The Nuclear Engineering Division has three Beowulf clusters as its advanced computational Multiple-Instruction Multiple-Data platform for performing computations of engineering mechanics, fluid dynamics, Monte Carlo simulations and engineering analysis. The three clusters are comprised of one 78 single core node Ethernet, a 46 multicore (368 cores) Infiniband, as well as a 5 node multicore/large memory (80 cores/128GB per node) Infiniband cluster.

The front-end servers have both Intel Xeon and Opteron processors and one front end node is a large memory system with 198 GB of RAM for CFD Meshing. The compute nodes have a variation by cluster of both Intel Xeon processors running as well as Opteron.

The two multicore clusters have their file systems provided by a new high performance fileserver from PANASAS (PAS 8).

The operating system's primarily used on the cluster are CentOS 5.

Compilers:

PGI Workstation 3.1 (F77, F90, HPF, C++, C), Intel Fortran Pro, Absoft F90 Pro, MPI.

Applications

The following applications have been ported to the cluster:

• CFX,
• IMPACT21,
• MESHLESS,
• Monte Carlo,
• NEPTUNE,
• Star-CD,
• Star-CCM+,
• Matlab,
• COMSOL,
• Fluent,
• Abaqus and
• Transims.
