| Summary: | This article sets the task to consider the most important details of installing and configuring the meta-package worker node (wn), which deploys on the computing node the necessary set of services responsible for performing tasks arriving at the grid site, and also conduct a series of tests after installing and configuring the meta-package wn on eligibility for running ATLAS (CERN) software. To solve this problem, a testing ground was formed and the serviceability of wn services was tested. The cloud segment of the data center of the Institute of Physics of the Azerbaijan National Academy of Sciences, which in turn is part of the cloud infrastructure of LIT JINR, was used as a testing ground. The testing site for computing nodes is a group of virtual machines running Scientific Linux 7, on which the wn meta-package was installed and configured, as well as the ATLAS experiment software needed to evaluate the performance of the tested nodes. The performance of the tested nodes was evaluated through the monitoring system of the data center of the Institute of Physics of the NAS of Azerbaijan on the basis of the ZABBIX platform, as well as by means of monitoring the ATLAS experiment (CERN) after directly including these nodes in the structure of the AZ-IFAN grid site. The most important details of installing and configuring the wn meta-package are shown. The obtained results demonstrate the effective performance of this meta-package on the computing nodes of the AZ-IFAN grid site. In addition, this article demonstrates the capabilities of the cloud segment, which created a testing ground for testing the wn metapackage at computing nodes, as well as a monitoring system for the data center of the Institute of Physics of the NAS of Azerbaijan.
