8cc9281045 Double versions of some sqrt, cos and sin were used in model_rk3.cc instead of the long double versions, fixed. 2019-07-09 19:03:15 +03:00

e6c770cbee Added a synchronization after acLoadDeviceConstant since it is now stated to be asynchronous 2019-07-09 19:00:08 +03:00

0bda016e17 Reviewed the Astaroth interface. Now there's a clear distinction between synchronous and asynchronous functions. For basic usage, we provide a set of functions that are always safe to call (acIntegrate, acLoad, etc), but because of this, must be quite restricted in the sense that f.ex. the whole mesh must be loaded at once and computations cannot be executed concurrently on multiple GPUs. For more advanced users we provide asynchronous functions (such as acLoadWithOffset). Since we cannot know how the asynchronous functions are called (for example, when the integration step has been fully completed and the halos of neighboring subgrids can be safely communicated between GPUs), the responsibility of synchronization must be left to the user. In the existing implementations we currently use only the basic "safe" set of functions (except in renderer.cc), so the existing functionality has not been changed with these latests commits. Autotests also pass. 2019-07-09 18:42:00 +03:00

f9be905703 Corrected an unit coversion issue from forcing. 
Now noticing these because of switching to gcc 8.

556cb77dbb Removed weird unused functions from model_rk3.cc. I have no idea where these came from. Probably remnants from the time I was pulling all-nighters to finish my thesis. 2019-07-03 18:06:40 +03:00

b4eea4b6b6 Changed #if 0 to #if LFORCING instead to get the code to compile if forcing is used (even though autotesting does not support it yet). Also more autoformatting. Maybe I should disable it or then everyone should start using it to avoid cluttering commits with these superficial changes 2019-07-03 17:49:34 +03:00

609cfaea14 Commenting the unused variables in simulation.cc a few commits back was the wrong move since the variables are needed if LFORCING it set. 2019-07-03 17:46:50 +03:00

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

9b2e9d376f helical_forcing_k_generator() added. 
Now Helical forcing almost works. I just need scale to force per tiome step
correctly. The current formulation is wrong.

cda17c9b08 VERBOSE_PRINTING flag is now globally used in the whole program and should be used to suppress development/debugging-related printing. Also added comments to the new interface function acCheckDeviceAvailability and made it free from side effects. 2019-06-26 18:50:15 +03:00

next step in to generate random waves in the CPU with a chosen degree of helicity etc.

a5ab388af7 Fixed a compilation error when not using entropy. This is a temporary workaround. There is no model solution for hydro only, therefore autotesting will break if entropy is not used. Note: LINDUCTION, LENTROPY and other logical flags are duplicated in both astaroth.h and stencil_process.sps. These flags are not linked and there will be errors and weird behaviour if a flag is set in one file and not in another. 2019-06-19 20:18:25 +03:00

f970dca68c Disabled a power-of-two error check as this may be too strict. See test_dims in autotest.cc which dimensions are guaranteed to work with reductions. Other dimensions may also work but are not yet extensively tested 2019-06-17 18:32:23 +03:00
