Intel having little presence in HPC is a laughable claim. There are plenty of Intel Xeons on the TOP 500 https://www.top500.org/list/2017/06/ https://www.top50

Intel having little presence in HPC is a laughable claim.
There are plenty of Intel Xeons on the TOP 500 https://www.top500.org/list/2017/06/ https://www.top500.org/list/2017/06/ and these Nvidia GPUs don't run themselves.
- modeless 9y ago> these Nvidia GPUs don't run themselves It's only a matter of time before they do. Nvidia's Drive PX platform is Intel-free and something derived from it might look interesting for HPC and/or high-end workstations in the next few years.
- whoisjuan 9y agoSerious question. How likely is for Nvidia to become relevant in the CPU space in the next 10-15 years? (talking specifically about their attempts in this market with things like Tegra)... OR is their goal to keep optimizing form factor, thermal efficiency, energy consumption, etc...to the point they can make a case for a stand-alone GPU effectively replacing a CPU?
- orbifold 9y agoThey've already build their own ARM cpu's, they are in the TX1, Nintendo Shield for example. Their most recent Volta GPU made significant progress in terms of general purpose programmability, it gained a much more flexible memory and concurrency model compared to previous chip generations. They also partner with IBM by supporting OpenCAPI for HPC.

- mywittyname 9y agoI've long felt that nVidia is going to rise from the ashes of Intel, not AMD.
- orbifold 9y agoThey 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?
