2019-11-04Extract streaming pattern into Mako definitionsAdrian Kummerlaender
This should allow for plugging in e.g. a AA pattern implementation without without touching any file but `AA.$target.mako`. OpenCL and C++ target templates now look basically the same and could potentially be merged. However this would decrease flexibility should more differences appear in the future. Maintaining separate template files is an acceptable overhead to preserve flexibility.
2019-11-02Import `sympy.ccode` inside templates instead of as argumentAdrian Kummerlaender
2019-11-02Restructure LBM model / lattice distinctionAdrian Kummerlaender
2019-10-31Call symbolic generator inside code templatesAdrian Kummerlaender
This paves the way for dropping in other LBM collision models. As a side benefit the default momenta calulcation is now fully inlined where possible.
2019-10-30Move C++ example to boltzgen_examples repositoryAdrian Kummerlaender
2019-10-29Don't try to reuse population layout for moment array indexingv0.1.1Adrian Kummerlaender
2019-10-29Unify AOS, SOA specific cell preshift between targetsAdrian Kummerlaender
SOA and AOS should not be target specific, neighbor offset calculation / bijection between gid and cell coordinates should be customizable.
2019-10-27Optionally generate cell-list-based OpenCL dispatch functionsAdrian Kummerlaender
Requires different function naming as OpenCL 1.2 doesn't support overloads. The OpenCL kernel code generated using this commit was successfully tested on an actual GPU. Time to set up some automatic validation.
2019-10-27Accept cell id as parameter in OpenCL functionsAdrian Kummerlaender
It is more flexible to place OpenCL thread ID dependent dispatching in a separate function.
2019-10-27Add bounce back boundary conditionAdrian Kummerlaender
2019-10-27Use Mako defines to generate momenta boundariesAdrian Kummerlaender
2019-10-27Separate functions into separate template filesAdrian Kummerlaender
Selection of the desired templates is possible via a new `functions` parameter.
2019-10-26Add extra toggle for OpenMP in C++ test functionAdrian Kummerlaender
Yields ~160 MLUPs on a Xeon E3-1241 for D2Q9 double precision lid driven cavity. Obviously not anywhere near what is possible on GPUs but respectable for a CPU implementation. Especially considering how simple it is.
2019-10-26Change C++ test function to LDC with optional VTK outputAdrian Kummerlaender
2019-10-26Generate primitive velocity momenta BC for C++ targetAdrian Kummerlaender
2019-10-26Support passing additional string arguments to the generatorAdrian Kummerlaender

2019-10-24Extract offset helper into target and layout specific classesAdrian Kummerlaender
2019-10-24Add test template for C++, enable switching between AOS and SOAAdrian Kummerlaender
2019-10-23Some cleanup, add `collect_moments` to C++ templateAdrian Kummerlaender
2019-10-22Add basic Generator classAdrian Kummerlaender
2019-10-21Pull in C++ template from symlbm_playground's standalone branchAdrian Kummerlaender
2019-10-21Pull in basics from symlbm_playgroundAdrian Kummerlaender
It's time to extract the generator-part of my GPU LBM playground and turn it into a nice reusable library. The goal is to produce a framework that can be used to generate collision and streaming programs from symbolic descriptions. i.e. it should be possible to select a LB model, the desired boundary conditions as well as a data structure / streaming model and use this information to automatically generate matching OpenCL / CUDA / C++ programs.
