It looks like the climate change integration plug fest is set to take off. The hardware has arrived in boxed form; and should be online shortly. To take part join the ccip mailing list where they will sort out login credentials etc.
The size/power of these machines is a bit of a shock to me. I am not used to the wild world of virtualization and was expecting a series of dedicated machines in order to emphasis performance. It will be very interesting for me to see how well virtualization copes with the kind of load produced the different GIS stacks; and conversely if we can make a dent in this amount of processing power.
