I know that my question is a pretty basic one. But nonetheless I wasn't able do answer this question by myself or the tutorials:
Question: what are the minimum hardware requirements for a Workstation which will be extended with a Xeon Phi coprocessor? Does it work with any Mainboard having an PCIe x16-Slot and sufficient power supply or are only a small number of especially certified Systems allowed to work with this coprocessor?
Thanks in advance for helping me out,
kind regards, Jakob
I am in the process of building a workstation for dual Xeon Phi. The motherboard I chose (ASUS P9X79WS) states it has BIOS that supports Intel Xeon Phi (and nVidia Tesla). The question I have is PCIe 3.0/2.0 x16 slot requirements. Can the Xeon Phi operate in slot of PCIe 3.0/2.0 x16 in mode x8 (though at slower transfer speed)? The motherboard can have two cards at x16 mode, and the initial setup will place the (low end) video card in a PCIe 3.0/2.0 x16 mode x4 slot.
Second question is if the Xeon Phi will operate in x8 mode, what is the expected impact (please answer from experience, not speculation).
To answer my own question, in reading Intel® Xeon Phi™ Coprocessor System Software Developers Guide Page 12:
Both x8 and x16 configurations are supported.
