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

46cfa9cd37 Now using MPI C bindings instead of the (deprecated?) C++ bindings due to compilation issues on some machines (error: cast between incompatible function types, ompi_mpi_cxx_op_intercept) 2020-08-19 15:50:16 +03:00

a85b8b8cd1 MPI: corners are now transferred by default because 1) with those Astaroth works with any symmetric stencil and 2) corners have very small impact on performance. Also disabled resetting the device s.t. one could potentially assign many subgrids to one GPU (f.ex. in AMR) 2020-08-19 12:05:20 +03:00

7e71e32359 Fortran does not seem to really support arrays of pointers, better to modify the interface function to take the f array as an input and use it in C to costruct a proper AcMesh 2020-06-25 20:21:16 +03:00

53b48bb8ce MPI_Allreduce -> MPI_Reduce for MPI reductions + benchmark batch script 
Slightly ugly because this changes the benchmark behaviour slightly
However we now have a way to run batch benchmarks from one script, no need to generate new ones

f7d8de75d2 Reduction test pipeline added to mpitest, Error struct changed: new label field 
- CHANGED: Error struct has a new label field for labeling an error
   - The label is what is printed to screen
   - vtxbuf name lookup moved out of printErrorToScreen/print_error_to_screen
 - NEW: acScalReductionTestCase and acVecReductionTestCase
   - Define new test cases by adding them to a list in samples/mpitest/main.cc:main
 - Minor style change in verification.c to make all Verification functions similar
   and fit one screen

899d679518 Draft of MPI-based reductions acGridReduceScal, acGridReduceVec 
- Calls acDeviceReduceScal/Vec first
 - Both functions then perform the same MPI-reduction (MPI_Allreduce)
 - Not tested

0d80834619 Disabled forcing and upwinding for performance tests. Set default grid size to 512^3. Set default cmake params s.t. benchmarks can be reproduced out-of-the-box. 2020-06-02 14:09:00 +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

f97ed9e513 For reason X git decided to remove integration from the most critical part of the program when merging. Luckily we have autotests. 2020-05-30 20:59:39 +03:00
