I have no experience with that switch, but have a few comments...
For gigabit NICs for linux, we have had good experience with the
NetGear GA620 cards (not the GA622s which are a different chipset).
They are well supported by the acenic driver and function well for us.
As for channel bonding, I really don't think you'll need it for
genetic programming and neural networks as those aren't traditionally
very-high-bandwidth applications if I am thinking about them correctly.
(That is if by genetic programming you mean genetic algorithms and not
Not to mention the added complexity and time needed to implemenet channel
bonding, I just don't think it would be worth it in this case.
It seems to me that many cluster workloads work fine with just fast
ethernet to the nodes.
