5cdedc29dc Removed AVX dependency from the core library (astaroth_core). Astaroth utils (astaroth_utils) still requires it though because the model CPU solver uses vectorization. 2021-02-17 13:07:16 +02:00

cec9a23dc0 Added a stripped down MPI version of standalone: standalone_mpi. In fact, it's more like a pure simulation module since I've dropped real-time rendering and other old parts that do not work with MPI without heavy modifications. The most important functionalities in addition to simulation have already been adapted to work with MPI (samples/benchmark and samples/mpi) so there's no need to re-create them in standalone_mpi. The current version of standalone_mpi is able to run a basic simulation and I get an agreement with non-mpi and mpi versions after 100 timesteps. There's also draft that's a direct adaptation of what's currently in standalone/simulation.cc (it should be 100% equivalent), but it's currently commented out as I haven't done extensive tests with it. 2020-08-24 19:03:03 +03:00

d966afe830 Added VERBOSE CMake option and made various prints optional to clean the output. VERBOSE is by off by default, pass cmake -DVERBOSE=ON to re-enable various non-critical warning and status prints (important warnings are still visible regardless of the flag). 2020-08-21 21:19:42 +03:00

b847b67805 Disabled building some old samples that are not used or have very specific use cases: genbenchmarkscripts, mpi_reduce_bench, bwtest. Functionality of mpi_reduce_bench should be merged into samples/benchmark when tuning becomes relevant 2020-08-21 19:08:50 +03:00

a753ca92f2 Made cmake handle MPI linking. Potentially a bad idea (usually better to use mpicc and mpicxx wrappers) 2020-05-30 22:02:39 +03:00

b719306266 Upped the required CMake version. This may be an issue on older machines. Instead of making the user to compile CMake themselves in this case, we could maybe add CMake as a submodule. In any case supporting older CMake versions is not really an option because CUDA support with those is so bad and requires adding dirty hacks to the clean cmakefiles we have now. 2020-05-30 19:36:32 +03:00

daa895d2fc Fixed an issue that prevented Ninja being used as an alternative build system to Make. There's no signifant performance benefit to using Ninja though. Build times: 29-32 s (Make) and 27-28 s (Ninja) 2020-02-10 14:37:48 +02:00

6dfe3ed4d6 Added out-of-the-box support for MPI (though not enabled by default). Previously the user had to pass mpicxx explicitly as the cmake compiler in order to compile MPI code, but this was bad practice and it's better to let cmake handle the include and compilation flags. 2020-01-28 15:59:20 +02:00

f8cd571323 Now CMake and compilation flags are functionally equivalent with the current master branch, not taking into account the deprecated flags. Also various small improvements to building. 
Deprecated flags:
        * BUILD_DEBUG. This was redundant since CMake also has such flag. The build type can now be switched by passing -DCMAKE_BUILD_TYPE=<Release|Debug|RelWithDebugInfo|...> to cmake. See CMake documentation on CMAKE_BUILD_TYPE on all av
        * BUILD_UTILS. The utility library is now always built along the core library. We can reintroduce this flag if needed when the library grows larger. Currently MPI functions depend on Utils and without the flag we don't have to worr
        * BUILD_RT_VISUALIZATION. RT visualization has been dormant for a while and I'm not even sure if it works any more. Eventually the RT library should be generalized and moved to Utils at some point. Disabled the build flag for the t

9d70a29ae0 Now the minimum cmake version is 3.9. This is required for proper CUDA & MPI support. Older versions of cmake are very buggy when compiling cuda and it's a pain in the neck to try and work around all the quirks. 2019-12-05 15:35:51 +02:00

72af2cf31d acc is now built with cmake instead of the old build script. This was mainly done to fix compilation on Puhti where I had problems linking flex even though it is available. As an added bonus the code is now safer to build since all dependencies are now rigorously tracked by cmake and make, and f.ex. change in the compiler now forces also the whole library to be rebuilt (which is the behaviour we want) 2019-09-24 16:57:19 +03:00
