* \brief Set the affinities
* \details This function will create the analysis threads and set the affinity
* of this thread and all analysis threads. If MPI_THREAD_MULTIPLE is not
* enabled, the analysis threads will be disabled and the analysis will run in the current thread.
* @param[in] method Method used to control the affinities:
* none - Don't use threads (runs all analysis in the current thread)
* default - Create the specified number of threads, but don't load balance
* independent - Create the necessary number of threads to fill all cpus,
* and set the affinities based on the current process such
* that all threads run on independent cores
* @param[in] N_threads Number of threads, only used by some of the methods
