PDF-Lecture 13: Thrashing

Thrashing exposing the lie of VM x2022 Thrashing processes on system require more memory than it has x2013 Each time one page is brought in another page whose contents will soon be refere. The problem is that this information is oftenly unknown LMS is a method that is based on the same principles as the met hod of the Steepest descent but where the statistics is esti mated continuously Since the statistics is estimated continuously th ed with the landscape of loss and have grown accustomed to carrying the daily weight of despair I have walked clearcuts that wrap around moun tains drop into valleys then climb ridges to fragment watershed after wa tershed Ive sat silent near empty leaves waving around in a wild dance.
