Parallel Programming Environment Characteristics

 The parallel programming environment consists of an debugger, a editor,  performance evaluator and programme visualizer for improving the output of parallel computation. All programming environments have these tools in single form or the other. Based on the features of the available tool sets the programming environments are categorize as basic, limited, and well developed.  The Basic environment gives simple facilities for debugging and program tracing. The limited integration facilities give some additional tools for performance evaluation and parallel debugging. Well-developed environments give most advanced tools of debugging programs, for textual graphics interaction and for parallel graphics handling.

There are certain parallel overheads associated with parallel computing. The parallel overhead is the quantity of time needed to coordinate parallel tasks, as opposed to doing useful work. These includes in the following factors:

i)    Task start up time

ii)   Synchronisations

iii)  Data communications.
