GridGain looks *perfect* for JBT, sadly, I don't have so many machines at my disposal. Just my 2.53 GHz MacBookPro and my PC (also running on another 2.16 GHz MacBookPro). I suspect I could get it to work across the two, but I don't think it'd be worth it. After all, it'd be easier to split the range of one of the parameters in half and run each half on different machines.
I was playing around with machines at GoGrid today, their fastest machine was disappointing and with its 6 cores @ 3GHz each and 8 GBs ram, was only a little bit faster than my 2x 2.5 GHz and 4GB MacBookPro. And, considering I've already paid for my Mac, it seemed a bit silly to pay $1.50 an hour for the GoGrid machine. Having said that, it was wicked easy to get going with them. I think the real gains will come from spawning about 16 cloud machines and putting them into a single grid with GridGain (or similar).
