CRAY XC30 (Hornet)

Starting on August 13th 2014 HLRS installed a new Cray XC30 system.

We expect this system (code named “Hornet”) to go into acceptance in September and be operational in November.

The new Cray XC30 Hornet is based on a new Intel Haswell Processor and the Cray Aries network. 

HLRS has already installed a small test system early this year and we have not seen problems with moving applications from the current XE6 system to the new XC30. Therefore, we do not expect to see major problems moving our users to the new system. We currently plan to have an overlap of the XE6 (Hermit) and the XC30 (Hornet) of about 3 months.

For the migration of users we will automatically transfer account information to the new system. Hermit and Hornet will access the same file systems such that users will not have to transfer any data.
