Ns2 project in manchester
Ns2 project in Manchester at each event time, the process may elect to generate or not generate on actual event, where the generated event is an assignment of the value or to ns2 project in Manchester a local variable mapped to a monitoring attributein the process The global event to the evaluated by the monitoring system The global event’s frequency of change for each program run is not known due to the randomness of the individual ns2 project in manchester event generators. In the measurements below, generator processes are first run without monitoring and then the event of interest is analyzed with extended sensors, by the resident monitor, or by the central monitor, respectively, each time measuring the ns2 project in Manchester resulting program perturbation.
The table below depicts the measurement results In all cases above, the actual overhead reported here is dominated by the use of Unix communication ns2 project in Manchester primitives. Thus, the exact amounts of the reported overhead percentages is not relevant. Instead, observe the differences in the amounts reported above. Specifically, ns2 project in Manchester the entry “Unmonitored” depicts the total time in seconds for the unmonitored execution of two generating processes located on the same machine. The entry “Central” assumes ns2 project in Manchester the generation of event records by generator processes each time an actual assignment to attributel or attribute is performed.
Those event ns2 project in Manchester records are then sent to the nonlocal central monitor which compares the values of the respective attributes. Compared to the measurements in row “Central,” it is apparent that a comparison of attribute values using a resident monitor on the generators’ workstation is preferable to central monitoring This result holds despite the additional cost of context ns2 project in Manchester switching caused by the execution of the resident monitor on the generator processes’ workstation.
