Why We Need Automatic System Tuning
The computing world is dominated by general-purpose systems that need to perform well for a wide variety of applications. Take servers as an example: there are 10’s of millions of servers in the world that are running many families of applications, and they are... Read More
Continuous Optimization of Compiler Flags
One of the ways to improve code performance is to compile with the right flags. After all, compiler engineers have invested years and years into making compilers better, and in the process, they’ve added many flags that we can use. However, in order to achieve optimal... Read More
Turning General-Purpose CPUs into High-Performant Special-Purpose CPUs
During the last two decades, the amount of computing applications with different requirement characteristics has grown dramatically. Nevertheless, in most of the computing cases, we are still using the “same” General-Purpose computing engines (e.g. general-purpose... Read More
Using Averages, Percentiles, and Modes When Tuning Real-World Systems
Life isn’t always perfect… and neither is any system which is based on sampling of real-world systems. In many cases, the samples do not render a perfect normal distribution, but rather a skewed one. If we are to tune a system, whether manually or using an automatic... Read More
February 2020 Feature Updates
We have started the year off busy improving our products, releasing the following new features, and expanding to new use-cases! We hope you like these enhancements: Knob refinement A new post-processing step that refines the recommended settings by filtering out... Read More
How to Prepare a Load Test for the Purpose of Performance Tuning
Having worked on optimizing multiple environments and applications over the years, the main challenge our users face is how to properly prepare a load test for the purpose of tuning their applications. In order to make quality recommendations for system settings that... Read More
