Resum
In this paper we are going to compare the performance obtained with the hybrid programming models MPI+SMPSs and MPI+OpenMP, especially when executing with a Dynamic Load Balancing (DLB) library. But first we will describe the SMPSuperscalar programming model and how it hybridizes nicely with MPI. We are also explaining the load balancing algorithm for hybrid applications, LeWI, and how it can improve the performance of hybrid applications. We will also analyze why SMPSs is able to exploit the be...
