CRAY XE6 (Hermit)
Installation ste
p 0 has been integrated into step 1 and is not longer accessible as separate system.
Hermit will be installed in 3 steps. The major purpose of step 0 was to perform tests, migrate applications and integration of the new system into the HLRS environment.
Installation step 1 is currently installed and is available to users since December 2011.
The installation step 1 is based on CRAY XE6 technology and consists our of 3552 compute nodes.
The overall system concept will have beside the compute nodes additionally special frontend nodes for pre- and postprocessing in different configurations and a huge and fast storage system.
ISV codes are supported to a large extent directly on top of the Cray Linux Environment (CLE) or by using the Cluster Compatibilty Mode (CCM).
A further installation step is planned for 2013 and will be fully integrated with the phase 1 system.
