Scalability of the Application
Scalability: measures the effort needed to maintain current efficiency, if possible, when the system increases.
Efficiency E= Speedup/ p = 1/ (1+ To/Work)
To--sum of overhead on p processors
The isoefficiency function determines at what rate the problem size needs to be increased with respect to the number of processors in order to maintain a fixed efficiency
