HPC Advisory Council High-Performance Center offers an environment for developing, testing, benchmarking and optimizing products based on clustering technology. The center, located in Sunnyvale, California, provides on-site technical support and enables secure sessions onsite or remotely.
The High-Performance Center provides a unique ability to access the latest systems, CPU, and networking (InfiniBand/10GigE) technologies, even before it reaches the public availability. It provides a development testing and tuning environment for applications.
The clusters utilize 'Fat Tree'(or Constant Bisectional Bandwidth - CBB) network architecture to construct non-blocking switch configurations. Fat Tree network is a switch topology in which integrated non-blocking switch elements (crossbars) with a relatively low number of ports are used to build a non-blocking switch topology supporting a much larger number of endpoints. Using full Fat Tree networks is a key ingredient to deliver non-blocking bandwidth for high performance computing and other large scale compute clusters.
