....are the subject of future work. 10 tions of application computation time and communication are based on a weighted average of the recent past over a time window. More recent values appear to be a strong predictor [7] 16] 17] and an exponential decay function is used to model this relationship [15]. The SFO determines the application computation values, comp, by simply timing the interval between successive requests from the application. Similarly, the communication times, comm, are computed by timing requests to the remote file server. They are both scaled to give the time based on a ....
....that communication and computation performance is constant. However, in the event that communication and or computation performance exhibits variability, the SFO can adapt to further improve performance. For the Complib runs, we observed that Internet communication performance was not constant [15]. We ran the SourceSFO with a time window of n=5 and n=10 to see if this variance could be exploited. The results indicate that performance could be further improved for appropriate prob Source library AACT . Target library TACCG . Figure 10: Complib with SFO. The application, ....

....This one size fits all approach is not appropriate for all network applications. In addition, the network bottleneck must be addressed in an application specific manner. A Smart File Object (SFO) is application level middleware that buffers file access over a wide area or wireless network [8]. It adaptively prefetches and caches needed data concurrently with application execution to mitigate the impact of the network (Figure 1) The SFO is programmed to be application and network aware to obtain the best possible performance. An SFO is adaptive based on the application s patterns and ....
