On a related note Mark Joshi has made his code available via the kooderive project (
http://sourceforge.net/projects/kooderive/) implementing accelerated Asian option pricing using CUDA. It seems to heavily utilize the thrust library which provides a nice C++ interface to CUDA bundled with a series of CUDA accelerated algorithms.
You could possibly, depending on the option you're wishing to price, use kooderive as a base.
Mark made a post to this list back in February indicating the possibility of integrating kooderive with Quantlib, I'm not sure of the current state of this effort.
Cheers,
James

Hi Deepak,
there are several ways to improve the performance. Before you do that i'
ll suggest you to use boost::chrono to see where the bottleneck of your
application
is.http://svn.boost.org/svn/boost/sandbox/chrono/libs/chrono/doc/html/index.html
It will measure the time you use for your application. For example.
real 0.832s, cpu 0.813s (97.7%), user 0.813s, system 0.000s
After that you can playing around by changing the container ( from
vector to list or to quantlib::array, boost::array,...)
Try to rewrite your payoff function.
If all this dont help , i 'll suggest you to port your calculation into
a graphic processor. To help you get starting see the article from
Mark S. Joshi
Graphical Asian Options
Abstract
We study the problem of pricing an Asian option using CUDA on a graphics
processing unit. We demonstrate that it is possible to get accuracy of
2E-4 in less than a fiftieth of a second.
Cheers,
Kim
