Correction: While Nvidia is a member of the OpenCAPI Consortium and thus doing work on OpenCAPI, at present the interface between the Nvidia Teslas and POWER9 chip is NVLink 2.0. On POWER9, both NVLink 2.0 and OpenCAPI are implemented using the same PHY. However, above that level they're completely separate protocols. (I work on OpenCAPI drivers and firmware at IBM)
