TITLE: INTEGRATION, DEVELOPMENT AND PERFORMACE OF THE 500 TFLOP HETEROGENEOUS CLUSTER (CONDOR)

LARTS 218, 4:30 - 5:30

ABSTRACT:

The Air Force Research Laboratory Information Directorate Advanced Computing Division (AFRL/RIT) High Performance Computing Affiliated Resource Center (HPC-ARC) is host to a very large scale interactive computing cluster consisting of 1800 nodes. CONDOR, the largest interactive Cell cluster in the world, consists of integrated heterogeneous processors of IBM Cell Broadband Engine multicore CPUs, nVidia GPGPUs and powerful Intel x86 server nodes in a 10GbE Star Hub network and 20Gb/s Infiniband Mesh, with a combined capability of 500 Teraflops. Applications developed and running on CONDOR include computational intelligence computing, video synthetic aperture radar (SAR) backprojection, Space Situational Awareness (SSA), video target tracking, linear algebra and others. This presentation will discuss design and integration of the system. It will also show progress on performance optimization using the heterogeneous cluster and lessons learned on scalability using heterogeneous architectures.
