Reducing the energy footprint of warehouse-scale computer (WSC) systems is key to their affordability, yet difficult to achieve in practice. The lack of energy proportionality of typical WSC hardware and the fact that important workloads (such as search) require all servers to remain up regardless of traffic intensity renders existing power management(More)
LAPI is a low-level, high-performance communication interface available on the IBM RS/6000 SP system. It provides an active-message-like interface along with remote memory copy and synchronization functionality. It is designed primarily for use by experienced programmers in developing parallel subsystems, libraries and tools, but we also expect power(More)
User-facing, latency-sensitive services, such as websearch, underutilize their computing resources during daily periods of low traffic. Reusing those resources for other tasks is rarely done in production services since the contention for shared resources can cause latency spikes that violate the service-level objectives of latency-sensitive tasks. The(More)
The IBM RS/6000 SP system is one of the most cost-effective commercially available high performance machines. IBM RS/6000 SP systems support the Message Passing Interface standard (MPI) and LAPI. LAPI is a low level, reliable and efficient one sided communication API library, implemented on IBM RS/6000 SP systems. This paper explains how the high(More)

AIM To determine the most commonly used words in the clinical histories of animals naturally infected with Theileria orientalis Ikeda type; whether these words differed between cases categorised by age, farm type or haematocrit (HCT), and if there was any clustering of the common words in relation to these categories. METHODS Clinical histories were(More)
In recent years, wireless body area sensor network is one of the important aspects for the development of the healthcare applications. But, it has several issues based on the security and authentication during the transmission of the data. Because of the influence of the hackers, more importance is been given to security aspect in Wireless Body Area Sensor(More)
