Most of the described tasks performed on a single processor, in the Windows environment. Traditionally, these tasks were performed on supercomputers and clusters of computers in the UNIX environment. However, modern programs and processors have reached efficiency allows to do many types of calculations on a personal computer. Only a large task, such as lipid bilayers simulations, requires usage of the powerful machines.
In recent years, processing power has grown very slowly however the new Intel processors (Sandy Bridge ) are very suitable for the molecular mechanics. According to our tests, they work in 2-2.5 times faster.
