Integration of NetSolve with Globus-based grids

Abstract

The paper describes the techniques for integrating NetSolve, a client-server system for solving complex scientific problems, with the Globus-based grid environments. The integration includes applying the Globus identification and authorisation techniques to the NetSolve modules and adapting the communication and computation control mechanism in NetSolve to operate in the Globus-based grids. The control communication in NetSolve is modified to use the Globus-IO. Large input and output data are transmitted through the grid FTP protocol. Computations on the remote resources are run through Globus GRAM services. The paper presents the idea and technical details of the integration. It discusses advantages and disadvantages of the modified system in comparison to the original NetSolve and provides preliminary experimental results.
