Concluding Discussion

TAU portal has been developed to support the FLASH regression testing

Allows members of FLASH group to share profiling data in a secure way

Allows users to launch TAU performance tools (paraprof, perfexplorer)

Nightly regression testcases uploaded to the database automatically
