ac92123842 Made a note about a bug in 083ff59 , just to remember that code is now more correct. 2019-09-02 18:40:38 +08:00

f3a36ec276 Moved definition location of AC_nx_min etc. Otherwide DSL does not compile the code correctly!!! 2019-09-02 18:29:16 +08:00

b4cd92da0c Now compiles and runs. 
PLEASE NOTE THAT FLAGS NEED TO BE SET SEPARATELY IN simulation.cc and renderer.cc FOR LSINK and LFORCING!

02ac6c956f Desperately trying to port the new changes of DSL. 
Still work to do.

6ea02fa28e DSL now 'feature complete' with respect to what I had in mind before the summer. Users can now create multiple kernels and the library functions are generated automatically for them. The generated library functions are of the form acDeviceKernel_<name> and acNodeKernel_<name>. More features are needed though. The next features to be added at some point are 1D and 2D device constant arrays in order to support profiles for f.ex. forcing. 2019-08-27 18:19:20 +03:00

230230ead9 Added a script for preprocessing the device files. Useful for inspecting whether the DSL code is generated correctly. 2019-08-27 18:15:30 +03:00

20138263f4 The previous attempt (dsl_feature_completeness_2019-08-23) to enable arbitrary kernel functions was a failure: we get significant performance loss (25-100%) if step_number is not passed as a template parameter to the integration kernel. Apparently the CUDA compiler cannot perform some optimizations if there is a if/else construct in a performance-critical part which cannot be evaluated at compile time. This branch keeps step_number as a template parameter but takes rest of the user parameters as uniforms (dt is no longer passed as a function parameter but as an uniform with the DSL instead). 2019-08-27 17:36:33 +03:00

5b686bc659 Fixed on/off switch for forcing and accretion, now forcing only happens for first 1000 steps (currently hard-coded), and accretion only happen after 1000 steps. 2019-08-20 23:12:42 +08:00

eda83e5807 Added on/off switch for forcing and accretion. Now both set to take effect in 1000 steps. 2019-08-20 12:08:06 +08:00

5b7408eb55 User config param overhaul complete, works. If I haven't missed anything, all fields and user parameters, and everything related to simulation can now be declared with the DSL. The only thing that you need to do is to fill the declared symbols with data, like with OpenGL and GLSL. 2019-08-19 18:43:16 +03:00

51cf1f1068 The C header is now generated from the DSL, stashing the changes just to be sure since I might overwrite something when updating the compilation scripts to work with this new scheme 2019-08-19 18:19:28 +03:00

d801ebdd41 Now parameters and vertexbuffers (fields) can be declared with the DSL only. TODO: translation from the DSL header to C 2019-08-19 17:35:03 +03:00

bcdd827a4f Added a proper declarations for all user-specified uniform. Note: built-in uniforms are not correctly translated into CUDA 2019-08-19 17:05:56 +03:00

0208d55e4e Moved STENCIL_ORDER and NGHOST out of user-defined parameter as these are actually internal defines used to configure the built-in functions. Additionally, renamed all explicitly declared uniforms from dsx -> AC_dsx in the DSL in preparation for having clear connection between DSL uniforms and the library parameter handles created by the user (AcRealParam etc) 2019-08-19 16:40:47 +03:00

e89897985e Battled with math.h and cmath. We probably should move from C standard libraries to C++ ones internally (in places which are not visible via the interface) 2019-08-19 14:02:30 +03:00
