The paper presents modeling of performance and power consumption when running parallel applications on modern cluster-based systems. The model includes basic so-called blocks representing either computations or communication. The latter includes both point-to-point and collective communication. Real measurements were performed using MPI applications and routines run on three different clusters with both Infiniband and Gigabit Ethernet interconnects. Regression allowed to obtain specific coefficients for particular systems, all modeled with the same formulas. The model has been incorporated into the MERPSYS environment for modeling parallel applications and simulation of execution on large-scale cluster and volunteer based systems. Using specific application and system models, MERPSYS allows to predict application execution time, reliability and power consumption of resources used during computations. Consequently, the proposed models for computational and communication blocks are of utmost importance for the environment.
