In this paper, we give an overview of our automatic computation and data decomposition scheme in the EPPP compiler 1 for distributed memory machines. Such automatic techniques can be also be used in compilers for programminglanguages such as HPF (High-Performance Fortran) in conjunction with the user-speciied data distribution directives. A pilot EPPP compiler has been implemented and prelimina...

The Descartes Modeling Language (DML) is a novel architecture-level language for modeling performance and resource management related aspects of modern dynamic software systems and IT infrastructures. Technically, DML is comprised of several sub-languages, each of them specified using OMG’s Meta-Object Facility (MOF) and referred to as meta-model in OMG’s terminology. The various sublanguages c...

the effects of aflatoxin (af) (0.0 and 0.5m g kg-1) and high grade sodium bentonite (hgsb) (5, 7.5 and 10 g kg-1) were tested in an in vivo study including 8 dietary treatments with three replicates of 14 birds per diet per replicate, using a total of 336 broiler chicks up to five weeks. results showed that chicks receiving af contaminated feed had significantly (p≤ 0.05) suppressed body weight...

the efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. conclusions were drawn regarding selection of solid phase according to pore size, rigidity, ph stability, chemistry of derivation and activation, and gross concentration of immobilized ligand required fo...

background: a simple and sensitive high performance liquid chromatography-electrospray ionization mass spectrometry method has been evaluated for the assignment of clonidine hydrochloride in human plasma. methods: the mobile phase composed of acetonitrile-water 60:40 (v/v) and 0.2% formic acid 20 µl of sample was chromatographically analyzed using a repacked zorbax-xdb-ods c18 column (2.1 mmx30...

While the emerging field of privacy preserving data mining (PPDM) will enable many new data mining applications, it suffers from several practical difficulties. PPDM algorithms are challenging to develop and computationally intensive to execute. Developers need convenient abstractions to simplify engineering of PPDM applications. The individual parties involved in the data mining process need a...

High speed signal processing is often performed as a pipeline of functions on streams or blocks of data. In order to obtain both flexibility and performance, parallel, reconfigurable array structures are suitable for such processing. The array topology can be used both on the micro and macro-levels, i.e. both when mapping a function on a fine-grained array structure and when mapping a set of fu...

This paper contributes a distributed packet controller which reduces queueing to a single stage in two-stage packet switches. Software and neural network based controllers are described. Simulations under a range of traffic conditions for a 1024x1024 switch size shows the simplest architecture has the best performance.

Switch-based interconnects are used in a number of application domains including parallel system interconnects, local area networks, and wide area networks. However, very few switches have been designed that are suitable for more than one of these application domains. Such a switch must offer both extremely low latency and very high throughput for a variety of different message sizes. While som...
