[LINK] Intel guide for multithreaded apps

[Frank O'Connor]

Mmmm,

The problem at the moment is that multi-core and 
hyper-threaded technology is way beyond the 
current development tools, compilers, IDE's and 
techniques used in the development community.

Software again trails hardware capabilities by a long margin.

That's slowly changing, but I've yet to see any 
commercial software that make optimal use of the 
hardware that's currently out there.
