Obviously, an execution time of 10 years is always unreasonable.

Examples. Modeling large DNA This equation is known as Amdahl's law.

Even with infinite. Pitfall: Amdahl's Law. Improving an aspect of a computer and expecting a proportional improvement in overall performance.

Example: multiply accounts for 80s. In computer architecture, Amdahl's law (or Amdahl's argument) is a formula which gives the (April ) (Learn how and when to remove this template message) For example, if a program needs 20 hours using a single processor core, and.

An implication of Amdahl's law is that to speedup real applications which have both serial and parallel portions, heterogeneous computing techniques are required. An example is a computer program that processes files from disk. I agree.

Amdahl's law is often used in parallel computing to predict the theoretical speedup when using multiple processors.

An implication of Amdahl's law is that to speedup real applications which have both serial and parallel portions, heterogeneous computing techniques are required. In computer architectureAmdahl's law or Amdahl's argument [1] is a formula which gives the theoretical speedup in latency of the execution of a task at fixed workload that can be expected of a system whose resources are improved.
