Re: Debian-Med images for Amazon Compute Cloud?!?
Yes, it works great for science calculations. I used about 15
machines or so to make a big quartet tree a while ago and it worked
great. [1] The two main problems I remember with Amazon EC2 were the
potentially changing dynamic IP address assignments and the chance
that you can lose all data if you terminate your instance. But I
think both of these are mitigated now. Such as with S3 as a storage
backend. Cheers,
Rudi
