b815b62aa7 Enhanced simulation cc. Now magnetic fields diagnostics invoked if needed. 
Also more exit condition so that the simulation will terminate if nan happens or timestep becomes too short.

cec9a23dc0 Added a stripped down MPI version of standalone: standalone_mpi. In fact, it's more like a pure simulation module since I've dropped real-time rendering and other old parts that do not work with MPI without heavy modifications. The most important functionalities in addition to simulation have already been adapted to work with MPI (samples/benchmark and samples/mpi) so there's no need to re-create them in standalone_mpi. The current version of standalone_mpi is able to run a basic simulation and I get an agreement with non-mpi and mpi versions after 100 timesteps. There's also draft that's a direct adaptation of what's currently in standalone/simulation.cc (it should be 100% equivalent), but it's currently commented out as I haven't done extensive tests with it. 2020-08-24 19:03:03 +03:00

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

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

9cd5909f5a BWtest calculates now aggregate bandwidths per process instead of assuming that all neighbor communication can be done in parallel (Within a node one can have parallel P2P connections to all neighbors and we have an insane total bandwidth, but this is not the case with network, we seem to have only one bidirectional socket) 2020-04-09 20:28:04 +03:00

cc9d3f1b9c Found a workaround that gives good inter and intra-node performance. HPC-X MPI implementation does not know how to do p2p comm with pinned arrays (should be 80 GiB/s, measured 10 GiB/s) and internode comm is super slow without pinned arrays (should be 40 GiB/s, measured < 1 GiB/s). Made a proof of concept communicator that pins arrays that are send or received from another node. 2020-04-05 20:15:32 +03:00
