DKRZ, supported by IBM, took in its new Hierarchical Storage Management System based on a High Performance Storage Systems (HPSS). Experts from IBM/Global Technology Services have implemented the latest HPSS software and the Linux operation system by Red Hat on the IBM x86 server as well as a HPSS disk cache with five Petabyte.
The new system allows currently a transfer of climate data between the high performance computer and the archive system with a bidirectional bandwidth up to 12 Gigabyte per second, increasing up to 18 Gigabyte per second in autumn 2015.
The system manages all archived simulation data at DKRZ and serves as the central in- and output interface of the tape library.
Hamburg, May, 8th, 2015: The German Climate Computing Center (DKRZ), supported by IBM, took in operation the first configuration level of its new Hierarchical Storage Management System (HSM) that is based on a High Performance Storage Systems (HPSS). The system manages all archived simulation data at DKRZ and serves as the central in- and output interface of the tape library.
Already in autumn 2014, experts from IBM/Global Technology Services have implemented the latest HPSS software and the Linux operation system by Red Hat on the IBM x86 server as well as a HPSS disk cache with five Petabyte. The size of the disk cache, which serves as a temporary buffer, corresponds to the storage capacity of 5,000 well equipped notebook computers.
IBM specialists have migrated the data of the former, significantly smaller HPSS system to the new system within only two days of operational interruption. The new system with an essentially higher sustained throughput (in- and output) allows a transfer of climate data between the high performance computer and the archive system with a bidirectional bandwidth up to 12 Gigabyte per second. Until autumn 2015 the system will be once more upgraded to a bandwidth up to 18 Gigabyte per second (peak).
At the moment the tape library at DKRZ contains about 20 million data with a data volume of 40 Petabyte. Using HPSS DKRZ will be able to handle the massive data growth in the climate research. Within the next five years a data production of annually 75 Petabyte and a total volume of 500 Petabyte is expected, appropriate to the estimated growth of data production on the new high performance computer system for earth system research 3 (HLRE-3) being currently installed at DKRZ.
The upgrade of the HSM system is part of the project HLRE-3 that is funded with 41 million euro – two thirds by the Federal Ministry of Education and Research and one third by the Helmholtz Association. The financial resources are passed on to DKRZ by the Helmholtz Center Geesthacht – Center for Materials and Coastal Research.
HPSS results from a 20 years lasting cooperation between IBM and the five national US-Laboratories of the Department of Energy (DOE): Lawrence Livermore, Los Alamos, Sandia, Lawrence Berkley and Oak Ridge (further information: www.hpss-collaboration.org ).
HPSS is implemented for very large scientific data archives at research facilities and universities, for weather forecast systems as well as in the field of defense and national security. Organizations with CPU- and data intensive processing use HPSS. In Europe and Germany it is used among other by the European Centre for Medium Range Weather Forecasts (ECMWF), the Karlsruhe Institute for Technology (KIT), the German Meteorological Service (DWD) and the computing center Rechenzentrum Garching of the Max Planck Society (RZG).

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
