R doesnot have a 1 million or two million users (thats an Urban legend
thanks to Vance NYT article)

. The exact number is not proven and estimated by a variety of
association  by proxy methods. It could be as low as 5,00,000 or as
many as 5 million users. It's like speculating which private equity
companies is Goodnight investing in. A better estimate would be
counting the number of downloads of R 2.12 or analytical log analysis
of various CRAN websites.

You can read my 2 cents on using SNOW, DOSNOW, FOREACH on Multi
Processor Amazon Instance Here- it is not quite theory but more like a
step by step screenshot tutorial- insert your own algol in it to see
the ramp up speed. It is an elaboration of the Grossman original
opendata post and mashes a bit of code for Tal G (replacing Revo's
package for making the connection)


or if you like to use Revo's packages or find it difficult to go just
commado line -

 run Ec2 on Windows (and I havent managed the Ubuntu port yet- though
EC2 does have REL instances.


An additional point is Amazon Micro instances are free for a year- for
linux but limited to 600~ mb RAM and you probably need to use the
small (>2 processor instance) to sandbox
