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, […]

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 […]
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.
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...
CppCon is the annual, week-long face-to-face gathering for the entire C++ community – the biggest C++ event in the world. This year, for the first time, CppCon takes place in the stunning Gaylord Rockies Hotel and Convention Center in Aurora, Colorado, very near Denver International Airport. KDAB is a Bronze sponsor this year, and Milian Wolff is […]
KDAB has released a new version of KDSoap. This is version 1.8.0 and comes more than one year since the last release (1.7.0). KDSoap is a tool for creating client applications for web services without the need for any further component such as a dedicated web server. KDSoap lets you interact with applications which have […]
Once again, KDAB is proud to have sponsored Italian C++ – a free event organized by C++ enthusiasts in Milan, Italy. The program will soon be available for download, including a 50 minute talk from KDAB’s James Turner: Custom tooling for frameworks, libraries and projects using Clang – getting Clazy. We also exhibited two of […]
ACCU is the foremost annual conference in the UK for people interested in C++ and C, and runs from Wednesday the 10th to Saturday 13th April at the Bristol Marriott City Centre Hotel, with pre-conference tutorials on April 9th. Keynote Speakers on the 10th and 13th are Angela Sasse, Herb Sutter, Paul Grenyer and Kate […]
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.
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 […]
