Abstract Supercomputer job management systems (JMS) are complex software which have a number of parameters and settings. Various simulating methods have been used in order to explore impact of such parameters on the JMS efficiency metrics. At the same time evaluating accuracy (adequacy) of the applied JMS models is one of the key points. The paper contains the results of adequacy measure experiments for various JMS models, including simulating with a virtual supercomputing nodes and with the Alea job scheduling simulator. JMS SUPPZ functioning at the Joint Supercomputer Center of the Russian Academy of Sciences (JSCC RAS) was used for the experiments. Source data for such simulating was created upon the statistics of supercomputer MVS–10P OP installed at JSCC RAS. The normalized Euclidean distance between the job residence (turnaround) time vectors, obtained from the job streams of the real supercomputer and JMS model, was used as a measure of adequacy. The experiments results have confirmed intuitive ideas about the studied simulating methods accuracy, that allows using the normalized Euclidean distance between the jobs turnaround times vectors as a measure of various JMS models adequacy.
