*
* The amount of flops per second available for computing depends on several things:
* - The current pstate determines the maximal peak computing speed (use @ref get_pstate_speed() to retrieve the
* computing speed you would get at another pstate)
- * - If you declared an external load
, then this reduces the available computing speed
- *
(see @ref simgrid::surf::Cpu::set_speed_trace())
+ * - If you declared an external load
(with @ref simgrid::surf::Cpu::set_speed_profile()), you must multiply the
+ *
result of get_speed() by get_available_speed() to retrieve what a new computation would get.
*
* The remaining speed is then shared between the executions located on this host.
* You can retrieve the amount of tasks currently running on this host with @ref get_load().
