Histograms
I now have the ability to create summary histograms characterizing the workloads. These are (re)-generated as I update performance reports, but following is values with ~170 workloads added. Walking through the histograms and what they describe… Most of the runs … Continue reading →
Adding summary statistics for all benchmarks
After adding general parsing of measurement statistics, I can now also create a statistical summary across all ~170 benchmarks as shown below. This lets me see for example the minimum IPC, maximum IPC, mean IPC and standard deviation. This will … Continue reading →
Creating a more automated performance table
I have been maintaining a table by hand with various performance metrics – both on the website and separately in Google Sheets. In addition to the extra work required, I also by nature only put some of the columns. So … Continue reading →

I am now up to 50 phoronix workloads as summarized on the workloads page. For each one I have a graph and some pages of information. My general idea is to take the benchmark-based Phoronix articles and see if I … Continue reading →
Turning on counters for l3 and data fabric measurements on AMD
By default, counters were not available to measure l3 and df counters on AMD. With some help from likwid documentation I figured out what is going on and how to get it enabled. The first thing to do is see … Continue reading →
