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).

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
