This paper describes automatic coarse grain parallel processing on a shared memory multiprocessor system using a newly developed OpenMP backend of OSCAR multigrain parallelizing compiler for from single chip multiprocessor to a high performance multiprocessor and a heterogeneous supercomputer cluster. OSCAR multigrain parallelizing compiler exploits coarse grain task parallelism and near ne gra...

Bed surface particle size patchiness may play a central role in bedload and morphologic response to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of bedload transport, surface grain size, and channel profile with two previously published flume studies that documented bed surface response, and specifically patch development, to reduced sediment sup...

Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...

Dataaow computing is a simple yet powerful mechanism for constructing distributed visualization applications. Most of the current dataaow based visualization systems use coarse-grain computing models. A major problem of the coarse-grain visualization systems is that they introduce multiple copies of large data sets during execution. In this paper we propose a ne-grain method called the Syntax-d...

The shape memory effect and superelastic properties of NiTi (or Nitinol, a nickel-titanium alloy) have already attracted much attention for various biomedical applications (such as vascular stents, orthodontic wires, orthopedic implants, etc). However, for vascular stents, conventional approaches have required coating NiTi with anti-thrombogenic or antiinflammatory drug-eluting polymers which a...

As real-time and embedded systems become increasingly large and complex, the traditional strictly static approach to memory management begins to prove untenable. The high development costs and space requirements of the static approach need to be reduced at a minimal performance penalty and without compromising the predictability of the system. Therefore, the challenge is to provide a dynamic me...

Abstract: A coarse-grained parallel (distributed) computing application using the ISIS toolkit is described. The method should be applicable to any serial program suitable for coarse-grain parallelization. Criteria for parallelizing existing programs, factors which affect the speed of parallel programs, and benefits in addition to quicker turnaround time are described. Future tasks to obtain mo...

Kinetics of dendritic solidification and fragmentation of dendritic crystals in undercooled Ni–Zr samples are studied. Using the capacitance roximity sensor technique and a high-speed-camera system, the dendrite growth velocity has been measured as a function of initial undercooling n solidifying droplets processed by the electromagnetic levitation technique. Analyses of solidified droplets giv...

Evolvable Hardware arises as a promising solution for automatic digital synthesis of digital and analog circuits. During the last decade, a special interest has been focused on evolving digital systems by directly mapping a chromosome on the FPGA configuration bitstream. This approach allowed a great degree of flexibility for evolving circuits. Nowadays, FPGAs routing scheme does not allow doin...
