[Users] Compatibility between different OFED versions (1.5 vs 3.5)

[Fedele Stabile]

Hello,

I want to know if someone has experimented problems in building an
etherogeneus cluster that consists of 

-            A-nodes with Infiniband Mellanox ConnectX card, OFED 1.5.4
software

-            B-nodes with Infiniband Intel card, OFED 3.5.2 software

-            switch Voltaire

each node in their own group (A-node or B-node) speaks with the other in
their group BUT nodes in the A group don't speak with nodes in the B group
and vice-versa.

 

Can you help me?

Thank you in advance,

Fedele Stabile
