Researches in several areas are using more and more processing information which demand more computational power to process such information. For this reason Distributed Processing is a fundamental area to make possible and supply this great demand of processing. Based on this fact, the present work proposes a methodology for processing distribution, through the Internet, using volunteer computing. The processing distribution through the Internet guarantees that processing is distributed for a great number of machines. The volunteer computing guarantees that the processing is distributed among volunteers' machines that want collaborate with a certain project. These two facts turn possible and viable system development of processing distribution in terms of cost and efficiency. The objective of the methodology is to facilitate the system development of processing distribution. The proposed methodology was used in a case study developed in this work. The objective of the case study is to implement the methodology to solve a real problem of processing demand. This selected problem is related with the relief representation through a two-dimensional polynomial. The processing demand is originated by the necessary calculations to esteem the coefficients of such a polynomial. In this case study, the methodology was shown efficient when describing all of the necessary functionalities to implement the system and robust in the moment of its execution. The proposed methodology is based in a problem class called Bag-of-Tasks. Problems of Bag-of-Tasks type can be subdivided in smaller problems and these can be solved in a distributed and independent way. The communication among the components of the system is through API of the operating system called socket.
