Advanced Clustering Technologies' Product Line Makes a Leap in Performance By Utilizing Quad-Core AMD OpteronTM Processor Technology

Kansas City, KS -- 9/10/2007 -- Advanced Clustering Technologies joins AMD (NYSE: AMD) today in a collaborative effort to announce the release of Quad-Core AMD Opteron TM processors. Introduced as an industry-defining native quad-core microprocessor, the quad-core technology continues AMD’s tradition of energy efficiency, performance, and virtualization leadership. Upon its release, Advanced Clustering Technologies will incorporate the option to utilize this technology into its Linux-based high performance computing product line.

Quad-Core AMD Opteron processors go far beyond simply adding two more cores; they present a native multi-core architecture where all four cores are on one piece of silicon. More than just four cores, Quad-Core AMD Opteron processors feature Direct Connect Architecture. This means you have processors directly connected to one another as well as the I/O and memory subsystem also directly connected to the processor. This helps reduce bottlenecks inherent in the traditional front-side bus architecture for better performance in the same thermal envelopes as previous AMD Opteron processors.

“We're very excited to see new technology entering the market that fills the gap for many of our clients who require faster clock speeds as well as high memory bandwidth,” said Shelly (Matthews) Kelley, VP of Sales, Advanced Clustering Technologies. “This advancement offered by AMD will take many of those clients to the next level not only with regards to density, but with overall cluster efficiency.”

Quad-Core AMD Opteron processors are designed to offer a seamless upgrade path for customers of Second-Generation AMD Opteron processors. They also feature AMD Virtualization™, improved floating point performance, and an energy-efficient DDR2 memory. Running existing 32-bit applications at peak performance while providing a 64-bit capable migration path is not a challenge with Quad-Core AMD Opteron processors. Energy-efficient performance on demand can reduce power consumption and upgrades within existing thermal bands are expected to offer significantly better performance.

“Through its work with AMD, Advanced Clustering has been able to leverage the industry-leading AMD64 platform to help deliver high performance, scalable solutions that work within the energy requirements for its customers,” said Patrick Patla, Director of Product Management, Server/Workstation Division, AMD (NYSE: AMD). “Built on AMD’s proven Direct Connect Architecture which directly connects processors, memory, and I/O for improved overall system performance and efficiency, Quad-Core AMD Opteron processors feature floating-point unit enhancements that can deliver up to four times the floating-point computations of previous AMD Opteron processors, making it the smarter choice to address the compute-intensive demands of HPC customers.”

Those looking to invest in a more powerful cluster can experience optimized computing power and shorter run times with projects that demand more memory bandwidth. With Quad-Core AMD Opteron processors on board, customers can get improved performance from fewer nodes and up to double the floating point power per core of their current AMD Opteron processors.
