Xingfu Wu Snapshot of Performance Monitoring

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

Xingfu Wu 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
