Researchers Develop New Chip With Intel To Boost Multi-Core Communication
A research team, in collaboration with Intel, from North Carolina State University have managed to boost the communication speed between different cores of a processor. Seeing how pretty much every computer and mobile device these days relies on multi-core processors, this advancement will go a long way in improving speeds for various tasks.
The current method of communication between cores utilizes software commands to send and receive data. Although the method gets the job done, it is a slow process since it requires the core to read and execute the software which ultimately ends up decreasing the overall performance of the processor.
Working alongside Intel, the researchers at the university built their own custom chip that completely removes the software part involved in core communication. In its place, the new chip adopts an integrated hardware based solution to speed up communication between multiple cores.
A small device called queue management device, QMD, is attached to the processor in this case. The QMD keeps track of all communication requests between cores inside the processor and is capable of simple computational functions which ends up giving the core a boost of up to 15 percent when performing such computational tasks.
According to Yan Solihin, a professor of electrical and computer engineering at the university and one of the researchers who worked on this new chip, this method of communication, core-to-core communication acceleration framework, improves performance by two to 12 times compared to traditional core communication. This means that execution time of processes is at least twice as fast than before.
Solihin also said his team is currently looking to develop other on-chip devices that could accelerate additional multi-core computations. Their work will be presented in a paper titled, “CAF: Core to Core Communication Acceleration Framework” at the 25th Annual Conference on Parallel Architectures and Compilation Techniques in Israel on 11th September.
