Web2.6.2 Amdahl's law Back in the 1960s, Gene Amdahl made an observation [3] that's become known as Amdahl's law. It says, roughly, that unless virtually all of a serial program is parallelized, the possible speedup is going to be very limited—regardless of the number of cores available.

Speedup and amdahl's law

WebAmdahl’s Law¶. Amdahl’s Law is a formula for estimating the maximum speedup from an algorithm that is part sequential and part parallel. The search for 2k-digit primes illustrates this kind of problem: First, we create a list of all k-digit primes, using a sequential sieve strategy; then we check 2k-digit random numbers in parallel until we find a prime. WebIn computer architecture, Amdahl's law (or Amdahl's argument) 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. It is named after computer scientist Gene Amdahl, and was presented at the AFIPS Spring Joint Computer Conference in …
