Explanation
This graph compares a serial computer (typical workstation) with a
cluster of workstations (similar type). The logarithmic QUIPS is plotted
on the y-scale. The
cluster has high startup overhead and the overhead increases with the
number of the nodes in the cluster. The above graph shows us the
scalability of the cluster. It shows that in case an application
stresses small subtasks and rapid control changes (i.e it falls in the
left hand side of the serial curve) to fit in the cache, it is better to
use a single computer.
