Day 1 Keynote: IBM OpenPOWER Roadmap
summary
Roadmap focuses on coherent hardware acceleration and a redesigned memory subsystem that moves the memory controller onto the DIMM (a differential DIMM or D-10) so different memory technologies plug in without CPU or motherboard changes, enabling DDR4 today and DDR5 later; openCAPI evolves to openCAPI 4.0 to allow attached devices to cache system memory coherently; a 40 nm CMOS variant of the Power9 family adds more accelerator and memory capability while addressing the pain of 1,800 pins for eight DDR4 channels under a common OMI open memory interface.
