Description
Ideally, the maximum number of thread used by ctobssim should be a hidden user parameter, so that a user can start ctobssim from the command line with something like
$ ctobssim threads=10
and the simulation will then run on 10 cores in parallel.
This requires that the maximum number of threads can be controlled from within the code.
By default we should set this parameter to 0, and in this case the automatic method of openmp should be used to determine how many cores are available.
Recurrence
No recurrence.

OpenMP use environment variables, we can easily choose the number of thread by setting the OMP_NUM_THREADS variable.
export OMP_NUM_THREADS=10 ctobssim
By default, the number of threads is the number of cores.
