Abstract: The optimal resource allocation satisfies the needed capacity of the used resources. To such analysis we can use both analytical and simulation methods. Principally analytical methods (AM) belong to the preferred method in comparison to the simulation method, because of their potential ability of more general analysis and also of ability to analyze massive parallel computers. This article goes further in developing AM based on queuing theory results in relation to our published paper in [9]. The extensions are in extending derived AM to whole range of parallel computers and also to sum up public acceptance of our published paper. The article therefore describes deriving of correction factor of standard AM based on M/M/m and M/M/1queuing theory systems. In detail the paper describes derivation of a correction factor for standard AM to study more precise their performance. The paper contributions are in unified AM and in deriving correction factor in order to take into account real non-exponential nature of the inputs to the computing nodes and node’s communication channels. The derived analytical results were compared with performed simulation results in order to estimate the magnitude of improvement. Likewise the corrected AM were tested under various ranges of parameters, which influence the architecture of the parallel computers and its communication networks too. These results are very important in practical use.

Abstract: Online social networks (forum) have become extremely popular; numerous sites allow users to interact and share content using social links observing that there are some limitations on most of the social interaction networks. A recent study has demonstrated that the “strength of ties” varies widely, ranging from pairs of users who are best friends to pairs of users who even wished they weren’t friends. In order to distinguish between these strong and weak links, researchers have suggested examining the activity networks, the network that is formed by users who actually interact using one or many of the methods provided by the social networking site. Also for effective study, we collect data on both friendship relationship and interactions for a large subset of the Facebook social network and forum, Twitter, 2go, m.eskimi and other social interactive networks. From a technological standpoint, forums or boards are web applications managing user-generated content. Early Internet forums could be described as a web version of an electronic mailing list or newsgroup (such as exist on Usenet); allowing people to post messages and comment on other messages. It has been discovered that Chat forum is one of the newest way in which organization and the business world use now to reach out to their numerous customers in order to get feedback and responses concerning its entire product lines to share of their opinion.
