It’s important to keep in mind there are no one-size-fits-all solutions Read more…

Austrian HPC Consortium Meets Demanding Inter-node Communication Challenge with Intel True Scale Fabric

Aug 6, 2014 |

The Vienna Scientific Cluster (VSC) refers to a collaboration of high-performance computing resources designed to support a consortium of multiple institutions in Austria consisting of the University of Vienna (UNVIE), the Vienna University of Technology (TUVIE), the University of Natural Resources and Applied Life Sciences Vienna (BOKU), the Graz University of Technology (TU Graz), and Read more…

Low Effort Porting Gives Great Scaling of Seismic Code on Numascale Shared Memory Cluster

Aug 4, 2014 |

Numascale and Statoil have initiated a collaboration to optimize OPM for Numascale systems. The original OPM code showed poor scalability even within a single node. With very limited effort, the collaboration was able to obtain almost linear scaling across an entire Numascale system. The configuration enables simulation of entire oilfields with fine grid resolution. The Read more…
