Grain types

Water-Vapor Permeability. Water-vapor permeabiUty depends on the polymer used for the coating layer and its stmcture. Vinyl-coated fabrics have Httie water-vapor permeabiUty due to the coating layer. Although polyurethane polymer is water-vapor permeable, urethane-coated fabrics also have low permeabiUty values due to their soHd layer stmcture. On the other hand, man-made leathers have good permeabiUty values as high as that of leather due to their porous layer stmcture. The permeabiUty of grain-type is lower than that of suede-type, influenced by finishing method.

Backscattered electron image of a portion of a fine-grained Type A CAI in the Efremovka CV3 chondrite. This inclusion consists of nodules of spinel (sp) surrounded by anorthite (an) and thin rims of pyroxene (px). This CAI may be an aggregate of condensates.

Figure 3 Nitrogen and carbon isotopic ratios of individual presolar SiC grains. Because rare grain types were located by automatic ion imaging, the number of grains of different types do not correspond to their abundances in the meteorites these abundances are given in the legend (sources Alexander, 1993 Hoppe et al, 1994, 1996a Nittler et al, 1995 Huss et al, 1997 Amari et al, 2001a,b,c).

Be /3-decays to °B with a half-life of 1.5 Myr. Evidence for its former existence in the solar system is provided by excesses of B/"B correlated with Be/B ratio (Figure 4), first found within coarse-grained (type B) CAIs from Allende (McKeegan et al., 2000a). From the slope of the correlation line, McKeegan et al. calculated an initial °Be/ Be = (9.5 1.9) X lO at the time corresponding to isotopic closure of the Be-B system. This discovery was rapidly confirmed and extended by analyses of a variety of CAIs of types A and B, and a FUN inclusion from various... 

It may sound like a paradox, but currently, in optimizing for a parallel computer most of the effort should be spent on making sure that the individual node performance is as good as possible. This is a consequence of the power of the individual node compared to the network latency and bandwidth. In short, the current parallel machines are of large grain type. The parallel algorithm used should make every effort to communicate as seldom as possible. For a best performance it often means that a particular calculated value, needed on several nodes, can actually be recalculated more quickly on each node, compared to communicating it to the nodes where it is needed. This is the parallel form of the classic optimization trade-off between memory and CPU cycles.
