During August 2014 HLRS and Cray will install “HORNET” the follow-up to HERMIT. HORNET is a Cray XC30 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 XC30 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 XC30. 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.

If you cannot come to the course, please send an email to the organizer as soon as possible. This would allow us to accept additional participants from the waiting-list. There is no cancelation fee.
NO-SHOW: Registered persons that do not cancel and do not show up without any reasons are blocked for the next year on any of our workshops (because it is to expensive to produce unused copies of the slides for them).
|Limit||Maximum of 50 participants in Stuttgart (according to the seats in the rooms).|
|Handouts||Each participant will get a paper copy of all slides.|
