./build.sh <knl,avx2,avx512>

Note that the build script will download and compiles llvm-8.0.0, which may take some time to finish.

Running SpMV

To run spmv with prepared dataset (data.tar.gz in release), we just need to use the run script:

./run.sh

The results are stored in log/run_log/spmv/log_spmv_*.
