[erlang-questions] Article on Erlang in ACM Queue

I think it depends on how much you can do in parallel and how much is really floating point as contrasted to function calls and the like.  I wrote a numerical integration routine with a parameter N for the number of cores I expected to use.  Even with N = 2 it was better than some competing sequential versions.  I'll attach the code.

Subject: Re: [erlang-questions] Article on Erlang in ACM Queue

I'm new to Erlang. I've been considering it for a few simulation
projects in finance.  However, I was discouraged because the ACM
article suggests that Erlang has poor floating point performance.

Are any list members using Erlang for numerical simulations?  If so,
do you have any advice on how to how to improve efficiency?  What
about using binaries to store vectors of doubles?  Are there any
extensions of Erlang that allow one to do that?

Any feedback is appreciated.

Thanks,
Whit
