A study of multicore processor performance for network applications

Abstract

Multicore processors have become the new approach for increase newlinein the performance of the processor based systems General purpose multicore newlineprocessors that are also multithreaded are being used in various applications newlineby virtue of their capability in handling various processing requirements For newlinea given application the improvement in performance of the system is newlineobtained by optimizing the code for execution and effectively allocating the newlineCPUs to the parallelized and or the pipelined processes newlineParallelization is an optimization technique to enhance the newlineperformance of the system Parallelization reduces the total execution time newlinethat is dependant on the number of cores used Programming of the newlinemultithreaded multicore processor needs a thorough understanding of the newlinehardware and the effective use of the Application Program Interface API for newlineparallel programming Number of CPUs per core the common resources newlineshared by these logical CPUs for the application and the complexity of each newlineprocess in the functional pipeline are considered for allocation of the number newlineof CPUs to be allocated for each of the functional stages newline
