Moab Cluster Suite from Cluster Resources is an advanced workload manager and scheduler capable of optimizing scheduling and node allocation decisions. The software will allow BSC to gain extensive control over which jobs are considered eligible for scheduling, how the jobs are prioritized and where the jobs will run.
Moab also simplifies and unifies management and acts as a flexible policy engine that guarantees service levels and speeds job processing. Moab will be used as an external scheduler for the SLURM resource manager. SLURM, developed at Lawrence Livermore National Laboratory and Hewlett-Packard, is an open-source resource manager utilized on some of the most powerful supercomputers, such as BlueGene/L and ASC Purple.
The combination of Moab and SLURM will optimize the system performance of MareNostrum, allowing BSC to more efficiently conduct all scientific projects. Both tools will be deployed and installed by February.
“One of the important characteristics of the Moab-SLURM solution is its ability to handle applications simultaneously running across very large number of MareNostrum’s processors and using a large number of processors is key to BSC’s users,” said Sergi Girona, Operations Director of BSC. “The BSC’s Computer Sciences Department has also a lot of expectations with Moab because it allows dynamic integration and evaluation of new scheduling and resource allocation algorithms.”
MareNostrum’s adoption of Moab continues the trend of the largest and most powerful supercomputers in the world adopting Moab, as currently 5 of the top 6 systems on TOP500 have Moab. Leading supercomputing centers currently using Moab include the Sweden National Supercomputer Center, the National Center for Supercomputing Applications (NCSA), Lawrence Livermore National Laboratory, and CERN (European Organization for Nuclear Research).

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...
