jpekkila	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

Miikka Vaisala	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.	2019-07-02 18:46:04 +08:00

jpekkila	59086b3e79	Added multi-GPU reductions. Tested to work with 1-2 GPUs with power of two grid dimensions. Requires more testing in special cases (when using exotic grid dimensions and a large number of GPUs)	2019-06-17 14:45:41 +03:00
