RTU HPC cluster “Rudens” consists of 54 computing nodes for job execution and one head node which performs cluster management function. All nodes are inter-connected with fast InfiniBand network. Each compute node is equipped with two x86_64 architecture processors (CPUs), and some of the nodes additionally with 2 or 4 Nvidia Tesla graphical accelerators (GPU). Cluster architecture is heterogeneous, combining nodes of different generations and technical parameters.
Several network-attached storage systems are available for storing user data with a total capacity of ~800 TB. For tasks with intensive I/O, a special NVMe disk array with BeeGFS parallel file system is available.
Users connect to a separate login node which provides a work environment and tools for running jobs in the cluster. Job management is provided by Torque/Moab tools.
