Within the parallel genetic algorithm framework, there currently exists a growing dichotomy between coarse-pain and fine-grain parallel architectures. This paper attempts to characterize the need for fine-grain parallelism. and to introduce and compare three models of fine-grain parallel genetic algorithms (GAS). The performance of the three models is examined on seventeen test problems and is ...

a nano/ultra-fine grain al-0.2wt% zr alloy was produced by accumulated roll bonding (arb) processafter 10 cycles. the fraction of high angle grain boundaries increased from 8% to 65.4% during 10passes during arb process. this alloy was subjected to tensile test at different temperatures (523,573and 623 k) and strain rates (0.1 and 0.01 s-1). the optimum condition of temperature and strain rate ...

Sparse matrix problems require a communication paradigm different from those used in conventional distributed-memory multiprocessors. We present in this paper how fine-grain communication can help obtain high performance in the experimental distributed-memory multiprocessor, EM-X, developed at ETL, which can handle fine-grain communication very efficiently. The sparse matrix kernel, Conjugate G...

Computer hardware is at the beginning of the multi-core revolution. While hardware at the commodity level is capable of running concurrent software, most software does not take advantage of this fact because parallel software development is difficult. This project addressed potential remedies to these difficulties by investigating graphical programming and fine-grain parallelism. A prototype sy...

Progress: We have been investigating the use of dynamic cache resizing techniques for energy reduction. The idea of cache resizing is to match the active cache size with the current program cache usage requirements. When the cache usage is small, we can turn off parts of the cache. Neither active switching energy nor static leakage energy is dissipated in the part of the cache that is turned of...

Granulated Sugar A. R. N E E S 1 The users of sugar, especially the commercial users, are making increased demands for sugars of various types based on grain size. Some candy makers want coarse sugar because it handles bet ter in their kettles, bakers want fine sugar because it creams more easily in cake batter, and many housewives want an intermediate size which is neither coarse nor fine. If ...

This paper presents a new version of ALFA VER92], a ne grain dataaow machine. This machine uses the static dataaow execution model and is constituted by 128 clusters; each cluster groups 128 identical Functional Units (FU) with homogeneous I/O conditions. The peculiarity of this machine is the possibility to map directly part of dataaow graph programs in hardware for the simple FU design VER94b...

The advancement of transmission electron microscopy has made it possible to analyze the metallographic structure of steel products on a nanoscopic scale, which leads to the detail understanding of microstructures such as fine precipitates and grain boundaries. The application of the characteristic technology to commercial steel products requires consistency in the structural analysis of steel f...

In order to cope with the increasing leakage power and the increasing device variability in VLSI’s, the required control size of both the space-domain and the time-domain is decreasing. This paper shows the several recent fine-grain voltage engineerings for the low power VLSI circuit design. The space-domain fine-grain voltage engineering includes the fine-grain power supply voltage with 3D-str...

Electron micrographs of directcarbon replicas having magnifications of 5400 to 23, 500 times reveal in detail the grain size, shape, and packing of the particles comprising very fine-grained limestones. At these magnifications, however, only portions of a few grains in mediumor coarsegrained limestones can be observed. Grain contacts are mostly curvilinear in very fine-grained limestones but ar...
