Abstract:
A method for determining an optimal set of users which are to be contained in a main memory at a given time, the method comprising:(i) tracing for each active user a usage of computer resources; (ii) evaluating for each inactive user an expected usage of computer resources; (iii) determining a replacement cost to delete and then subsequently re-instate into said main memory for each said active user and for each said inactive user; (iv) identifying a set of users to be resident in main memory at a given time; and (v) employing a user measure based upon the usage of computer resources based upon input from steps (i)-(iv), for determining a dynamic user replacement plan for maintaining an optimal set of users main memory at a given time, thereby allocating computer resources at any given time for the optimal set of users, such that system usage is optimized, whereby a user with a lowest replacement cost is replaced as necessary to maintain an optimal set of users.
