Intel® VTune™ Amplifier XE The Old Way versus The New Way The Old Way: To see if there is an issue with branch misprediction, multiply event value (86,400,000) by 14 cycles, then divide by CPU_CLK_UNHALTED.THREAD (5,214,000,000). Then compare the resulting value to a threshold. If it is too high, investigate. The New Way: Look at the Branch Mispredict metric, and see if any cells are pink. -

Intel® Inspector XE 2013
MEMORY AND THREAD DEBUGGER Product Brief Intel® Inspector XE 2013 Top Features Deliver More Reliable Applications . Inspect C, C++, C# and Fortran Intel® Inspector XE 2013 is an easy to use dynamic memory and threading error detector for . No special builds required. Use Windows* and Linux*. Enhance productivity, cut cost and speed time-to-market. your normal compiler and build. Find memory and threading defects early in the development cycle. The earlier an error is . Inspects all code, even if the found, the lower the cost. Intel Inspector XE makes it easy to find and diagnose errors early. source is unavailable . Highlights the error at multiple Find errors that traditional regression testing and static analysis miss. Intel Inspector XE source code locations, provides finds latent errors on the executed code path plus intermittent and non-deterministic errors, corresponding call stacks even if the error-causing timing scenario does not happen. New! Debugger breakpoints for easier diagnosis of difficult bugs Memory Errors Threading Errors . New! Heap growth analysis finds . Memory leaks . Data races cause of heap growth in a . Memory corruption and Illegal Accesses - Heap races problematic region . Allocation / de-allocation API mismatches - Stack races . Inconsistent memory API usage . Deadlocks “We struggled for a week with a crash situation, the corruption was C, C++, C# and Fortran. Or any mix. Is your GUI in C# with performance sensitive code in C++? identified but the source was Got legacy code in Fortran? Using libraries without the source? No problem, it all works. really hard to find. Then we ran Dynamic instrumentation enables inspection of all code including third party libraries where the Intel® Inspector XE and source is not available. -
