GUIDE TO THE IBM p690 Regatta

This page is the main entry point to the support pages of the IBM p690 Regatta Turbo system at Parallab. Answers to many frequently asked questions can be found here. We will do our best to keep these pages up-to-date. Please read and consult these support pages regularly, especially when you have just started using the machine.

The name of the IBM p690 Regatta system is: tre.bccs.uib.no

The system is available to staff and students from the University of Bergen, researchers that obtained quota through the NOTUR programme, staff and students from the Institute of Marine Research (Havforskningsinstituttet), and staff and students from the Nansen Environmental and Remote Sensing Center (Nansensenteret). In addition, the system is available to Parallab partners through EU and other projects.

User support. Questions and problems can be reported to hpc-support@hpc.uib.no or support-uib@notur.no and they will be handled as soon as possible. Working hours are roughly Monday-Friday 08:00-16:00.
