ALSO CALLED: I/O Architecture, System IO, IO Architecture, Infiniband, and System I/O
DEFINITION: InfiniBand is a type of communications link for data flow between processors and I/O devices that offers throughput of up to 2.5 gigabytes per second and support for up to 64,000 addressable devices. Because it is also scalable and supports quality of service (QoS) and failover, InfiniBand is often used as a server connect in high-performance computing (HPC) environments. The internal data flow

Maintaining High Performance in a Cloud
sponsored by Platform Computing Corporation
WHITE PAPER:
In this paper we demonstrate the concept of High Performance Computing in a cloud and show that HPC clouds can deliver the needed utilization and scalability on par with the current native HPC approach of designing dedicated systems for specific applications.

INFINIBAND ARCHITECTURE DEFINITION (continued): … system in most PCs and server systems is inflexible and relatively slow. As the amount of data coming into and flowing between components in the computer increases, the existing bus system becomes a bottleneck. Instead of sending data in parallel (typically 32 bits at a time, but in some computers 64 bits) across the backplane bus, InfiniBand specifies a serial (bit-at-a-time) bus. Fewer pins and other electrical connections are required, saving manufacturing cost and improving reliability. The serial bus can carry multiple channels of data at the same time in a multiplexing signal.
