Load generation is a suitable concept for system level test of complex systems. We present a novel approach especially for service based systems. Test scenarios are defined as inputs and describe a quantification of the wanted load to a service. A test-automation component partitions and distributes these abstract load values to a set of clients. These clients execute service requests to genera...

Computational Fluid Dynamics (CFD) applications are “highly parallelizable” and can be distributed across a cluster of computers. However, because computation time can vary with the distributed part (mesh), the system loads are unpredictable and processors can have widely different computation speeds. Load balancing (and thus computational efficiency) across a heterogeneous cluster of processor...

in methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...

BACKGROUND Some of the mechanisms underlying cell division and partitioning of the cellular components into the daughter cells are well known. Within the endomembrane system, there is a general cessation of membrane traffic, including endocytosis and endosome fusion, at the onset of mitosis. However, the fate of endosomes and lysosomes during mitosis has been less well studied. RESULTS Using ...

In this paper we study speaker linking (a.k.a. partitioning) given constraints of the distribution of speaker identities over speech recordings. Specifically, we show that the intractable partitioning problem becomes tractable when the constraints pre-partition the data in smaller cliques with non-overlapping speakers. The surprisingly common case where speakers in telephone conversations are k...

We consider the problem of adaptive cell sectorization i n a CDMA system. Specifically, given the user distribution in a cell, we investigate the two problems of how to appropriately sectorize the cell such that we minimize the total received power and the total transmit power spent by all the users, in both cases, while giving each user acceptable quality of service. The optimum arrangement eq...

Distribution of the tasks amongst the various computing nodes is itself an intellectually challenging problem in the high performance distributed computing systems. To choose the appropriate strategy for the required system is difficult without the meaningful comparison of the existing task partitioning and load balancing strategies. The effectiveness of the strategy depend on the number of fac...
