Bill,

Thanks for the code.  Any chance that you have a quadratic
optimization method defined in Erlang code?  I'd be very curious to

Cheers,
Whit

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.
