VMware Abstract. A major obstacle to virtualizing HPC workloads is a concern about the performance loss due to virtualization. We will demonstrate that new features significantly enhance the performance and scalabil-ity of virtualized HPC workloads on VMware's virtualization platform. Specifically, we will discuss VMware's ESXi Server performance for(More)
This paper presents high-performance collective communication algorithms and implementations that exploit the unique architectural features of the Cell heterogeneous multicore processor. This paper specifically describes novel algorithms <i>for the barrier, broadcast, reduce, all-reduce</i>, and <i>all-gather</i> collective operations, and shows the(More)
Road traffic information has become indispensable for routine vehicular communication but user location privacy an important issue which did not well addressed. An adversary may attack a user by tracking location in routine vehicular communication. Although, continuously changing pseudonyms is a promising solution to attain location privacy in road(More)
This paper presents and validates performance models for a varietyvof high-performance collective communication algorithms for systems with Cell processors. The systems modeled include a single Cell processor, two Cell chips on a Cell Blade, and a cluster of Cell Blades. The models extend PLogP, the well-known point-topoint performance model, by accounting(More)
In the presence of dynamic classloading, performing interprocedural analysis (IPA) too early can lead to repeatedly performing the IPA as new classes are loaded, while performing it too late will cause a performance degradation by running unoptimized code for too long. This paper investigates how programs load classes and how this affects the performance(More)
The Culex quinquefaciatus Say, commonly known as the southern house mosquito, is well known for biting nuisance and vectoring of some fatal diseases. Synthetic chemicals have been relied upon as the major control measure to control mosquitoes. Therefore, we have evaluated 21 insecticides belonging to different chemical classes for their toxicity to C.(More)
Culex quinquefasciatus Say is an important disease vector throughout much of the world. Experiments were conducted to determine the effects of different larval habitat substrates on the fitness and biting efficiency of Cx. quinquefasciatus adults. Our findings indicate that the development time (egg to adult) of larvae reared in irrigation water was 8.63 d(More)
