    This article belongs to the Special Issue Parallel Computer and Parallel Algorithms
    Abstract: Parallel principles are the most effective way how to increase performance in parallel computing (parallel computers and algorithms too). In this sense the paper is devoted to a complex performance evaluation of matrix parallel algorithms (MPA). At first the paper describes the typical matrix parallel algorithms and then it summarizes common proper... Show More

    This article belongs to the Special Issue Parallel Computer and Parallel Algorithms
    Abstract: Parallel principles are the most effective way how to increase parallel computer performance and parallel algorithms (PA) too. In this sense the paper is devoted to a complex performance evaluation of chosen PA. At first the paper describes very shortly PA and then it summarized basic concepts for performance evaluation of PA. To illustrate the ana... Show More

    This article belongs to the Special Issue Parallel Computer and Parallel Algorithms
    Abstract: The optimal resource allocation to satisfy such demands and the proper settlement of contention when demands exceed the capacity of the resources, constitute the problem of being able to understand and to predict system behavior. To this analysis we can use both analytical and simulation methods. Modeling and simulation are methods, which are commo... Show More
