Just as an update to my setup and results-
Broker - now a 1U server with 12GB RAM (getting more soon)
Node 1 - 7990, 6970
Node 2 - 7990, 6970
Network - still dedicated Gb switch
Software- oclhashcat-plus 0.15, VCL 1.22
Guess the setup didn't like having 2 7990s in one box, because this way I'm getting much better results. Individually, the boxes hit ~10 000K/sec in md5crypt, and now, in VCL, I'm getting ~12 000K/sec total out of the six GPUs; still a lot of loss, but at least the sum is greater than the parts!
Gonna try and test with some Infiniband hardware next, and hopefully get a normal, fully running cluster.
