Abstract:

The Air Force Research Laboratory Information Directorate Advanced Computing Division AFRLRIT High Performance Computing Affiliated Resource Center HPC-ARC is the host to a very large scale interactive computing cluster consisting of about 1800 nodes. Condor, the largest interactive Cell cluster in the world, consists of integrated heterogeneous processors of IBM Cell Broadband Engine Cell BE multicore CPUs, NVIDIA General Purpose Graphic Processing Units GPGPUs and Intel x86 server nodes in a 10Gb Ethernet Star Hub network and 20Gbs Infiniband Mesh, with a combined capability of 500 trillion floating operations per second TFLOPS. Applications developed and running on CONDOR include large-scale computational intelligence models, video synthetic aperture radar SAR back-projection, Space Situational Awareness SSA, video target tracking, linear algebra and others. This presentation will discuss the design and integration of the system. It will also show progress on performance optimization efforts and lessons learned on algorithm scalability on a heterogeneous architecture.
