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

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

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

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

f1138b04ac Cleaned up the MPI implementation, removed all older implementations (removed also MPI window implementation which might be handy in the future when CUDA-aware support is introduced). If the removed stuff is needed later, here are some keywords to help find this commit: MPI_window, sendrecv, bidirectional, unidirectional transfer, real-time pinning, a0s, b0s. 2020-05-28 16:42:50 +03:00
