Dual- and quad-core processors are becoming more and more common and offer a reasonable increase in calculation performance when calculating large noise maps. Up-to-date high-performance workstations either come with two dual-core 64-bit-processors (providing 4 CPUs) or even two quad-core 64-bit processors (providing 8 CPUs). These multi-core processors enable to calculate 8 parallel CadnaA-batch-processes in parallel. In comparison, this would have required 8 single PCs in the past. Imagine: You require just a single CadnaA-licence for a multi-core PC able to handle up to 8 processes in parallel! Furthermore, the hardware costs are reasonably lower compared with 8 individual PCs!

It is required that the software supports the so-called multithreading. CadnaA supports multithreading in a comfortable way. On the dialog "Multithreading" you can decide alternatively to use a single, all available, or a distinct selection of processors to be used for a calculation job. For a PC with two quad-core CPUs eight processes are displayed on the Windows-Task-Manager, all running at 100% CPU-capacity.

By the way: CadnaA is already designed to handle up to 32 parallel processors today and thus is prepared to compete with future hardware developments.
