They are also capable of integrating with Power9 via OpenCAPI, which is the configuration in which many of the Volta based HPC cards by Nvidia will be used in.

- ajdlinux 9y agoCorrection: 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)
- shaklee3 9y agoThanks for the info! Can you tell me how many nvlink Lanes are used? Do you have any benchmarks showing performance of copies compared to pcie?
