ABSTRACT
This paper presents a comparative study of the performance of multithreaded applications in different scenarios. These applications use the concept of threads to solve tasks. To make each scenario being evaluated were considered four factors: threads programming platform (or library), operating system, operating system architecture and the priority of running processes. We analyzed the performance obtained in mathematical applications in a multicore processor. The runtime operations and the number of parameters were used in comparative performance. Results showed that the factors referred to are actually relevant to the parallelism inherent to multicore architectures.
