I'll make a bit of a wild guess here: From reading previous posts, IB
support in LAM is not very complete. I'm sure there are some fairly good
reasons for this; I suspect one of them is the state of the IB drivers is
not particularly stable (meaning they are rapidly changing, and hitting
the moving target is difficult).
Then there's OpenMPI, which I believe is the intended sucessor to LAM...
I'm fairly confident that it's possible to implement Checkpoint/Restart in
IB; it just hasn't been done yet.
