Popis

FUNCTION: The Laboratory for Computational Physics and Fluid Dynamics (LCP&FD) is in round-the-clock production for computational studies in the fields of compressible and incompressible fluid dynamics, reactive flows, fluid-structure interaction (including submarine, ship, and aerospace applications), plasma physics, atmospheric and solar magnetoplasma dynamics, application of parallel processing to large-scale problems such as unstructured grid generation for complex flows, and other disciplines of continuum and quantum computational physics. DESCRIPTION: The facility is used to develop and maintain state-of-the-art analytical and computational capabilities in fluid dynamics and related fields of physics, to establish in-house expertise in parallel processing and online graphical rendering for large-scale scientific computing, to perform analyses and computational experiments on specific relevant problems, and to transfer this technology to new and ongoing projects through cooperative programs. INSTRUMENTATION: 1120-core x86 cluster Two 64-core SGI Altix systems 184-core x86 cluster 256-core SGI ICE cluster 256-core Opteron cluster More than 60 SGI, Apple, and Intel workstations Each system has on the order of 14 terabytes of disk for storage during a simulation. All computers and workstations have network connections to NICENET and ATDnet allowing access to the NRL Center for Computational Science facilities (including the DoD HPC resources) and many other computer resources both internal and external to NRL.
