Simultaneous multithreading represents an attractive option for mainstream processors because it providesa smooth migration path from today’s computer usage patterns. Because the impact on single-thread execution is low and thenegative impact on performance in the worst case will be nearly unnoticeable. A user need only have multiple threads orapplications running a small fraction of the time to overcome that cost. Simply threading the operating system may beenough to produce noticeable improvements in that scenario. This thesis discusses about the threading tool which evolvestotal eight machines with multiple number of cores with different system specifications for calculating execution time. Sixdifferent tasks i.e. LU Decomposition, Ordinary Differential Equation, Fast Fourier Transform, sparse, 2-D and 3-D areperformed on all the machines and results has been presented. It is observed that multithreading leads to tune theapplication performance considerably. In this thesis we have presented a comparative study of multicore and multiprocessorsystems based on power and performance. Each type of architecture is suitable for different type of task execution.Architecture utilized by multicore processor could process multiple instructions at very fast speed of a single huge code andimproving execution speed whereas a multi-processor is capable of executing multiple programs in parallel and speeding upexecution.
