The seismic/seismology workgroup at the Freie Universität Berlin researches into the Earth's interior with the help of artificial and natural seismic waves. For this purpose, it developed a 3D imaging and modelling process which it applies in geotechnological and geodynamic projects on different depth scales. Two examples from the field of geotechnology: with the help of this process, a prediction range of up to 100 metres is possible during the build of the new Gotthard Basis Tunnel. Reservoirs up to five kilometres underground can be imaged and characterised. This is important when extracting petroleum and natural gas or for underground CO2 storage. By applying the process to geodynamic problems, the scientists want to improve research into the origin of large earthquakes. The Californian San-Andreas fault can thus be researched at a depth of ten kilometres and the Ocean plate under the South American Andes up to 100 kilometres. |
For a long time, the institute had to rely on reserving the necessary computing time and storage capacity either on the University's large mainframe computers or on the Beowulf cluster built by the institute. In the Spring of 2008, transtec installed a cluster with 13 Dual-Quad-core computing nodes and five Terabyte storage capacity. The plan is to expand this to 36 nodes by the start of 2009. With a total of 288 GB RAM, all the workgroup's calculations and simulations should be executed. In addition, 22 Linux workstations are in operation at the institute. |
"Our institute needs a reliable system with excellent computing power and a lot of storage capacity. We were impressed by transtec's expertise and the reliability of the hardware." "We were also extremely satisfied with transtec's consultation. In principle, we knew precisely what we needed in advance; but there was still room for optimisation. transtec recommended a 10 GB connection from the storage node to the switch which speeds up the data package transfer rate tenfold compared to a standard connection of just one Gigabit. We weren't sure if this was economically feasible. Thanks to the excellent advice we received from transtec, there was no danger of bottlenecking data transfer at this point.

The Dresden-Rossendorf Research Centre (FZD) has conducted application-oriented and basic research focussing on new materials, cancer research and nuclear safety research since 1992. Around 700 people are currently employed there. A high-performance IT system is imperative for the work performed at the Research Centre. Resource-intensive computations and simulations are run every day and experimental data is evaluated. For more than five years, the FZD has been using a high-performance cluster for these tasks. In 2006, the IT output was to be tripled by procuring an additional cluster. The new cluster is primarily used for performing sequential and parallel computations. The demands on processor output as well as memory, hard drive capacity and network performance are accordingly high. The FZD uses the Linux operating system. |
The current configuration of the transtec hydra high-performance cluster:

"What was convincing about the transtec offer was the price/performance ratio and – of equal significance – the manufacturer’s willingness to approach our individual demands in a very flexible manner. It goes without saying that a standard solution would not be of any use here. We need a tailor-made cluster solution. The hydra-cluster installed by transtec is utterly convincing. Our researchers make intensive use of the new possibilities: they can now run models and simulations in the area of nanostructures, for example, which were not possible in the past"

transtec‘s cluster solution for The University of Wales, Swansea
The situation:
The QCD Lattice Group at The University of Wales, Swansea, UK is one of the biggest groups in the UK. Its research activity is at the forefront of their field. A solution providing sufficient computing power for numerical simulations in the field of Quantum Chromodynamics was required as this in the past was achieved locally on the groups individual Workstations.
The challenge:
A high performance and scalable cluster was needed to calculate the amount of data. Due to the data exchanged between the compute nodes the solution required specifically low network latencies. The calculated results should be collated to a central point for further analysis. Also a Batch Queueing System was needed to optimize the load of the cluster.
The solution:
The system consists of a 15 node dual core Opteron cluster with a fast and low-latency network interconnection based on Infiniband. The master node running Scientific Linux 4 with Sun Grid Engine as Batch Queueing System for optimal load for the cluster. The nodes loading their operating system over the gigabit management network and running in a diskless mode. This makes the management of the nodes far easier. For parallel jobs, the cluster uses MPICH over gigabit network and MVAPICH for Infiniband. The monitoring and management is done by CluTo, the transtec Cluster Management Tools.

Solving equations with a huge number of variables requirering massive computing power |
LINUX HPC cluster with 50 nodes based on AMD Opteron Processors and a total of 108 GB main memory which includes a quad-processor node.
Networking is over two separate Gigabit networks.
The three master nodes are completely redundant and access a high-performance PROVIGO 660 Fibre Channel RAID system with 2.3 TB capacity. The result is an overall performance of 440 GFlops (peak) or 274 GFlops (Linpack). To ensure adequate cooling, the cluster is installed in room with an air-conditioning unit drawing 15kW. |
“There were three reasons for selecting transtec as a provider. First, the transtec contacts assigned to the project impressed us with their technical know-how and competence; second, and very important, transtec is in a position to provide all of the required hardware and software from a single source; third the price/performance ratio of the transtec products was high.“

Prof. Ralf Ludwig‘s basic research in theoretical physical chemistry involves extremely CPU- and storage-intensive computer simulations. In fact, they are so demanding that using the university’s computing centre to carry them out was not feasible. Having a suitable cluster system at his disposal was the ideal solution but wiring together a cluster out of conventional PCs would result in a system that was vulnerable to failure and that would have a large maintenance overhead.
The challenge: A highly stable, readily scalable cluster system was needed that could run uninterrupted for months on end. In addition, it was to be capable of carrying out Prof. Ludwig‘s computations without costly and time-consuming modifications. |
transtec installed a 64-bit dual-Opteron HPC cluster system delivering a peak performance of 230 GFlops. |
In vetting potential providers the price/performance ratio of the transtec HPC cluster proved decisive; in fact, transtec’s bid was the lowest of all. In addition, transtec was able to supply all desired hardware and its service offer was superior – factors, which provided the Rostock research, team with an attractively short installation lead-time. Since its installation a year ago, the transtec HPC cluster has been running virtually uninterrupted and without a hitch. Should problems arise, transtec cluster specialists Leonardo Lapeira, Dr. Andreas Koch and Anastassios Kazakidis will be available to lend assistance. „Our research group appreciated the fact that quality and customer support are taken seriously by transtec.“ Prof. Dr. Ralf Ludwig, University of Rostock. |

The cluster system installed by transtec at the University of Erlangen-Nürnberg was rated as one of five hundred fastest computers in the world when it went into operation eighteen-months ago. However, the growing computing needs of the engineering and scientific departments had brought the cluster to limits of its capacity. A decision was made to upgrade.
The challenge: transtec was commissioned to upgrade the university’s cluster system. It was stipulated that the upgrade should result in minimum interruption in user access and also maintain the integrity of the original system. |
• The new supercomputer, which is fully remotely administratable, consists of a total of 155 individual computers which function as compute nodes, frontends and file servers.
The configuration consists of:

“We were very satisfied with the performance of the original cluster, as well as with the availability of both hardware and software that it provided. The excellent support provided by transtec led to a close and fruitful co-operation and when the time came to upgrade transtec was our first choice.“
