Abstract: A method, computer system, and a computer program product is provided for dynamic allocation of resources. A database access pattern is determined by analyzing and monitoring traffic pattern between a pool of resources and a plurality of clients. The relationship between each of the resources is also determined. Access is enabled to a plurality of resources based on the database access and resource relationships, so that the plurality of resources can be accessed but not allocated until processing a request. A consumption model is generated that predicts resource need during a processing request based on the resource relationships, traffic pattern and resources availability. Upon receipt of a subsequent request for processing, consumption model is used to predict resource needs and to dynamically allocate, re-allocate and release the plurality of resources in a cascading manner until completion of subsequent processing request.

Abstract: A region descriptor management method and an electronic apparatus are provided. The region descriptor management method is adapted to a device controller of the electronic apparatus and includes following steps. Region descriptor entries are fetched from a region descriptor table. Each of the region descriptor entries includes a block initial address and a block length to describe a memory block of a memory module. According to the block initial addresses and the block lengths of the region descriptor entries, a portion of the region descriptor entries are adjusted to be at least one current region descriptor entry. Based on the at least one current region descriptor entry, a current region descriptor table is generated.
