I'm surprised they used k80 and not something like 1080*. Surely they don't need the double precision-performance ? Am I missing something?

- acidtesting 10y agoCompanies like google prefer nvidia tesla data centre cards rather than the GTX 1080. Also, if I remember correctly nvidia k80 has two GPUs in one card along with 12 Gb per GPU for a total of 24 Gb. These servers have 8 nvidia K80 per system. A lot of compute power.
- tcwc 10y agoUsing a Geforce card in a datacenter or "GPU cluster" setup voids the warranty, which might be a factor for them at scale.
- kuschku 10y agoThat's invalid in the EU — maybe Google should move their GPU clusters to the EU instead.
- jamesfmilne 10y agoGTX series cards don't fit in 1U/2U/3U rack servers very well due to the design of the coolers. The Tesla cards are available in passively cooled configuration (just a big heatsink) which allows them to be cooled using the existing fans in the chassis. Facebook and Microsoft have their own 8-way GPU server designs that use a completely different connector for the GPU (SMX) instead of normal PCIe slots, again because of the motherboard/chassis design. (SMX is also used to expose the NVlink bus). https://www.nextplatform.com/2017/03/17/open-hardware-pushes-gpu-computing-envelope/ https://www.nextplatform.com/2017/03/17/open-hardware-pushes...
- happycube 10y agoThe 'rules' for data centers are kinda different (also why the DGX-1 can't be used either) - cooling is very different and having ECC is a good thing. It wouldn't surprise me if nVidia cuts favorable bulk deals on the K80, as well.
