IPoIB in Xeon Phi

[Alfonso_P_]

Hello,

I am configurating Lustre in Xeon Phi. But only works with mic0 (mic0-br0-eth0) interface. It's possible to configure intel xeon phi scif0 interface with IPoIB and connect lustre inside Xeon Phi by Infiniband (o2ib).

Regards

Thanks in advance!

No. Xeon Phi's IPOIB is built on top of "MIC Kernel CCL Direct" drivers. It'll not work on scif interface directly. Any reason you want to run on scif0 ?

I think I misunderstood you .. what you want is to run Lustre on top of Infiniband ? The set of kernel drivers are offered in MPSS 3.x as an experimental feature. You would need

• Install MPSS 3.x
• Get the corresponding luster rpms that support Xeon Phi
• Configure OFED-3.5.1-mic (see the Admin Guide)
• Configure ib0 interface (see the Admin Guide)

Then the rest should be identical to the usual Lustre setup. Again, it should be on ib0, not scif0.
