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. If so, investigate.

What Customers Say… About current Intel® Parallel Advisor “The Intel Parallel Advisor “Intel Parallel Advisor is an design approach was excellent tool for use in instrumental in conjunction with a class on introducing parallelism parallel programming, enabling into our code . The Survey students to quickly comprehend feature helped improve the theory of parallelism and our code by finding areas in implementation .” our serial code that took a lot of CPU time, and where our code would benefit from parallelism.” Korbinian Molitorisz Dr. William Orttung Dipl.-Inform, Karlsruhe Emeritus Professor Institute of Technology” of Chemistry Kirk Haller, Director of “Leveraging Intel Parallel Advisor, we were able to test our ideas, and Research at Dassault determine where to spend our development effort . With the help of Intel Systèmes SolidWorks Parallel Advisor, we achieve the performance scaling we were hoping for, Corporation and saved a lot of effort and frustration ." ” Copyright© 2012, Intel Corporation.
