Parallel computing is a form of computation in which many calculations are carried out simultaneously, operating on the principle that large problems can often be divided into smaller ones, which are then solved concurrently ("in parallel").

There are few large scale, high performance, parallel processing compute servers available here, which are designed for speed, scalability, flexibility, manageability and availability.

Parallel computer programs are more difficult to write than sequential ones, because concurrency introduces several new classes of potential software bugs, of which race conditions are the most common. Communication and synchronization between the different sub-tasks are typically some of the greatest obstacles to getting good parallel program performance.
