79fe634a84 Tested and works. Now it is possible to continue the simulatiom with a specific file number. 
Next task: move I/O to src/utils/

Now to actual testing. Can we read and cotinue from and old file?

54d89f7a46 In principle should read a specifield old run. 
Needs still testing and compilation.

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

9e57aba9b7 New feature: ScalarArray. ScalarArrays are read-only 1D arrays containing max(mx, max(my, mz)) elements. ScalarArray is a new type of uniform and can be used for storing f.ex. forcing profiles. The DSL now also supports complex numbers and some basic arithmetic (exp, multiplication) 2019-09-02 21:26:57 +03:00

6ea02fa28e DSL now 'feature complete' with respect to what I had in mind before the summer. Users can now create multiple kernels and the library functions are generated automatically for them. The generated library functions are of the form acDeviceKernel_<name> and acNodeKernel_<name>. More features are needed though. The next features to be added at some point are 1D and 2D device constant arrays in order to support profiles for f.ex. forcing. 2019-08-27 18:19:20 +03:00

20138263f4 The previous attempt (dsl_feature_completeness_2019-08-23) to enable arbitrary kernel functions was a failure: we get significant performance loss (25-100%) if step_number is not passed as a template parameter to the integration kernel. Apparently the CUDA compiler cannot perform some optimizations if there is a if/else construct in a performance-critical part which cannot be evaluated at compile time. This branch keeps step_number as a template parameter but takes rest of the user parameters as uniforms (dt is no longer passed as a function parameter but as an uniform with the DSL instead). 2019-08-27 17:36:33 +03:00
