[Beowulf] many cores and ib

Hello,

Just a small question, does anybody has experience with many core
(16) nodes and infiniband? Since we have some users that need
shared memory but also we want to build a normal cluster for
mpi apps, we think that this could be a solution. Let's say about
8 machines (96 processors)  pus infiniband. Does it sound correct?
I'm aware of the bottleneck that means having one ib interface for 
the mpi cores, is there any possibility of bonding?

Thanks a lot and regards
