Amdahl定律的推广及平行性的相关条件
A generalization of Amdahl's law and relative conditions of parallelism
摘要：
在这项工作中，我提出了一个概括的Amdahl定律的限制与许多处理器的并行实现。特别是我建立了一些数学关系，涉及处理器的数量和尺寸的处理问题，并与这些条件下，我定义的地面上可达到的加速比，一些类的并行实现。我还推导出一个条件，获得超线性加速比。所用的数学技巧是微分学。我描述了一些例子，从经典问题提供的专门文献的主题。
英文摘要：
In this work I present a generalization of Amdahl's law on the limits of a parallel implementation with many processors. In particular I establish some mathematical relations involving the number of processors and the dimension of the treated problem, and with these conditions I define, on the ground of the reachable speedup, some classes of parallelism for the implementations. I also derive a condition for obtaining superlinear speedup. The used mathematical technics are those of differential calculus. I describe some examples from classical problems offered by the specialized literature on the subject.
