iSALE3D-prototype

This software was developed as part of Lorenzo Paganelli's ACSE-9 project. The aim of such project is to improve the parallel performance of iSALE3D, a well-established shock physics code. This software, which emulates some portions of interest of iSALE3D, was developed to investigate more easily the benefits and drawbacks of potential optimisation strategies.

Repository structure

• source code is located in src and include directories. src/benchmark.cpp contains the entry point of the program and a brief description of the code structure. Instructions on how to compile and run the code are on top of src/benchmark.cpp.
• test.sh is a simple script that runs the code multiple times with all the available options and checks the exit statuses. The script is designed to be used jointly with the DEBUG_MODE. When the code is compiled in debug mode (i.e., with -DDEBUG_MODE flag), extra checks are performed to ensure correct execution. If any check fails, test.sh will stop and warn the user.
• jobs contains the results of various runs of the software on DiaL.

Enviroments

The code was developed and tested on MacOS 10.15.7 (19H2) with gcc 7.5.0 and Open MPI 4.1.1. It was deployed on CentOS Linux 7 with:

• gcc 6.4 and Open MPI 3.0.1
• mpiicc (i.e., Intel compiler and MPI implementation) version 2021.2.0
• mpiicc version 17.0.4
