2019-11-05Implement AA pattern for C++ targetAdrian Kummerlaender
Note that special care has to be taken to provide ghost cells around active cells so the algorithm has somewhere to stream to and from. This is also the case for the AB pattern but there they only have to be equilibrilized once instead of after every other time step. Even when such an equilibrilization is performed there is still a potential bug as inbound populations at the outer boundary are never streamed to (this is not a problem for AB using pull-only streaming). A vectorizable solution may require direction-specific ghost cell equilibrization.
2019-11-04Drop AB suffix from streaming pattern definition namesAdrian Kummerlaender
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.
2019-11-02Improve lattice, model selection error reportingv0.1.2Adrian Kummerlaender
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.

2019-10-29Return cell id as string expression when requiredAdrian Kummerlaender
2019-10-29Add support for generating custom templates in boltzgen's contextAdrian Kummerlaender

2019-10-29Move further generator arguments into its constructorAdrian Kummerlaender
2019-10-29Extract cell indexing functionAdrian 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.
2019-10-28Set default order for custom ndindex overloadv0.1.0Adrian Kummerlaender
2019-10-28Use order-accepting ndindex method for generating cell indicesAdrian Kummerlaender
2019-10-28Add basic setup.pyAdrian Kummerlaender
No guarantee for correctness - I mostly fiddled this together in order to use common nixpkgs python package functions for including boltzgen in other shell environments.
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.

2019-10-27Add READMEAdrian Kummerlaender
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.

2019-10-27Disable bytecode cachingAdrian 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.

2019-10-26Add optional flag to disable CSEAdrian Kummerlaender
2019-10-26Add BGK relaxation time argumentAdrian Kummerlaender
Still thinking how various collision models (BGK, MRT and so on) may be nicely abstracted in this setting.
