Article

Summary

In this paper we have studied the worst case performance of the weighted buddy system of memory management. Specifically we have derived lower bounds of two system parameters NETREQ and NETALLOC for a weighted buddy system in case of unrestricted request sequence and stated a few preliminary results for those parameters in case of allocation only request sequence. We have also given bounds for the same system parameters for exact-fit memory management algorithms to compare the results with those for buddy systems.
