"Boosting high-performance computing with optics"
JUNE 28, 2011, Gazettabyte

"IBM has adopted optical interfaces for its latest POWER7-based
high-end computer system. Gazettabyte spoke to IBM Fellow,
Ed Seminaro, about high-performance computing and the need for
optics to address bandwidth and latency requirements."
.....
"Using optical engines, each node - a specialised computing card -
has a total bandwidth of 224, 120 Gigabit-per-second (12x10Gbps)
VCSEL-based transmitters and 224, 120Gbps receivers. The interfaces
can interconnect up to 2,048 nodes, over half a million POWER7
cores, with a maximum network diameter of only three link hops.
IBM claims that with the development of the Power 775, it has
demonstrated the superiority of optics over copper for high-end
computing designs."
