Re: [Quantlib-users] Help in running QuantLib in multithreaded process on windows

[Ashish K. <ash...@3i...>]

You will have to make the Singleton class template thread-safe. The 
simplest way is to put the data in Thread-Local Storage. Using a mutex 
is not really ideal, as you'll run into performance issues very quickly.

Also, check that you are not writing to shared STL containers in 
multiple threads, as the STL itself is not guarenteed to be thread-safe.
