Efficiency of programming model based on explicit creating light threads

The results of research of efficiency of execution of parallel programs created on the basis of the different programming models are presented. Programs run on an SMP formed a motherboard with few multi-core crystals. One programming model is based on the implicit to the user allocation of generated parallel threads on the provided SMP hardware resources and traditional approaches to the synchronization of threads. This model is represented by Open MP. The second model uses the explicit allocation of lightweights threads on resources SMP with the use of developed at Sandia National Laboratory library Qthreads.
