The Lisa system is a cluster computer consisting of several hundreds of multi-core nodes running the Linux operating system. The system is installed and maintained by SURFsara.
The Lisa system is used for the SURFsara service Research Capacity Computing Services (RCCS). RCCS is a SURFsara compute service for researchers coping with many large computational tasks. RCCS covers computing tasks which are typically characterized by a large amount of independent, moderately parallel, computing tasks. The tasks itself can be run in parallel on the computing system. RCCS is typically for those compute tasks which in practice cannot be run on either departmental or university computing systems, due to their size.
The following participants are involved in the Lisa system:
The Lisa system is constantly evolving and growing to satisfy the needs of the participants. At this moment the configuration is as follows:
