Clinton, MA and Oslo, Norway, August 9, 2005E—Dolphin Interconnect today announced SuperSocketstm software library is now available to customers for high-performance computing applications interconnected with Dolphin SCI adapters. The SuperSockets tm Library enables standard Sockets to use the Scalable Coherent Interface (SCI) as a transport medium with its high bandwidth and extremely low latency

Dolphin has benchmarked a completed one byte socket send/socket receive latency at 2.31 microseconds. Benchmarks using netperf also show more than 255 MBytes (2035 Megabits/s) throughput using standard TCP_STREAM? Sockets. The SuperSockets tm software uses Dolphin’s SISCI API as its transport and most of the communication takes place in user space, avoiding time-consuming system calls and networking protocols. SCI remote memory access provides a fast and reliable connection.

“These record-setting performance benchmarks underscore the capabilities of the SCI standard as a high-performance interconnect,” said Kare Lochsen, CEO of Dolphin Interconnect. “Dolphin has extensive expertise in this technology having developed the first SCI-based interconnect soon after it became a IEEE standard in 1992, and we remain committed to keeping SCI at the most competitive performance levels in the future.”

SuperSockets tm requires no operating system patches or application modifications to run the software. SuperSockets tm is open source software available under LGPL/GPL and supports all popular Linux distributions for x86 and x86/Opteron. In Dolphin testing, the lowest latency was achieved using AMD Opteron (X86_64) processors. Support for UDP and Microsoft Windows is planned.

Dolphin SCI adapters are used to build server clusters for high-performance computing and in a wide range of embedded real-time computing applications including reflective memory, simulation and visualization systems, and systems requiring high-availability and fast failover.

FooBar GmbH (www.foobar-cpa.de), a software development and consulting firm with particular expertise in SCI and located in Chemnitz, Germany, assisted Dolphin in the development of SuperSockets tm.
