b73c2675e8 Added the optimized implementation of acNodeIntegrate where boundconds are done before integration instead of after 2019-08-05 20:10:13 +03:00

b21d2040da Added a test for building an MPI project. Building for the MPI and C API tests is now also disabled by default. 2019-08-05 18:26:12 +03:00

fa6e1116cb The interface revision now actually works. The issue was incorrect order of src and dst indices when storing the mesh. 2019-08-05 17:26:05 +03:00

5232d987c1 Added acStoreWithOffset to the revised interface 2019-08-05 16:18:22 +03:00

6dfd03664d Still does not work. I'm starting to think that instead of this one huge revision, we should modify the existing interface step-by-step. 2019-08-02 15:31:24 +03:00

567ad61465 Multinode MPI implementation should be done later in its own branch. The focus of this branch is to revise the node and device layers. Commented out references to the Grid layer. 2019-08-02 13:54:54 +03:00

69deef66fe Added sum reduction. NOTE: Scalar sum does not pass the automated test but vector sum does. I couldn't see anything wrong with the code itself and I strongly suspect that the failures are caused by loss of precision due to summing a huge amount of numbers of different magnitudes. However I'm not yet completely sure. Something like the Kahan summation algorithm might be useful if the errors are really caused by fp arithmetic. 2019-07-30 14:28:18 +03:00

fdc1e7333c Added macros for getting int3 and AcReal3 device constants from within kernels (and DSL). 2019-07-30 09:10:06 +00:00

a3359b0d04 CONFIG_PATH is now supplied by ac_mkbuilddir. While using would be a bit more idiomatic, ASTAROTH_CONF_PATH is probably safer since ac_mkbuilddir.sh does the copying and knows for sure what the correct path is. 2019-07-29 15:55:27 +03:00

c9fafe41e5 Tidied the CMakeLists, moved stuff to more logical places and added comments. Also tested that ALTER_CONF=ON still works 2019-07-26 15:12:55 +03:00

5044228967 The text editor I use to edit stuff remotely is a complete piece of &^$%$, does not synchronize the files correctly. This commit fixes the issues introduced in the last commit 2019-07-26 14:22:22 +03:00

26316a4d15 The standalone library is now compiled in parallel with the core library. Slightly faster. 2019-07-23 21:26:58 +03:00

be44354b33 Astaroth does not require any additional libraries to be included, which is good. Previously required CUDA and C/C++ math libraries. 2019-07-23 21:03:42 +03:00

f0d1fba55c The pure C test works again. 2019-07-23 21:00:00 +03:00

f322bc8b37 Rewrote all CMakeLists. Now much cleaner and there's a clear separation during compilation between the core and standalone modules. 2019-07-23 20:50:37 +03:00

b65454d523 Stashed some testing files used to make sure that the library can also be used from pure C projects (better compatibility). These changes will never go to master as-is. 2019-07-23 18:24:47 +03:00

0db61dd411 Disabled the project-wide maxrregcount flag by default since it is only beneficial for resource-heavy kernels. The maximum register count should be defined per kernel instead if needed. 2019-07-22 12:58:28 +03:00

074fb26df9 Added TODO_SINK comments. 
The comments were written to map out what essential part are needed for
resolving a system with graviating sink particles. No changes to the code
itself.
