Abstract**: **There are different techniques
to make parallel programs. In parallel programming, independent pieces of tasks
that may run in parallel. The objective of parallel algorithm design is to
develop parallel computational methods that run very fast with as few
processors as possible. A proper implementation expected to give a better speedup
in dual core machine and in a quad core machine. In this paper, the
implementation of different parallel algorithms such as Naive Algorithm , Brute Force Algorithm , Graham
Scan Algorithm on geometric problems is presented.
