In computer science, a parallel algorithm, as opposed to a traditional serial algorithm, is one which can be executed a piece at a time in many different processing devices, and then put back together again at the end to get the correct result.

Some algorithms are easy to divide up into pieces like this. For example, splitting up the job of checking all of the numbers from one to a hundred to see if it is divisible by seven could be done by assigning a subset of the numbers to each available processor, and then putting the list of positive results back together. Most of the available algorithms to compute Pi, on the other hand, could not be easily split up into parallel portions. Most of them require the results from a preceding step to effectively carry on with the next step. Lowercase pi The mathematical constant Ï€ is a real number which may be defined as the ratio of a circles circumference (Greek Ï€ÎµÏÎ¹Ï†ÎÏÎµÎ¹Î±, periphery) to its diameter in Euclidean geometry, and which is in common use in mathematics, physics, and engineering. ...
Parallel algorithms are valuable because it is faster to perform large computing tasks via a parallel algorithm than it is via a serial (nonparallel) algorithm, because of the way modern processors work. It is far more difficult to construct a computer with a single fast processor than one with many slow processors with the same throughput. There are also certain theoretical limits to the potential speed of serial processors. In information technology, throughput is the rate at which a computer or network sends or receives data. ...
A subtype of parallel algorithms, distributed algorithms are algorithms designed to work in cluster computing and distributed computing environments, where additional concerns beyond the scope of "classical" parallel algorithms need to be addressed. In computer science, a distributed algorithm is an algorithm that executes on more than one machine or processor. ...
