Observed Speedup

Observed speedup of a system which has been parallelized, is defined as:

Granularity is one of the easiest and most extensively used indicators for a parallel program's performance.

Parallel Overhead

The amount of time required to direct parallel tasks, as opposed to responsibility useful work. Parallel overhead can consist of factors such as:

  • Synchronisations
  • Task start-up time
  • Data communications
  • Software overhead forced by parallel compilers, tools, , libraries, operating system, etc.
