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

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

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

b53cabbc44 Made the DSL syntax less confusing: Input and output arrays are now ScalarField and VectorFields instead of scalars and vectors. C++ initializers are now also possible, removing the need to declare Fields as int or int3 which was very confusing, like "what, you assing an int value to a real, what the &^%@?" 2019-08-08 21:07:36 +03:00

7e6361a92a Forcing hotfix. 
Will need more investigation before scientific runs. Now just something to correct the obvious bug.

81a09501b8 Removed deprecated LNT0 and LNRHO0 defines, now the actual configuration parameters are used (AC_lnrho0 and AC_lnT0). Also accidental autoformatting again, there seems to be stray spaces before linebreaks in some files which get automatically removed by my text editor 2019-07-03 17:23:37 +03:00

334ff868d9 Forcing disabled from autotest and from defaults. 
It is not suitable function of the autotest tool. If there in really a
mandatory need to add it. I will need special help from Johannes.

1e6740f999 Added the equations for hydro only for both CPU and GPU. NOTE: NOT RIGOROUSLY CHECKED FOR CORRECTNESS. I just took the equations used with entropy and removed the terms which included entropy and magnetic fields 2019-07-01 18:56:13 +03:00

21e9fc943b Removed all defines from the stencil assembly and processing files and moved them to the new stencil_defines header. There were spaces after some linebreaks which were removed when I autoformatted the code and that's why there seems to be more changes that there actually is. 2019-07-01 18:40:13 +03:00

0600790f41 Corrected a bug in the timestep and some scaling problems. 
Now I can reach a saturated stated in forcing without crashing the code.

But we will need a wavenumber generator to add stochasticity.
