It addresses the challenge of developing a collaborative workspace with a seamless access to high-performance servers. Clayworks allows modeling of virtual clay objects and running computation-intensive deformation simulations for objects crashing into each other. To integrate heterogeneous computational resources, we adopted modern Grid middleware and provided the users with an intuitive graphical interface. We parallelized the computation of simulations using a Higher-Order Component (HOC) which abstracts over the Globus Web service resource framework (WSRF) used to interconnect our worksuite to the computation server. Clayworks is a representative of a large class of demanding systems which combine collaborative modeling with performance-critical computations, e.g., crash-tests or simulations for biological population evolution.}, language = {en} } @article{MuellerIdenDuennweberGorlatchetal., author = {M{\"u}ller-Iden, Jens and D{\"u}nnweber, Jan and Gorlatch, Sergei and Alt, Martin and Fujita, Hamido and Funyu, Yutaka}, title = {Clayworks: Toward user-oriented software for collaborative modeling}, series = {Knowledge-Based Systems}, volume = {22}, journal = {Knowledge-Based Systems}, number = {3}, publisher = {Elsevier}, address = {Oxford, UK}, doi = {10.1016/j.knosys.2008.12.001}, pages = {209 -- 215}, abstract = {We consider the development of software systems that integrate collaborative real-time modeling and distributed computing. Our main goal is user-orientation: we need a collaborative workspace for geographically dispersed users with a seamless access of every user to high-performance servers. This paper presents a particular prototype, Clayworks, that allows modeling of virtual clay objects and running computation-intensive deformation simulations for objects crashing into each other. In order to integrate heterogeneous computational resources, we adopt modern Grid middleware and provide the users with an intuitive graphical interface. Simulations are parallelized using a higher-order component (HOC) which abstracts over the web service resource framework (WSRF) used to interconnect our worksuite to the computation server.
