Hello, Martin.
AFIK, the 'cloud' is based on warehouses full of COTS servers, not on
top500 HPC clusters. You're NOT going to get 'BlueGene' performance at
knock-down prices. You get what you pay for.

Iff you are only going to run your jobs once in a while, and Stewart has
kindly set up a virtual image of Bio-Linux with everything you want to
use already preconfigured, and all the databases you want to access
transparently shared between all the anonymous 'cloud' nodes you get for
8 dollars and hour, then you are in business.

The 'cloud' itself is a proprietary system. It's the opposite of HPC
clustering. What is the point of using virtualised Bio-Linux instances
just to 'cluster' them? If I want to use a top500 class computer, I'll
join the queue on a real one. However, I follow Donald Becker's example,
and use my own DIY Bio-Linux Beowulf cluster instead :-)
Bye,
Tony.
