Quadrics
At the heart of all HPC platforms are appropriate and stable interconnect (switch) fabrics. We have custom integrated cluster platforms utilizing most of the leading technologies and brands that have emerged within the past decade.
Across the full spectrum of performance (measured in sustained data throughputs,lower latencies, and CPU utilization levels) additional fabric considerations include: Node density, future scalability, and frankly budgets.
Is a new cluster being purpose built to primarily run specific codes 24x7x365, or will it be a broader research platform serving many Users? Are the primary applications/codes being run tightly or loosely coupled?
There are several fine interconnect fabric technologies in the HPC market. We can help you determine which one is best suited for "your specific" requirements.
InfiniBand
InfiniBand is a point-to-point high-speed switch fabric interconnect architecture that features built-in quality of service, fault tolerance and scalability. The InfiniBand Architecture (IBA) Specification defines the interconnect (fabric) technology for interconnecting processor nodes and I/O nodes to form a system area network that is independent of the host operating system and processor platform. See the InfiniBand Trade Association for more details on the InfiniBand specification and IBTA events.

Myricom
Myricom pioneered HPC interconnect technolgies with it's Myrinet-2000 technologies in the mid 1990s. Their newest Myri-10G protocol-offload solutions provide convergence between compute cluster and other enterprise assets running on Ethernet fabrics with near line-rate TCP/IP and UDP/IP throughputs (9.7-9.9 Gbits/s). Mryricoms Myri-10G NICs can be used with the MX (Myrinet Express) software for kernel-bypass operation for low latency and low host-CPU load over either Ethernet or Myrinet networks.
