Intel Xeon Phi Coprocessor with eGPU over Thunderbolt 3



I did some testing with my akitio to connect my intel xeon phi 7210A to my chuwi box pro as I saw it had a thunderbolt port.
The result is conclusive and I can communicate with the card and test some code.
I installed mpss 3.8.6 under windows 10 home and tested the following programs:
-micinfo OK/KO because it can't read the pci bus
-micckeck OK
-micctrl OK
-micflash OK
-micsmc and micsmc-gui can't detect the card (I think you have to change the code that uses mic_pci_config)

I can connect to the card via putty and run compiler programs from the host (command line or via visual studio and intel compilers)

The mini pc chuwi box pro (UEFI) does not show an option from the bios to enable "4G decoding above" mode but it should take the activation of I/O in 64 bits memory.

I show you some pictures below of my manipulations and tests of some programs that are in the mpss sdk:




I will do a test with the xeon phi 7220A and mpss 4.4.1 afterwards.

I had also tested more than a year ago the same thing on a macbook air + thunderbolt port under ubuntu and I had to adapt the programs mpss,libscif etc... and the card was recognized and I was able to see the information of the card.
Can you see my work from git (for information I am not a 100% c/c++ dev):
