Abstract: Techniques for region-aware memory bandwidth allocation control are described. In an embodiment, an apparatus includes a processing core and control circuitry. The processing core is to execute a plurality of threads. The control circuitry is to control use of memory bandwidth per memory region and per thread.

Abstract: Systems, methods and computer program products are described herein for testing a system that is designed to optimize the execution of code within an application or other computer program based on profile data collected during the execution of such code. The embodiments described herein utilize what is referred to as a “profile data mutator” to mutate or modify the profile data between the point when it is collected and the point when it is used to apply an optimization. By mutating the profile data at this point, testing of a system for optimized code execution can be significantly more thorough. Furthermore, such profile data mutation leads to a more scalable and efficient testing technique for profile-guided systems for optimized code execution.

Abstract: Debugging and testing are aided by removing portions of software which are not relevant to a particular scenario. Upon replay, scenario behavior occurs. A reduction tool selects a function exercised during the replay, disables it to provide a test version of the software, replays the scenario to the test version to produce a candidate behavior, and compares the candidate behavior to the scenario behavior. When the candidate behavior matches the scenario behavior the tool removes the disabled function, thereby providing a reduced version of the software which is functionally equivalent to the full version but has fewer functions to manage. The tool may also remove unexercised code. Trimming unexercised code and reducing exercised but irrelevant code may be interleaved. Caching, dynamic uniform resource locator mapping, hypertext markup language code refactoring, and/or avoidance of certain random elements may also facilitate exhibiting, testing, or debugging web applications.
