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

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

0c63d55fd7 Worked around a compiler bug in CUDA 9.1, which caused an "Internal Compiler Error (codegen): "there was an error in verifying the lgenfe output!". Apparently the compiler got confused by overloaded is_valid() if the input parameter was not passed as a reference in both cases. 2019-06-29 10:49:15 +03:00

f04ef8e64c Forcing function issue not yet fully resolved. 
Now brain hurs. No more today. Break needed.

94a25383a9 Trying to calculate the forcing scaling. 
Causes nans very quickly. Will need to look closer tomorrow again.

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.

Without randomization. Will add next.

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

76d251cd3e Makes now special helical forcing vector. 2019-06-26 18:50:42 +08:00
jpekkila
6bfc5f04f7 Added tighter bounds for gcc and nvcc versions. There was a bit of an chicken-and-egg issue: we need gcc 6.0 in order to get bug 48891 (see gcc bugzilla) fixed, but cuda < 9 supports gcc only up to 5.3. This is not a perfect solution, f.ex. ubuntu 16.04 ships with gcc 5.4 but with the fix backported from later versions so in practice that would also work but is not accepted anymore. 2019-06-26 13:33:03 +03:00

be0e46c814 Can move forcing vector information now from the host to device. 
next step in to generate random waves in the CPU with a chosen degree of helicity etc.

912dffca4f Renamed old single-GPU-only headers in core/kernels to avoid confusion. Only kernels.cuh is used for reductions, integration and boundary conditions at the moment. 2019-06-25 13:58:59 +03:00

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

40b4a61a4c Added DEPRECATED marking to the old forcing function. 
I do not want to remove it yet. Not until something like that exists in the DSL code.
