Update MPI wrappers to be more flexible and handle C++/MPI types correctly

4

Currently MPI wrappers implemented in [coreneuron/mpi/mpispike.cpp](https://github.com/BlueBrain/CoreNeuron/blob/5a93d9b2b256a12acbaf83085044aba2cc56746f/coreneuron/mpi/mpispike.cpp#L485) have quite some limitations: * they were derived from old C style code * for different argument types there are different functions i.e. code...

Fix memory leaks reported by valgrind

4

While running valgrind memory checks, I see following possible leaks: ``` mpirun -n 1 /gpfs/bbp.cscs.ch/ssd/apps/hpc/jenkins/deploy/tools/2020-02-01/linux-rhel7-x86_64/gcc-8.3.0/valgrind-3.15.0-wnjdwmga6k/bin/valgrind --leak-check=full bin/x86_64/special-core -e 100 -d ../tests/integration/ring --mpi --ms-phases 2 --ms-subintervals 2 --cell-permute 2 ==185751== Memcheck,...

Make sure patternstim input file has gid as integers

4

See this internal [JIRA ticket](https://bbpteam.epfl.ch/project/issues/browse/CNEUR-350) : User has input file: ``` /scatter 1000.15876308 221273.0 1000.16120151 221145.0 1000.1612057 221043.0 ``` The second column is gid and it should be integer form...

Recently we have updated NEURON-CoreNEURON usage workflow in #374 (see [README](https://github.com/BlueBrain/CoreNeuron#installation)). The [NMC portal](https://bbp.epfl.ch/nmc-portal/microcircuit) provides various cell models. As part of this ticket, we should document instructions to run these...

Currently we have minimal test (ringtest) for direct memory mode. We should enable one of the BBP circuit with direct memory mode transfer.

Currently CoreNEURON build options are very strict when it comes to various backends. We should have one build to allow following: * cpu as well as gpu support * mod2c...

Should we create list of most commonly used mod files with POINTER and Random123?

1

While making models compatible to CoreNEURON, one of the first thing that needs to be fixed is POINTER variables and use of random number streams. I wonder if there are...

Based on BBP's [internal JIRA ticket](https://bbpteam.epfl.ch/project/issues/browse/HPCTM-1370): min delay is calculated as: ``` mindelay_ -= dt; if ((mindelay_ < 1e-9) || (mindelay_ < dt)) { hoc_execerror("usable mindelay is 0", "(or less...

Enable multi-threading tests (MPI+OpenMP) under CI

3

I think we are currently we running pure MPI tests under CI. We should run MPI+OpenMP tests to catch any threading errors.

Few years ago we added reportinglib interface in CoreNEURON due to immediate deadline and feature requirement for BBP simulations. * As these features are BBP library specific, similar to NEURODAMUS,...
