I presented a keynote for Sun at Supercomputing 2003 in Phoenix Arizona and included the slide shown below. CXL is a memory protocol, as shown in the third block in my diagram from 2003, and provides cache coherent latency around 200ns, and up to 2 meters maximum distance. This topic needs further research and additional blog posts!
