Various so-called Grid Widgets, which have been developed by the Grid development team here in National Center for High-performance Computing (NCHC). These widgets were set out to provide users with seamless and scalable access to Grid resources. Currently, it joins the Grid, WebOS, and automatic resource selection mechanism to build a virtual computer in distributed environment. This progress helps to lower the barrier for using Grid Computing Environment. It provides extremely lightweight approach to acquiring Grid services and flexible Grid Widgets for user to use the geographically distributed heterogeneous Grid resources. On the scheduling scenario, the developed Resource Broker along with its capability to automatically allocate resources with the feature of dynamic load prediction has improved the performance of the dynamic scheduling over conventional scheduling policies. The Grid Widgets provided can also be customized and configured freely to suit the needs of the end users.
