We present and evaluate a simple, yet efficient dynamic optimization technique that increases memory-hierarchy performance for pointer-centric applications by up to 24% and reduces cache misses by up to 35%. Based on temporal profiling information, our algorithm reorders individual data members in dynamically allocated objects to increase spatial locality. Our optimization is applicable to all ...

Based on temporal profiling information, our algorithm reorders individual data members in dynamically allocated objects to increase spatial and temporal locality. Our optimization is appli...

ion In order to provide coverage of a number of different target window systems it is necessary to develop an abstract UI model which encompasses the essence of those systems. CAP1 provides an abstract set of basic UI elements for interface construction. Each one of these abstract widgets is mapped onto the target window system via a library or a (CAPI) server which provides the “realization” o...

This article describes the uncertain future of the online catalog, and the tension that exists between creating a cataloging code that meets user needs while adhering to principles deemed important by the cataloging community. Underscoring this tension are the provocative questions posited by the Taiga Steering Committee, which call into question the future of libraries. For the traditional cat...

Recently, a number of usage data representations have emerged that enable the representation of user activities across system and application boundaries. Based on these user activity data, systems can adapt to the users and provide personalized information. A lot of usage data representation formats are already successfully used in real world applications. However, dependent on the purpose, the...

Purpose Access to learning resources in higher education is a prerequisite for effective learning. The purpose of this study investigate how marketing library can influences usage students from the University Education Winneba and Cape Coast Ghana. Design/methodology/approach was grounded pragmatic paradigm guided by mixed methods research approach. sequential explanatory design used that, quan...

Higher Education libraries have traditionally sought to be able to demonstrate the impact their services have on student attainment. This is particularly important in the current economic climate where libraries frequently have to defend their budgets in the face of financial constraints, whilst needing to demonstrate better value for money to students who are now paying more for higher educati...
