Following the tradition started a few years ago, the members of the Numerical Relativity Group and of the IT Department would like to invite you to the 2009 edition of the Cluster-Day@AEI. As in the past, the meeting is meant as a forum to exchange experiences in the use and management of High Performance Compute Clusters, as well as a way to report on new approaches and future strategies in the supercomputing world.
The meeting is planned on Thursday, 19th February, with a start at 9:15 am with a program that will run into the late afternoon (with a break for lunch).
The main theme of the event is: News to strategies of supercomputing.
The morning session will be reserved for the scientific projects with reports from the groups at the AEI, AIP, GWDG and hopefully additional reports from you or your colleagues. The afternoon session will be dedicated to presentations from companies about future supercomputing strategies.

Agenda Cluster Day 2009 at AEI (Print):
| 09:15 AM - 09:30 AM | Christa Hausmann-Jamin (AEI) | Welcome |
| 09:30 AM - 09:50 AM | Nils Dorband (AEI) |
Numerical Relativity on Damiana The numerical relativity group at the AEI is the main user of the Damiana cluster. I review our scientific projects that require the use of parallel computers, such as simulations of binary black holes and neutron stars. On the example of a typical run, I will discuss the type and amount of resources we require for our work. |
| 09:50 AM - 10:10 AM | Thomas Radke (AEI) |
Parallel numerical simulations with cactus

Der GoeGrid-Cluster wird in einem gemischten Nutzer-Umfeld betrieben. Sowohl Grid-Nutzer als auch
klassische Institutsnutzer haben Zugriff auf das System. Der Vortrag beschäftigt sich mit den verschiedenen
Aspekten dieser Konstellation. |
| 11:00 AM - 11:30 AM | Coffee Break | |
| 11:30 AM - 12:00 PM | Detlef Elstner (AIP) |
Experience with Lustre-Filesystem at AIP Two different implementations of the Lustre-Filesystem are compared. Some performance measurements are discussed. |
| 12:00 PM - 12:30 PM | Harry Enke (AIP) |
The AIP database cluster Based on a new approach to avoid the bottleneck of disk I/0 in modern computers, the GrayWulf architecture provides improved bandwidth and Amdahl numbers. |
| 12:30 PM - 01:00 PM | Karsten Kramer (PIK) |
A first glimpse at the new IBM iDataPlex Cluster @ PIK |
| 01:00 PM - 01:30 PM | Lunch Break∗ | |

| 04:30 PM - 05:00 PM | Andreas Hoheisel (Fraunhofer FIRST) |
Concurrent Workflows in Distributed Environments Within the D-Grid projects MediGRID, BauVOGrid and TextGrid the automation of loosely-coupled IT processes is done by the Grid Workflow Execution Service (GWES), which is based on the formalism of High-Level Petri Nets. The talk presents recent approaches for modeling and executing concurrent workflows on distributed Grid, Cluster or Web-Service environments in the context of these projects. |
| 05:15 PM - 05:45 PM | Peter Wegner (DESY) |
HPC activities at DESY, site Zeuthen |
| 05:45 PM - 06:00 PM | AEI | Summary |
| 06:00 PM - 06:30 PM | Come together | |
