666f01a23d Benchmarking program for scalar mpi reductions, and nonbatch script for running benchmarks 
- New program mpi_reduce_bench
      - runs testcases defined in source
      - writes all benchmark results to a csv file, tags the testcase and benchmark run
      - takes optional argument for benchmark tag, default benchmark tag is a timestamp
    - New script mpibench.sh
      - runs the mpi_reduce_bench with defined parameters:
        - number of tasks
        - number of nodes
        - the benchmark tag for mpi_reduce_bench, default tag is the current git HEAD short hash

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

c7c2a3eea4 Simplified/rewrote the root CMakeLists.txt s.t. compilation bugs are easier to pinpoint. WIP, not all functionality is yet enabled (primarily compilation options like MPI_ENABLED and others) 2020-01-23 20:07:59 +02:00

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

24f46324e0 Deprecated the old style of selecting a config file (was a compile-time parameter). The config file is now a runtime parameter and can be changed without recompilation. Usage: ./ac_run -s <path/to/config/file/relative/to/ac_run/path>. config/astaroth.conf is selected by default if the custom path is not supplied to ac_run. 2019-09-18 19:22:15 +03:00

3bb6ca1712 The Astaroth Code Compiler (acc) is now built with cmake. Additionally, make is now used to generate the CUDA headers from DSL sources. The headers are also properly regenerated whenever a DSL file has been changed. With this commit, the DSL is now seamlessly integrated to the library and we no longer need complicated scripts to figure out the correct files. The current workflow for using custom DSL sources is to pass the DSL module directory to cmake, f.ex. cmake -DDSL_MODULE_DIR=/acc/mhd_solver. Note that the path must be absolute or then given relative to the CMakeLists.txt directory. f.ex cd build && cmake -DDSL_MODULE_DIR=../acc/mhd_solver does not work. CMake then takes all DSL files in that directory and handles the rest. 2019-09-18 17:28:29 +03:00

4ce51ea60e Now the generated CUDA header files are completely local (placed in the build directory) instead of depending on some predefined directory structure. This allows users to swap between build directories without having to recompile. 2019-09-12 20:11:21 +03:00

d614a03653 Made CMake to use the default compiler on system PATH. If the generic compiler names (cc, c++) point to some old version, then cmake would otherwise use those instead of the latest available compiler. 2019-07-29 16:07:31 +03:00

24f49ce461 Host code now compiled according to the C++11 standard. The device code has used C++11 for a while now and it's good to use a single standard consistently throughout the project. Old Intel compilers (~14.0) do not seem to support C++11 but the code should still compile since the flag is ignored in that case. 2019-07-04 16:01:02 +03:00

2c4d129216 -Werror-all disabled from Intel compiler flags 
Because produces cryptical messages preventing compilation. The messages do not
tell anything about the problem and are also at odds with some gcc specific
pragma commands. If we can resolve these issues, we can turn it back.
