| | FREENIX Track: USENIX 2002 Annual Technical Conference - Paper |
 | | Ningaui attacks this question the same way Gecko did; it tracks the progress of (or records corresponding to) each call throughout the billing process by tapping the dataflows between systems and within systems. |
 | | Ningaui is inherently scalable because of its loosely coupled design, especially as it's unit of design, the node, is fairly well balanced in terms of CPU and I/O. Figure 6 shows how the performance scales with the number of nodes. |
 | | The foremost goal on Ningaui was to verify this relationship and to evaluate whether or not a loosely coupled cluster of Linux systems was in fact competitive with large, industrial strength, high end SMP servers. |
