- About us
Goliath Cluster uses an HTCondor batch-processing system for distributing tasks to individual computational servers. HTCondor servers receive tasks from both local and grid users and distribute them to working nods. The working nods are divided into subclusters according to the type of their hardware. Minis, Lilium, Mahagon, Mikan, Magic, Aplex, Malva, Ib and Ibis. More >>
The Computing Centre of the FZU ensures the operation of up to several computer clusters and disk servers, which are connected within national and international grid projects.
The largest cluster called Goliath was providing approx. 10000 logical (5000 real) computational cores at the beginning of 2021. The cluster has been adding new servers gradually, therefore it contains newer and older CPU versions from Intel and AMD. Together with disc servers with the total capacity of over 5 PB (January 2021), it is participating in an international EGI grid within the WLCG project (distributed data processing for experiments on the LHC accelerator) as well as in an OpenScience grid (primarily intended for projects in the US). Due to a cooperation with national eINFRA e-Infrastructure, it has an excellent external connection (100 Gbps to private network of the LHC project, and 40 Gbps to the Internet).
We administer all servers using Puppet, we store any changes in Git. An extensive local monitoring is assured by Nagios and Prometheus, the visualization by munin a Grafana. The distribution of tasks to servers is ensured by the HTCondor batch-processing system. Usage statistics are published on the EGI portal. The calculation capacity is expanded by adding a functional forwarding function of selected tasks to the national IT4I supercomputer centre and the expansion of the storage room is performed on CESNET resources.
