Question

Now that the current generation of desktops are 64-bit machines with multiple 'cores', how do I write programs that take advantage of all that power?

Answer 1

it means you can use other language than C because C is made to be very optimised :D

Answer 2

Typically, you use either threads or multiple processes. Ideally, you use a higher abstraction than either, like actors, that is scheduled concurrently in threads for you by some third-party library.

Answer 3

We're still exploring this frontier, so it's still pretty nasty stuff to deal with :)

Answer 4

Welcome to the new paradigm! MPP ( Massively Parallel Processing ) is just starting. Programming will probably end up being more about coordinating, and checking state between what's going on in all the cores than the algorithms.

So much for what hair I still have.
