From 2bc1322aa76f7026e5b42639bb3d12125da2407c Mon Sep 17 00:00:00 2001 From: Andrew Myers Date: Mon, 18 Oct 2021 14:06:08 -0700 Subject: Option to do single precision mesh communication. (#2294) * option to use single precision guard cell exhanges * add missing files * fix namespace issue * change precision of comms to float * ParmParse the single_precision_comms flag * set back to real * test * make sure dst is filled * nGrow -> nGrowVect * restore float * don't override valid cells * single precision mesh * whitespace * wrap SumBoundary * Wrap additional uses of FillBoundary. * catch missing copies of ParallelCopy * missing OverrideSyncs * add wrapper for iMultifab * fix typo * moar typos * typo * strip single_precision_mesh option * fix original copy * update fusible syntax Co-authored-by: Weiqun Zhang * Fix: Single Precision Builds Should not copy around data for `do_single_precision_comms` * Docs: warpx.do_single_precision_comms * initialize this tmp multifab to 0.0 * fix tiny profile label * remove orig copies, they are only correct for FillBoundary * loosen tolerance for space charge tests for single precision * missing some setVal * another missing setVal * missing setVal * add wrapper for new version of sumboundary * add explicit cast to silence compiler warning * add a test for single precision comms * revert change to test precision * add benchmark for single precision comms test * restore tolerance I removed by mistake * tolerance * copyright headers * drop tolerance for single precision tests in default analysis script * missing python module * bump tol again * fix bad merge * Apply suggestions from code review Co-authored-by: Axel Huebl Co-authored-by: Remi Lehe Co-authored-by: Axel Huebl Co-authored-by: Weiqun Zhang --- Source/Particles/MultiParticleContainer.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'Source/Particles/MultiParticleContainer.cpp') diff --git a/Source/Particles/MultiParticleContainer.cpp b/Source/Particles/MultiParticleContainer.cpp index ea8e58ee7..6cf890821 100644 --- a/Source/Particles/MultiParticleContainer.cpp +++ b/Source/Particles/MultiParticleContainer.cpp @@ -10,6 +10,7 @@ * License: BSD-3-Clause-LBNL */ #include "MultiParticleContainer.H" +#include "Parallelization/WarpXCommUtil.H" #include "Particles/ElementaryProcess/Ionization.H" #ifdef WARPX_QED # include "Particles/ElementaryProcess/QEDInternals/BreitWheelerEngineWrapper.H" @@ -556,7 +557,7 @@ MultiParticleContainer::GetChargeDensity (int lev, bool local) } if (!local) { const Geometry& gm = allcontainers[0]->Geom(lev); - rho->SumBoundary(gm.periodicity()); + WarpXCommUtil::SumBoundary(*rho, gm.periodicity()); } return rho; } -- cgit v1.2.3
