In recent years much research has gone in grid computing and building shared resource networks. The grid computing has given access to the research community to high computational resources. The pricing of grid resources has been evolved along with resource management however there is a need for a better pricing model which is well suited for services. In this paper, we first explain the notion of...
In addition to multi-national Grid infrastructures, several countries operate their own national Grid infrastructures to support science and industry within national borders. These infrastructures have the benefit of better satisfying the needs of local, regional and national user communities. Although Switzerland has strong research groups in several fields of distributed computing, only recently...
This paper describes the parallelization (gridification) of the phylogenetic package PHYLIP on a large scale distributed system termed XtremWeb- CH. PHYLIP is a package of programs for inferring phylogenies (evolutionary trees). It is the most widely- distributed phylogeny package. PHYLIP has been used to build the largest number of published trees. It's known that some modules of PHYLIP are CPU time...
This paper describes a global computing (GC) environment, called XtremWeb-CH (XWCH). XWCH is an improved version of a GC tool called XtremWeb (XW). XWCH tries to enrich XW in order to match P2P concepts: distributed scheduling, distributed communication, development of symmetrical models. Two versions of XWCH were developed. The first, called XWCH-sMs, manages inter-task communications in a centralized...
