Subject: AMBER: gigabit ethernet cards and switches

HI everyone

We are considering to buy a new 'low-cost' computer cluster dedicated
to MD simulations. We already have two clusters interconnected by
gigabit ethernet. One of these is composed by intel quad-core
processors and, as discussed many times in this list, suffers from
scaling problems when running Amber in more than two nodes.

That said, I would like to ask to users and developers about good
choices to be considered when buying gigabit Ethernet cards and
switches. My dream is to convince my PI to upgrade myrinet, but price
is also an important issue.

By the way, the cluster will probably be composed of intel quad-core
processors as well.

All suggestions are welcome,

Thanks in advance
