How can we know whether Intel Xeon Phi coprocessor is present or not

Question

I want to run a program on Intel Xeon Phi coprocessor. How can I know whether my machine has an Intel Xeon Phi coprocessor or not.

Answer 1

Well if it has one you should probably know as it is large (see pictures here), costly (several times the price of a desktop), and it generates a lot of heat (you need special fans) and drains a lot of electrical power (you need a special PSU).

otherwise lspci | grep Co-processor will tell you whether you have one or not.

Answer 2

if you have a MIC (Xeon Phi) card attached to your machine then you would be able to ssh to it by ssh mic0 command. This will only work if you installed MPSS though.
