IMHO the standard libraries are rather perverse when used for programs to be run on multi-processor machines - which many people own today. Naive use of the STL containers, in particular, causes a multithreaded program to run slower on multi-processor machines.
Have you tried plugging the HOARD memory allocator into your program?
I would like to see BOOST begin to address this issue, hence my post.
Multicore aware programming is more than a simple issue, and certainly not solved just by an efficient allocator (although this doesn't hurt ;) ). There is a task library under development that should help a bit regarding efficient multi-threaded programming. I don't know what it's current status is. When you have an efficient task scheduler, writing parallel version of STL algorithms is easier. Last but not least, you have Boost.STM: http://eces.colorado.edu/~gottschl/dracoSTM/index.html -- EA
