A new world record aggregate bandwidth peak of 101.13Gbps has been set by a team led by the Stanford Linear Accelerator Center (SLAC), CalTech and Fermi National Accelerator Laboratories (FNAL) using Sun FireTM V20z servers based on the AMD Opteron processor running the SolarisTM 10 Operating System (Solaris OS) and Linux.

Obtained during the SCInet Bandwidth Challenge at Supercomputing 2004, SLAC demonstrated completely filling a 10Gbps transcontinental network path for a sustained time with standard 1500Byte packets, and the team achieved over 15Gbps (9.43Gbps in one direction and 5.65Gbps in the reverse direction simultaneously) on a single 10Gbps wavelength path. Last year's record for this challenge was set at 23.21Gbps.

The team also was able to show smooth communications at multi-Gbps rates between multiple operating systems and different vendor Network Interface Cards.

The SCInet Bandwidth Challenge encourages participants to push the envelope in terms of network throughput in high performance computing.

"Challenges like this demonstrate the emerging maturity and robustness of the 10Gbps market," said Dr. Les Cottrell, assistant director for SLAC Computing Services, "and opens up the possibility for new ways to increase the amount of research we can conduct in our computing centers while reducing our total cost of ownership."

These challenge results are evident of the efficiency and robustness that an operating system can deliver along with the power and flexibility of Sun's two and four-way servers built with the AMD Opteron processor and 10 gig Ethernet cards from S2IO and Chelsio.

These performance achievements demonstrated an increase in overall throughput and how one Sun FireTM V40z server could achieved I/O Ethernet performance of nearly 12Gbps when configured with Solaris 10 OS and two S2IO network cards. "Blistering TCP/IP network performance with Solaris 10 allowed this collaborative effort between S210, Chelsio and SLAC to blow away previous records," said Glenn Weinberg, vice president of the Operating Platform Group at Sun. "Our investment in Solaris 10, the most advanced UNIXR operating system ever, is paying off for customers worldwide."

The Solaris 10 OS is the fastest operating system ever released by Sun. With its support, applications can run up to 30 times faster and Web server performance is more than 40 percent faster than the Solaris 9 OS in Web server performance on both SPARCR and x86 systems. Sun plans to offer the Solaris 10 OS available as a free download by January 31, 2005.
