Unanswered Questions

How does this technology handle complex dependencies between multiple tasks in a system?

This technology uses observed delays to determine causal relationships between tasks, but it may face challenges in analyzing intricate dependencies in highly complex systems. Further research and development may be needed to address this issue.

Can this technology be applied to real-time systems with strict timing requirements?

While this technology focuses on analyzing delays between tasks, its applicability to real-time systems with stringent timing constraints is unclear. Additional testing and validation would be necessary to assess its suitability for such environments.


Original Abstract Submitted

An electronic device includes: one or more processors; a memory storing instructions configured to cause the one or more processors to: install instrumentation points in respective tasks of an application, the instrumentation points including a source instrumentation point installed in a source task and a target instrumentation point installed in a target task, wherein the source task and the target task are configured to execute in parallel on the one or more processors, and wherein each task includes a respective sequence of instructions executable by the one or more processors, and determine a measure of a causal relationship between the source instrumentation point and the target instrumentation point based on observation of a delay in the target instrumentation point induced by a delay amount generated by the source instrumentation point.
