OS X 10.6 : Grand Central Dispatch

For the longest time multicore macs have unfortunately been held back by old and un-optimized code that was designed for single core CPUs. If you have any sort of system monitoring device on your computer you may notice that your mac is often using 100% of one core and 0% of the other. The release of Snow Leopard and the inclusion of GCD (Grand Central Dispatch) hopes to change all of that.
More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central Dispatch takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central Dispatch also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.
