infiniband setup guide?

Hi,
Can anyone point me to the working infiniband setup guide for using vclhashcat?
I've tried several guide that found in google, found this one is quite easy:
http://pkg-ofed.alioth.debian.org/howto/...wto-4.html

And then 2 machines can ping each other, but when running vclhashcat, it only detect 3 cards in local computer, then kernel, and just frozen there
eg:
Device #1: Cayman, 1024MB, 800Mhz, 24MCU
Device #3: Cayman, 1024MB, 800Mhz, 24MCU
Device #3: Cayman, 1024MB, 800Mhz, 24MCU
Device #1: Kernel ./kernels/4098/m0000_a1.Cayman_938.2_CAL 1.4.1741.kernel (490316 bytes)

then it does nothing.

Help please
Will reward if required.
