It'll be interesting to see how CXL shakes out. It might end up being not much more than cross socket access! 150ns to go between sockets is about what we see here & is in the realm of what CXL had been promising.
Having a super short lightweight protocol like CXL.mem to talk over such fast fabric has so much killer potential.
These graphs are always such a delight to see. It's a network map, of how well connected cores are, and they reveal so many particular advantages and diaadvantages of the greater systems architecture.
- loxias 3y agoI, too, am excited for CXL. Not enough people got to _feel_ the awesome of pmem. I think if more people had, pmem would be in all our laptops, desktops, servers.
