1dfaa08afb The stencils for the staple and rect-staple padded cell implementations are now created and stored by workspace classes that allow for reuse providing the grids remain consistent
The workspaces are now used by the plaq+rectangle gauge action resulting in a further 2x performance improvement as measured on a 16^4 local volume for 2 nodes (16 ranks) of Crusher
2023-06-28 15:11:24 -04:00
f44dce390f Implemented acclerator-optimized versions of localCopyRegion and insertSliceLocal to speed up padding
Fixed const correctness on PaddedCell methods
Fixed compile issues on Crusher
Added timing breakdowns for PaddedCell::Expand and the padded implementations of the staples, visible under --log Performance
Optimized kernel for StaplePadded
Test_iwasaki_action_newstaple now repeats the calculation 10 times and reports average timings
2023-06-27 14:58:10 -04:00
bb71e9a96a Added PaddedCell and GeneralisedLocalStencil header includes to standard base headers
Moved versions of the padded-cell implementations of staple and rect-staple from test code to WilsonLoops header
Added StapleAndRectStapleAll which is now called by the plaq+rectangle action class. Under the hood it uses the padded cell implementations with maximal reuse of the padded gauge links
2023-06-27 11:23:30 -04:00
6f6844ccf1 Added new StapleAll and RectStapleAll functions that return the staples for all mu as an array
Modified plaq+rectangle gauge actions to use the above
Added a test code to confirm the above changes
2023-06-26 15:48:47 -04:00
4c6613d72c Modified RectStapleDouble and RectStapleOptimised to use Gauge-BC respecting CshiftLink
Added test code tests/debug/Test_optimized_staple_gaugebc demonstrating equivalence of above to RectStapleUnoptimised for cconj gauge BCs
Removed optimized staple only being used for periodic gauge BCs; it is now always used
2023-06-26 10:20:23 -04:00
36cc9c524f Threaded the constructor of GeneralLocalStencil 2023-06-23 09:57:38 -04:00
4241c7d4a3 Imported coalescedReadGeneralPermute GPU implementation from Christoph
Fixed bug in padded staple code where extract was being called on the result before the GPU view was closed
Fixed compile issue with pointer cast in padded staple code
Added timing summaries of padded staple code and timing breakdown of staple implementation to Test_padded_cell_staple
2023-06-21 16:01:01 -04:00
7b11075102 The user can now specify the implementation of Cshift used by the PaddedCell class through a virtual base class API. Implementations for default (regular Cshift) and for gauge links (which respects the gauge BCs)
Fixed const-correctness for PaddedCell and ConjugateGimpl::setDirections
Modified test code for padded-cell implementation of staple, rect-staple to use cconj BCs
2023-06-20 17:09:56 -04:00
abc658dca5 Added coalescedReadGeneralPermute CPU implementation based on Christoph's GPT code
In a test code, implemented a padded-cell version of the staple and rectangular-staple calculation
