"Interperformant Systems Ltd. was faced with a challenge: Our customer wanted to optimize a manually coded algorithm that had been working for years. We used Intel® VTune™ Profiler to quickly identify the problematic areas of the code. After vectorizing the code using Intel® Advanced Vector Extensions 512 (Intel® AVX-512), we used the Intel VTune Profiler feature, which allowed us to run tests on a repetitive algorithm on certain system loads with multiple targets. We determined which part of the code was consuming CPU time, were able to observe the underlying behavior of the microarchitecture, and ended up with a 30% overall speedup. If you want the best possible system performance, I highly recommend using Intel VTune Profiler."
