We have just released version 1.2.0 of Heaptrack, the fast heap memory profiler for C++/Linux applications. A bit of Background The Heaptrack fast heap memory profiler allows you to track all heap memory allocations at run-time. Afterwards, you can use the accompanying GUI tool to find optimization opportunities in your code by analyzing the recorded […]

We are pleased to announce a new release of our Hotspot Linux perf performance analysis GUI, Hotspot version 1.3.0! Hotspot is a replacement for perf reportthat takes a perf.data file, parses and evaluates its contents, and then displays the result in a graphical form. You can read a bit more about Hotspot here: https://www.kdab.com/hotspot-gui-linux-perf-profiler/ Overview […]
Did you miss the past Qt World Summit? Were you there, but you couldn’t attend that talk or two that you really wanted to see because the conference was so, so packed with awesome content? Fear no more! We are glad to announce that the talks at the past Qt World Summit 2019 in Berlin […]
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, […]
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...
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.
