Software artifacts for Euro-Par 2018 paper: "Efficient Strict-Binning Particle-in-Cell Algorithm for Multi-Core SIMD Processors"

This dataset contains artifacts relating to the results presented in the Euro-Par 2018 conference paper entitled "Efficient Strict-Binning Particle-in-Cell Algorithm for Multi-Core SIMD Processors".<br>The paper describes a multi-core PIC algorithm that achieves close-to-minimal number of memory transfers with the main memory, while at the same time exploiting SIMD instructions for numerical computations and exhibiting a high degree of OpenMP-level parallelism.<br>A README file titled Overview_document.pdf outlines the purpose and dependencies of the software, as well as instructions for compiling and running it.<br>The processes used to demonstrate the performance, validation and verification of the software are also described.<br>This artifact is composed of several folders:<br># include and src contain all the modular code for Pic-Vert (as .h and .c files). By opening them, it is possible to check that we implemented the data structures we describe in thepaper:– compiler_test.h: compiler check to know which features we can use.– diagnostics.c/h: electric field diagnostics.– fields.c/h: data structure for the electric fields.– hdf5_io.c/h: handling of HDF5 outputs.– initial_distributions.c/h: possible initial distributions of particles.– math_functions.h: useful mathematical functions not already in standard libraries.– matrix_functions.c/h: dynamic allocation of arrays.– meshes.c/h: data structure for the grid.– output.c/h: handling of outputs other than HDF5.– papi_handlers.c/h: handling of PAPI performance counters.– parameter_reader.c/h: reading parameter files for simulations.– parameters.h: useful parameters (architecture, mathematics, simulation. . . )– particle_type_concurrent_chunkbags_of_soa_XXX.c/h: data structure for particles.– poisson_solvers.c/h: data structure for the FFT Poisson solver.– random.c/h: pseudo-random number generators available.– rho.c/h: data structure for the charge density.– space_filling_curves.c/h: use of space-filling curves in the code.– variadic.h: allows to write function with default arguments in C.# simulations contains the PIC simulations that we used for this article, and that uses the files in the previous point.# scripts contains the compile and run scripts for our simulations.# memory contains spread sheets to compute the number of particles you should put in the simulation, given your architecture (prior to compilation).# Stream-test contains the Stream benchmark# post-process contains scripts to “automate data extraction and the production of plots”.# sample-outputs contains “files that represent expected outputs”.<br>
