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

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
