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/Utils/WarpXMovingWindow.cpp | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'Source/Utils/WarpXMovingWindow.cpp') diff --git a/Source/Utils/WarpXMovingWindow.cpp b/Source/Utils/WarpXMovingWindow.cpp index 9b270469c..a95b58a41 100644 --- a/Source/Utils/WarpXMovingWindow.cpp +++ b/Source/Utils/WarpXMovingWindow.cpp @@ -10,6 +10,7 @@ #include "BoundaryConditions/PML.H" #include "Particles/MultiParticleContainer.H" +#include "Parallelization/WarpXCommUtil.H" #include "Utils/WarpXConst.H" #include "Utils/WarpXProfilerWrapper.H" @@ -292,7 +293,7 @@ WarpX::shiftMF (MultiFab& mf, const Geometry& geom, int num_shift, int dir, if ( WarpX::safe_guard_cells ) { // Fill guard cells. - tmpmf.FillBoundary(geom.periodicity()); + WarpXCommUtil::FillBoundary(tmpmf, geom.periodicity()); } else { IntVect ng_mw = IntVect::TheUnitVector(); // Enough guard cells in the MW direction @@ -300,7 +301,7 @@ WarpX::shiftMF (MultiFab& mf, const Geometry& geom, int num_shift, int dir, // Make sure we don't exceed number of guard cells allocated ng_mw = ng_mw.min(ng); // Fill guard cells. - tmpmf.FillBoundary(ng_mw, geom.periodicity()); + WarpXCommUtil::FillBoundary(tmpmf, ng_mw, geom.periodicity()); } // Make a box that covers the region that the window moved into -- cgit v1.2.3
