Improving SegHidro/BRAMS with EELA: Enhancing User Experience Through Integration

This presentation highlights the successful gridifying of meteorological applications on SegHidro Portal, including modules for data uploading, validation, job submitting, monitoring, and output retrieval. It also covers the integration of gLite middleware components, architecture optimizations, and integration with OurGrid. Future steps include setting up an EELA site at LSD and enhancing system availability and performance.
