ABSTRACT
Network backbones are often presumed to be
overprovisioned. Yet, the emergence of new applications with unprecedented
bandwidth requirements are likely to quickly change the current state of
affairs. Future Grid applications will require transfer of extremely large
files between different national laboratory and research centers. This research
proposed and developed an adaptive lambda grid scheduling algorithm (ALGSA);
the Varying Bandwidth List Scheduler (VBLS) and the Virtual Finish time (ViFi)
grid scheduler. The effectiveness of the algorithms reduced from 100% to about
83%, 65% and 61% for the proposed adaptive algorithm, the VBLS and the ViFi
algorithms respectively. It can be observed that the proposed adaptive
scheduler performs better than the VBLS and the ViFi algorithms. The VBLS
algorithm performs better than the ViFi algorithm. Furthermore, it can be noticed that the
different in performance gets even more distinct as the number of files
increases.
