+ * \param host_nb the number of hosts implied in the parallel task.
+ * \param host_list an array of #host_nb m_host_t.
+ * \param computation_amount an array of #host_nb

+ * \param communication_amount an array of #host_nb*#host_nb doubles.

+ object. It is for user-level information and can be NULL. It can
