Industry partnership set to develop cache coherent interconnect for data centres

Seven companies – AMD, ARM, Huawei, IBM, Mellanox, Qualcomm Technologies and Xilinx – have united to develop the Cache Coherent Interconnect for Accelerators (CCIX), a single interconnect technology specification that, the partners say, will enable processors using different instruction set architectures to share data coherently.

Accelerating data centre applications has become important as operators look to reduce power consumption and system size. A number of applications, including big data in memory database processing, video analytics and network processing, are said to benefit from acceleration engines that need to move data seamlessly among the various system components. CCIX, say the partners, will allow these components to access and process data, irrespective of where it resides and without the need for complex programming environments.

“A ‘one size fits all architecture’ approach to data centre workloads does not deliver the required performance and efficiency,” said Lakshmi Mandyam, director server systems and ecosystems with ARM. “CCIX enables more optimised solutions by simplifying software development and deployment of applications that benefit from specialised processing and hardware offload, delivering higher performance and value to data center customers.”

“CCIX will leverage existing server interconnect infrastructure and deliver higher bandwidth, lower latency and cache coherent access to shared memory,” claimed Gaurav Singh, Xilinx’ VP of architecture. “This will result in a significant improvement in the usability of accelerators and overall performance and efficiency of data centre platforms.”
