Figure 2: Fairness anomaly detected in some BOINC clients. Many clients with a small area (i.e., a small power or a low availability) favor application Continuous-0 .
Figure 3: Fairness visualization after the correction on the implementation of the scheduling algorithm
Figure 4: Observing the slow-start behavior of volunteer clients giving resources to the burst tasks (shown as dark gray) when the burst server becomes active
Figure 5: Observation of an anomaly consisting in the cyclic execution of continuous (light gray) and burst (dark gray) tasks on volunteer clients, about 11 hours after the beginning of the burst period
