About data transferring on the data ring bus

[Jie_Y_1]

Hi all, 

I have a question about the ring bus. 

I hope if someone could tell me some specifics about how data are transferred and managed(protocol) on the BL ring please?

Appreciate your help. Thank you.

Hi Jie,

Have you looked at the document "Intel® Xeon Phi™ Coprocessor System Software Developers Guide" (https://software.intel.com/en-us/articles/intel-xeon-phi-coprocessor-system-software-developers-guide) yet? this document contains some information related to your question.

Hi Loc,

Thank you I have checked the system software developers guide but some mechanisms are still unclear for me to understand. For example whether data is transferred by packets or not, if so, how is the header looks like... Unfortunately didn't find any specific description is revealed in any documents.
