The simulation model of the computer cluster

Simulation is often used in cases when it is impossible to carry out experiments with real complex objects. The article represents the description of the computer cluster simulation model. Parameters, which affect the cluster performance, were selected, a simulation model was designed, and experiments were conducted. The obtained model allowed finding the optimal variant of the cluster performance, which consists of five computers

A Technique for Assessment of Parallelism of Specialized Test Variants Using Statistical Methods

The paper offers a technique for evaluation of parallelism of ongoing student assessment test variants on the basis of statistical methods through the example of tests in mathematics. The authors analyze the test results of National Research Tomsk Polytechnic University students and make adequate conclusions regarding parallelism of text variants
