Golias farm
The Golias farm uses the HTCondor batch system for distributing jobs to individual computing servers. HTCondor servers accept jobs from local and grid users and distribute them to worker nodes. Worker nodes are divided by hardware type into subclusters: Milan, Minis, Mahagon and Mikan.
Overview table of subclusters and their main parameters (July 2023):
