0ccd4e3dbc Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant. 2020-01-28 18:17:31 +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

cc3c2eb926 Added WIP stuff for the Astaroth DSL compiler rewrite. Once this branch is finished only a single source file will be needed (file ending .ac). This revision is needed to decouple absolutely all implementation-specific stuff (f.ex. AC_dsx) from the core library and make life easier for everyone. The plan is to provide a standard library header written in the DSL containing the derivative operations instead of hardcoding them in the CUDA implementation. 2019-10-02 21:03:59 +03:00

a0037d1a44 Modified the syntax of writing real-valued literals with the DSL. Casts are not needed any more: f.ex. 1.0 is implicitly cast to AcReal. The syntax is now more consistent: reals must be explicitly written as a.b, where a and b are some integers. IMPORTANT: Previously the shorthands a. and .b were allowed, not anymore. Using those shorthands will result in a compilation error 2019-10-01 21:14:33 +03:00

b4a6ddb074 Preprocessing writes the intermediate output to *.preprocessed files. This makes debugging various DSL syntax errors much easier since the line number in the error corresponds to the line numbers in these files. 2019-10-01 21:08:38 +03:00

62fa95ca0d The issue on Puhti was that it was missing a static flex library which would have provided the function yywrap. Fixed by removing the static library dependency and adding option noyywrap to the lexer generator file 2019-09-24 17:19:19 +03:00

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

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
