  4. Three Components of Volatile • Volvis: main program • Rendering • Scalable displaying • User interaction • Optistore: data server • Assist visualization dataset handling such as data management, processing, representation and transport • Filter raw volumetric data and produce visual objects • Transfer Function Editor (tfUI) • User interface for transfer function selection Xingfu Wu <wuxf@cs.tamu.edu>

  11. Snapshot of Performance Monitoring Xingfu Wu <wuxf@cs.tamu.edu>

  12. Short-term Plans • Port the instrumented Volatile to a large-scale optiputer testbed for analysis (3/2005) • Analyze the performance of JuxtaView and LambdaRam applications (6/2005) • Where possible, develop models of data accesses for the different visualization applications (9/2005) • Continue collaborating with Jason’s group about viz applications (12/2005) Xingfu Wu <wuxf@cs.tamu.edu>

  13. Long-term Plans Year 3: • Continue with analyzing Volatile on large-scale OptIPuter testbed • Work with Jason and Luc on redesigning Volatile • Start working on JuxtaView and LambdaRam Year 4: • Work with new Volatile, LambdaRam, JuxtaView on large-scale OptIPuter testbed • Where possible, develop models of data accesses for different viz applications Year 5: • Continue collaborating with Jason’s group about viz applications • Integrate performance monitoring with software stack to aid in making performance directed decisions Xingfu Wu <wuxf@cs.tamu.edu>
