2 How to Sustain the Application Performance Growth Curve? Performance gains from technology advances are diminishing Complexity of the SW deployment stack is increasing Execution layers can no longer be optimized in isolation Need a new methodology for application performance delivery: Tune entire application deployment stack on-site and ondemand Vertical integration Application App Server JVM O/S Hypervisor Hardware Application deployment stack Continuous and adaptive 2 PERCS Continuous Program Optimization September 16, 2004
3 Continuous Program Optimization (CPO) through Performance & Environment Monitoring () Continuous Program Optimization (CPO) increases programmer productivity by automating the laborious and challenging performance tuning effort CPO aims at tuning application by optimally adapting the application to its behavior and environment adapting environment resources to application behavior CPO is made possible through continuous whole-system Performance and Environment Monitoring () Tune & adapt (CPO) Monitor & evaluate () Continuous optimization loop 3 PERCS Continuous Program Optimization September 16, 2004
4 A Catalogue of CPO Scenarios Adapting applications to execution behavior and environment Library Tuning Adaptive MPI tuning Tuning Just-In-Time (JIT) compiler heuristics Interactive tuning environment to support algorithmic tuning Adapting the execution environment to the application s needs: Tuning the Virtual Machine (heap size, GC policies) Tuning the operating environment/os (adaptive page size, adaptive file cache management (FCM)) 4 PERCS Continuous Program Optimization September 16, 2004
5 CPO Architecture 2 Components to implement CPO scenarios: : Vertical Performance and Environment Monitoring Implements programmable monitoring functionality across execution layers Provides integrated whole system view CPO Agent (Specific to CPO scenario) programs to provide desired monitoring information Implements specific scenario optimization There may be several CPO Agents active in the system, interconnected through Application App Server Operating System Hardware Java VM Hypervisor CPO Agent control performance knob negotiate knob 5 PERCS Continuous Program Optimization September 16, 2004
6 Performance & Environment Monitoring () Flexible monitoring infrastructure to integrate monitors across execution layers Platform-independent API (API) to program CPO Agents CPO Agent for offline event tracing and logging CPO Agent for implementing CPO scenarios Designed to serve as integral part of CPO as well as stand-alone tool set Application App Server Java VM Operating System CPO Agent Event Trace Trace Visualizer Hypervisor Hardware 6 PERCS Continuous Program Optimization September 16, 2004
7 Infrastructure 1) Language-independent specification of events and their semantics 1 2 XML Event specification Tools 2) Generate language-specific event data structures and header files (Java, C, C++, Fortran) to support Layer instrumentation library CPO agent 3) implementation with a platformindependent API Application Virtual Machine O/S CPO Agent Hardware/Simulator Library 3 trace PE2 Visualizer 7 PERCS Continuous Program Optimization September 16, 2004
