The same question comes for GPUs.
I can't speak for GPUs, but I think the PCI information will be useful to know what devices are close to what PUs / NUMA nodes. That information can be used to make decisions about binding, for example (i.e., you want to be "close" to the specific PCI resources that you'll be using). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
