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

Hi,
who of you in this forum uses R (http://www.r-project.org/) with the
multicore, SNOW or CUDA packages, so for advanced calculations that need
more power than a workstation CPU? On which hardware do you compute these
scripts? At home/ at work or do you have data center access somewhere?
The background of these questions is the following: I am currently writing
my M.Sc. thesis about R and High-Performance-Computing and need a strong
knowledge about who actually uses R. I read that R had 1 million users in
2008, bu thats more or less the only user statistics I could find on this
topic - so I hope for your answers!
Sincerely Heinrich
