SETI@HOME

Introduction

In this paper we are going to use the SETI@HOME technology for the analysis of the result of drug tests for our organization. The organization is responsible for undertaking a large number. Public service projects, which are the reason why we have decided to use the Distributed system technology of SETI@HOME, as there is a large number of data which the organization will be collecting and analyzing. SETI stands for Search for Extraterrestrial Intelligence; this project is also referred to as the search for intelligence alien. SETI@HOME is a project of University of California; the project began in the 1984. SETI@HOME is probably the first distributed computing project that has been widely distributed with about five million registrants in its first version. SETI @ Home performs a series of FFT on the data it is given to analyzing (extracting the frequency component of a signal). If the signal is random in nature, we will not witness the "peak" on a given channel. If a peak is observed: it gets interesting it may be an extraterrestrial transmission. To be sure SETI @ Home checks if the spectrum is slightly spread to other frequencies (due to rotation of the Earth). In addition, the Arecibo telescope is fixed by the rotation of the Earth, the signal will be picked up on one side of the antenna, will pass through its center and then depart to the other side to avoid being captured. The peak amplitude of a possible extraterrestrial signal, therefore, its amplitude will increase and then decrease over time bell-shaped easily modeled (Bowyer et al, 1996, pp. 667-669.).

SETI @ HOME is a project of distributed computing platform running on the computer Berkeley Open Infrastructure for Network Computing (BOINC) developed by the Space Sciences Laboratory at the University of California at Berkeley in the United States of America. Its purpose is to analyze radio signals, looking for signs of extraterrestrial intelligence, and is one of many activities undertaken as part of SETI.

Discussion

Distributed processing

Distributed processing is defined as the way it is possible to connect different machines, PC's for example, in certain types of communication network, usually a LAN or a network or a wide area network like the Internet. Thus achieving a single data processing task can be processed or executed across multiple machines on the network, meaning that a single process can be made ??from several different machines connected to a network. A common mistake is confused and parallel distributed processing, the term parallel processing, basically is the same, except that different machines tend to be physically very close in parallel system, which is not necessary in a distributed(CHAMBERS, 1984, pp.34-67).

In the project SETI@HOME distributed computing has been developed through server software that divides data into chunks of the radio telescope, distributes those pieces to customers and collects the results. Each piece will possibly consist 250K. It also manages the distribution of versions for specific architectures and analysis code is in charge of several security issues (VAKOCH, ...
