In the previous two blogs in this series I showed how solving an apparently simple problem about loading a lot of data into RAM using mmap() also turned out to require a solution that improved CPU use across cores. In this blog, I’ll show how we dealt with the bottleneck problems that ensued, and finally, […]

GammaRay 2.11.0 Release
We have released version 2.11.0 of our Qt application monitoring tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.11 comes with a new inspection tool for Qt’s event handling, providing even more insights into the inner working of your application. Besides looking […]
Little Trouble in Big Data – Part 2 improving CPU utilization across cores
In Part 1 of this series we solved the problem of using mmap() to load large set of data into RAM all at once. The catch was that it still took too long. In this blog, I describe how we solve this.
Little Trouble in Big Data – Part 1 how to use mmap() to load a large data set into RAM
We got a call from a bioinformatics group at a European university. The problem appeared simple, how to usemmap() to load a large data set into RAM all at once. OK, no problem I thought...
KDAB at CppCon 2019 September 15-20

Making the Most of your Memory with mmap
Today’s complex applications can soak up megabytes, a memory management strategy is crucial for RAM intensive applications like image/video processing, massive databases, and machine learning.
Auto Innovation at Embedded World Nuremberg, Feb 26-28, 2019
In vehicle infotainment systems and instrument clusters are getting larger and more complex, requiring an exponentially growing base of software to drive them. Furthermore, KDAB finds that self-driving technology does not obviate the need for displays – in fact, autonomous technology seems to be accelerating the trend for larger and more capable graphics software. To […]
