|
| What information should a performance tool gather from each level in your software stack? What performance information should each level of your software stack maintain for inspection by performance tools? How would a tool get this information: register a signal handler, call an async-signal safe function from a signal handler, register a callback, call a function from a registered callback, or something else?

| What types of performance problems do you want tools to measure and diagnose? Resource consumption/utilization? Waste? Inefficiency? Insufficient parallelism? Serialization? Load-imbalance? Task dependences? Idleness? Data movement costs? Power or energy consumption? Failures and failure handling costs? The overhead of resilience mechanisms?

| What kinds of performance problems do you foresee analyzing using on-the-fly analysis? What interfaces will be needed to gather the necessary information? What control interfaces will be necessary to enable runtime adaptation based on performance measurements?

|
| There is a gap between the application-level and implementation-level views of programming languages and DSLs. What information should your software layers (compiler and runtime system) provide to attribute implementation-level performance measurement data to an application-level view?
