Customer Reviews

"We reached our final goal of 1080p100 [frames per second] encode in a single thread. The use of Intel VTune Amplifier and the Intel Advisor vector tool have been critical to achieving this success. The two and a half times [the] performance gain allowed us to offer more than double the capacity at the same price point. For us, that translates into a major competitive advantage."

Lars Petter Endresen, PhD, principal performance engineer

"Intel VTune Amplifier helped us identify system performance issues by analyzing and displaying CPU utilization, cache misses, and more, across multiple processors and server products. We optimized our product based on this analysis, improving overall performance by 12 percent on key workloads. Intel VTune Amplifier was invaluable [by] quickly identifying optimization opportunities in our product."

Charles Liu, solution integration
Server Product Business Unit, Acer Inc.*

"We very quickly prototyped our core algorithm and obtained performance considerably higher than with any other processor architecture. The Intel® C++ Compiler exploited vectorization opportunities and Intel VTune Amplifier quickly identified a threading bottleneck that was simple to fix. Porting and tuning the kernel for the Intel® Xeon Phi™ processor was quick and efficient."

Georg Viehoevers, senior staff engineer research and development
Silicon Engineering Group, Synopsys*

"We achieved a significant improvement of almost two times—even on one core—by optimizing the code based on the information provided by Intel VTune Amplifier. Good scalability resulted from the combination of Intel Threading Building Blocks and OpenMP* parallelization techniques. We achieved over eight times the performance of the previous version on eight cores and almost eleven times [the] performance on 16 cores."

Alexey Andrianov, deputy research and development director
Mechanical Analysis Division, Mentor Graphics*

"Intel VTune Amplifier analyzes complex code and helps us identify bottlenecks rapidly. By using it and other Intel® Software Development Products, we were able to improve PIPESIM* performance up to 10 times compared with the previous software version."

Rodney Lessard, senior scientist

"The new Intel VTune Amplifier brings even more capability to an already indispensable tool. The sampling-based call stack hotspots are excellent and alone are worthy of the upgrade. We have also been impressed by how the concurrency and Locks and Waits analyses can even provide useful data on complex applications such as Premiere Pro*."

Rich Gerber, engineering manager
Adobe Systems Inc.

"Where this tool really shines is profiling OpenMP* code. We were able to achieve almost linear scaling in our application thanks to Intel VTune Amplifier."

Jaroslav Šindler, researcher, faculty of mechanical engineering
Czech Technical University

"The new interface is a joy to use. Intel VTune Amplifier gives us precise, down-to-the-metal performance data that’s invaluable for pinpointing hotspots and evaluating the effect of optimizations."

Daniel Schwarz, performance engineer
Nik Software

"The Intel VTune Amplifier timeline is very information intensive. It organizes the data I need to tune threaded applications."

Sergey Zaritchny, software development manager
Open Cascade SAS*

"One of [the best features of Intel VTune Amplifier] is that it is easy to use. I did not need to read the documentation."

Richard Shepherd, software engineer
Esri* (UK)

"Intel VTune Amplifier is essential for any serious production code if performance is key. I was able to make code run twenty times faster than our prototype version while handling five times the data load."

Artur Guzik, senior engineer
Neubrex Co. Ltd* (Japan)

"Intel VTune Amplifier helped us identify potential performance bottlenecks in the design and engineering of our extremely complex, high performance networking systems."

James Hendergart, strategic initiatives director
F5 Networks

"Simple performance bottlenecks can remain hidden until you look for them with a good profiler. Case in point, when the National Laboratory for Scientific Computing (LNCC) high-performance computing (HPC) team analyzed the radiation scheme driver for [the Brazilian Regional Atmospheric Modeling System (BRAMS)] with the Intel VTune Amplifier performance profiler, it helped us detect redundant array initializations inside a loop. Moving these before the beginning of the loop made the driver nearly 1,500 times faster than before. Using the optimized version of the driver, we obtained approximately a 19 percent overall run-time reduction for BRAMS, an important reduction for the forecast runtime. The next step for the LNCC HPC team is to use Intel Advisor to identify regions for vectorization optimization."
