* The estimation is very approximative because the value returned is the time the task would take if it was executed
* now and if it was the only task.
*
- * \param task the task to evaluate
* \param host_count number of hosts on which the task would be executed
* \param host_list the hosts on which the task would be executed
* \param flops_amount computation amount for each host(i.e., an array of host_count doubles)
