During August 2014 HLRS and Cray will install “HORNET” the follow-up to HERMIT. HORNET is a Cray XC40 with 3944 compute nodes. It is based on a new* processor and the Cray Aries network. The system will have some* cores, a peak performance of a few* PFLOP/s and a main memory of 493 TByte.

* for legal reasons, we currently do not announce technical details.

The first day is targeted to HERMIT users who will continue their work on HORNET. Specialists from Cray will talk about the hardware and software enhancements between the XE6 and XC40 in order to support your migration towards this new machine.

The second day is dedicated to user parallel IO at scale. Topics are I/O hardware aspects, parallel filesystems, several I/O strategies, serial I/O optimization, and I/O APIs such as MPI-IO, NetCDF, papallel-netCDF, HDF5, SIONLib, and ADIOS. Most of the discussed topics are independent of the specific hardware at HLRS.

The third and fourth day covers a 2 day introduction workshop about porting and optimizing your application for the Cray XC40. The topics of this workshop include the Cray Programming Environment, scientific libraries and profiling tools.  

HERMIT is available in Germany and Europe through this link.Note that new name XC40 = XC30 with Haswell processors (old name).
