Forgot a pragma insert for the summed_variable templates, and also add some more pragma statement in the main.cpp files, when
objects are created from the device.py file. Now I'll start to do some benchmarks to check when optimizations are useful
Some polishing, bug fixes, and optimizations in the openmp implementation. Benchmarks are on their way, but
the results seems to vary a lot depending on computer architectures, networks, ... Quite some overhead due to
openmp threads creation could maybe be reduce by merging threshold and stateupdate loops, need to check
Now the threshold.cpp file is also handle in parallel, with OpenMP, and thanks to the ordered flag.
This seems to lead to large speed improvement, because the threshold operation is one of the
major bottleneck in according to some profiling.
