NYSE Euronext Advanced Trading Solutions Delivers US Equities in a Box

NYSE Euronext Advanced Trading Solutions, a world leader in low latency trading technology and division of NYSE Euronext (NYX), today announced an innovative software based solution that has the capability to comfortably handle 10 major US equities feeds on a single server with potential headroom of 3x current market peak capacity. The key ingredients of this implementation were its flagship high performance middleware, Wombat Data Fabric™ and its feed handler technology.

A representative selection of NYSE Euronext Advanced Trading Solutions’ off-the-shelf feed handlers covering the major US equities markets was chosen to highlight the scalability and performance of the solution on industry standard hardware. An alternative selection from the 150+ suite of global feed handlers which cover all geographies and asset classes could be used in this solution stack.

NYSE Euronext Advanced Trading Solutions demonstrated breakthrough performance by publishing and consuming a full-day of data from ten major US equity feeds on a 24 core system using Intel’s recently launched Xeon® 7400 "Dunnington” processor. Wombat Data Fabric’s memory-sharing architecture makes it possible to run a day of US equities data simultaneously on a quad-socket, 24-core Intel Xeon server. Even at market open and close peaks, CPU utilization remained under 40 percent, with average transport latency of less than 10 microseconds.

"The performance of this solution demonstration bodes well for any financial services organization concerned with latency and the amount of hardware typically needed to process market data and other high volume messaging loads in the capital markets,” remarked Conor Allen, VP Technology, NYSE Euronext Advanced Trading Solutions. "Wombat Data Fabric’s Local Direct Memory Access (LDMA) transport provides single digit microsecond latency between processes on the same machine bypassing the I/O stack. This solution is particularly suited to co-location applications.”

Based on Intel’s 45nm high-k process technology and reinvented transistors that use a Hafnium-based, high-k metal gate formula, the new Xeon® 7400 series, with up to six processing cores per chip and 16MB of shared cache memory, delivers nearly 50 percent better performance in some cases than its predecessor with lower power consumption.

"Wombat Data Fabric is clearly taking advantage of the performance available from our multi-core platforms,” states Nigel Woodward, Intel’s Worldwide Director of Financial Services. "This is an impressive example of how the industry can use Intel multi-core technology to keep pace with growing trading volumes.”

Wombat Data Fabric™ is fully integrated with the widely used MAMA API. As a result, all NYSE Euronext Advanced Trading Solutions applications, including 150+ feed handlers, DART Entitlements™, and SuperBook™, are supported on Wombat Data Fabric, and the hundreds of customer applications written to MAMA 4.0 API can be ported across to Wombat Data Fabric without any need for code changes.

Feeds used in this solution demonstration: NYSE OpenBook; NYSE ArcaBook; SIAC CTA; CME MDP Index Futures; Direct EDGE; BATS ECN; Nasdaq OMX TotalView; NASDAQ OMX UTP; NASDAQ OMX TDDS and NASDAQ OMX NDDS.
