IBM BladeCenter QS22


	Overview \| Features & benefits \| Specifications \|

Highlights

Third generation blade system based on an enhanced version of the Cell Broadband Engine™ (Cell/B.E.) Architecture
IBM PowerXCell 8i processor, offering five times the double precision performance of the previous Cell/B.E. processor
High-performance blade solution for selected workloads
Significant performance acceleration of target workloads such as rendering and medical imaging
Up to 32 GB of processor memory.

The IBM BladeCenter QS22 is based on the innovative multi-core IBM PowerXCell 8i processor, a new generation processor based on the Cell/B.E. Architecture. Offering extraordinary double precision floating point processing power, the QS22 can yield application results faster and with more accuracy. This can enable organisations to get information faster to facilitate important business decisions.

For many years, organisations have relied on performance gains from increasing clock speeds of ‘traditional’ microprocessor architectures. However, in recent years this approach has been challenged by the physical limitations of semiconductors and by traditional processor architecture implementations. Issues with power consumption, heat dissipation and memory latencies have led to diminishing returns on performance. High performance computing (HPC) applications such as digital content creation, electronic design automation, image and signal processing, financial algorithms, scientific research and seismic processing may need a fundamentally new technology and approach to the system-level architecture to achieve the desired level of performance.
