paqr_SC22

Artifact Description / Article Evaluation for SC22

Four components are present to reproduce the results in the paper.

1. paqr_matlab.tar.gz
2. docker wissamsid/paqr_lapack
3. docker abdelfattah83/paqr_batch_cuda:latest
4. paqr_scalapack.tar.gz

1) MATLAB

In order to reproduce MATLAB results.

tar xz paqr_matlab.tar.gz
cd matlab/src
matlab
>>> test(100);

The "100" should be replaced by "1000" to get results of Table1.

NOTE: The version of MATLAB used is R2020a Update 2 (9.8.0.1380330) 64-bit (glnxa64).

2) LAPACK

docker pull wissamsid/paqr_lapack
docker run -it --entrypoint=bash --privileged --userns=host wissamsid/paqr_lapack
sh test_paqr_lapack.sh 100 100

In order to reproduce the results of Table2, replace "100 100" by "10000 10000".

NOTE: The version of LAPACK used is 3.10.0.

3) MAGMA

In order to reproduce the results of Table3, run the following:

docker pull abdelfattah83/paqr_batch_cuda:latest
docker run -it --entrypoint=bash --privileged --userns=host abdelfattah83/paqr_batch_cuda:latest
sh test_paqr_batch.sh

NOTE: The MAGMA version used is 2.5.0.

4) ScaLAPACK

The following "module load" are examples only. This only highlights that cmake, MKL and Open-MPI should be present in the environment.

tar xzf paqr_scalapack.tar.gz
module load cmake intel-oneapi-mkl openmpi
cd scalapack
bash test.sh

The five results lines correspond to: warmup QR 1, warmup QR 2, QR, PAQR, QRCP.

NOTE: The ScaLAPACK version used is 2.2.

Appendix) Software stack for LAPACK and ScaLAPACK

The ScaLAPACK code was compiled with:

• GCC/10.2.0
• Intel-oneapi-MKL/2022.0.2
• Open-MPI/4.1.2
• cmake/3.22.2

paqr_sc22's Issues

paqr_lapack

Hello,

I am particularly interested in your work. May I ask if you can open source the code for paqr_lapack_tar.gz?
