This paper presents an optimal economic dispatch for power plants by using modified particle swarm optimization (PSO) algorithm. The economic dispatch problem in power systems is to determine the optimal combination of power outputs for all generating units in order that the total fuel cost can be minimized, furthermore, all practical constraints can be(More)
In response to the increasing ubiquity of multicore processors, there has been widespread development of multithreaded applications that strive to realize their full potential. Unfortunately, lock contention within operating systems can limit the scalability of multicore systems so severely that an increase in the number of cores can actually lead to(More)
Due to the limitation of power and processor complexity on traditional single core processors, multi-core processors have become the mainstream. One key feature on commodity multi-cores is that the last level cache (LLC) is usually shared. However, the shared cache contention can affect the performance of applications significantly. Several existing(More)

Multi-core architectures have become mainstream. Trends suggest that the number of cores integrated on a single chip will increase continuously. However, lock contention in operating systems can limit the parallel scalability on multi-cores so significantly that the speedup decreases with the increasing number of cores (thrashing). Although the phenomenon(More)
Multi-core processor architectures have become ubiquitous in today's computing platforms, especially in parallel computing installations, with their power and cost advantages. While the technology trend continues towards having hundreds of cores on a chip in the foreseeable future, an urgent question posed to system designers as well as application users is(More)
In an open electricity market, generation companies (GENCO) have to optimally bid to gain more profits with incomplete information of other competing generators. In this structure, market participants must develop their bids in order to maximize their profits. Building optimal bidding strategies for GENCO could need to evaluate some market parameters such(More)
Multi-core architectures have become mainstream. Trends suggest that the number of cores integrated on a single chip will continue to increase. However, lock contention in applications or kernels can degrade the scalability so significantly that the speedup decreases with the increasing number of cores (thrashing). Although the phenomenon can be easily(More)
