Grid portals are one of the most popular user interfaces to Grids. Grid portals build upon the familiar Web portal model offer to virtual communities of users a single access point to computational or data resources. P-GRADE is a Grid portal solution that allows users to manage the whole life-cycle for executing a parallel application in the Grid. The purpose of this article is to introduce the structure of a Grid-aware portlet for linear algebra calculations based on the P-GRADE portal. To accomplish this goal, the portlet provides the seamless bridge between the linear algebra calculations and various linear algebra software environments (middlewares, tools, parallel programming techniques, linear algebra libraries) deployed over a grid. The portlet GUI (Graphical User Interface) is lightweight and uses standard web technologies. Moreover, since today smartphone are ubiquitous, we propose to provide an easy and adapted way to monitor the portlet's operation from a mobile device and illustrate its practical use.
