We've all shared the frustration when it comes to errors - software updates that are intended to make our applications run faster inadvertently end up doing just the opposite.

These bugs, dubbed in the computer science field as performance regressions, are time-consuming to fix since locating software errors normally requires substantial human intervention.

To overcome this obstacle, researchers at Texas A&M University, in collaboration with computer scientists at Intel Labs, have now developed a complete automated way of identifying the source of errors caused by software updates.

"Updating software can sometimes turn on you when errors creep in and cause slowdowns. This problem is even more exaggerated for companies that use large-scale software systems that are continuously evolving," said Dr. Abdullah Muzahid, assistant professor in the Department of Computer Science and Engineering.

To pinpoint the source of errors within a software, debuggers often check the status of performance counters within the central processing unit.
