Thanks Benson, these are very useful links. I browsed the Mellanox  
guide and it seems the target audience is experts in networking. I  
wish there was some quick start guide or Infiniband for dummies book :-)

> Maybe also helpful (students who have participated in cluster

> tests on your hardware.
