Today, Apple's designers, like their competitors, make machines that are almost disposable: the screens crack; the processors become outmoded.
The Centrino chips are also trying to deal with another, lesser-known, limiting factor in chipmaking: the smaller the processors become, the more power-hungry and the hotter they get (see chart 4).
If the number of available processors exceeds the degree of parallelism, the remainder of the processors become idle.
However, when an intermediate buffer is unavailable, the product remains blocking the processor until a downstream processor becomes available [6].
We replicate the information about the tree nodes on multiple processors ensuring that no single processor becomes overloaded.
As commercially available off-the-shelf processors become cheaper and faster, it is now possible to build a PC or workstation cluster that provides high computing power within a limited budget.
Data-access delay, not the processor speed, becomes the leading performance bottleneck of high-performance computing.
The resulting direct BEM proves to be efficient, robust and, in connection with proper pre- and post-processors, becomes an effective tool of engineering analyses just within the frequency limits given by the first two of the three spectral branches.
Such a hardware configuration (especially the case with two-processors) became widely spread in the last few years in the computer graphics area.
Such a hardware configuration (especially the case with two-processors) became widely available in the last few years thanks to low prices at present, but there is still a lack of parallel algorithms that are simple to implement and efficient enough to be an attractive alternative to existing serial algorithms.
