2021-10-18Option to do single precision mesh communication. (#2294)Gravatar Andrew Myers 1-0/+243
* 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 <WeiqunZhang@lbl.gov> * 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 <axel.huebl@plasma.ninja> Co-authored-by: Remi Lehe <remi.lehe@normalesup.org> Co-authored-by: Axel Huebl <axel.huebl@plasma.ninja> Co-authored-by: Weiqun Zhang <WeiqunZhang@lbl.gov>
