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:

Most of the software that is used to manage the Lisa system is Open Source. We are using the following software to manage the system:
The SURFsara Data Archive allows the user to safely archive up to petabytes of valuable research data.
Persistent identifiers (PIDs) ensure the findability of your data. SURFsara offers a PID provisioning service in cooperation with the European Persistent Identifier Consortium (EPIC).
B2SAFE is a robust, secure and accessible data management service. It allows common repositories to reliably implement data management policies, even in multiple administrative domains.
The Data Ingest Service is a service provided by SURFsara for users that want to upload a large amount of data to SURFsara and who not have the sufficient amount...
The Collaboratorium is a visualization and presentation space for science and industry. The facility is of great use for researchers that are faced with...
Data visualization can play an important role in research, specifically in data analysis to complement other analysis methods, such as statistical analysis.
