Code to test the performance of matlab code and benchmark algorithms is now available here: perf. It uses the internal matlab walltime (tic/toc) and cputime functions as well as the PerformanceApplication Programming Interface (PAPI) using hardware counters for floating point operations, instructions, cycles and the PAPI real-time timer. It also counts m and builtin matlab function calls using matlab’s profiler. It’s mainly aimed at iterative algorithms.
See perf_test.m for some usage examples to collect the information and plot the results. Collecting information is done via perf_profile for the function call counters and perf_timing for the timers and PAPI counters. Use perf_profile_plot to plot and perf_timing_plot to plot the results. Iterative code needs to call perf_record_iteration(v) after each iteration to collect counters and timing information per iteration, where v is the value (vector) result for the current iteration.
The whole package still needs some detailed documentation and will be integrated with the Qyber package, mainly to test algorithms related to quantum engineering. For now this is an initial test version.

…or rather the lack of it means I have not added much here in the last couple of months. It’s really not surprising, though, and this will remain a rather random and incomplete collection of notes.
However, to simplify things I’ve removed the associated wiki and only keep the blog here. Any wiki type entries better go onto the wiki of the development sites associated with the projects or my home page.
The other change is that this will now not only be about my work, but anything that I come across or produce that looks as if I should put it somewhere publicly accessible. Hopefully all the sites, content, etc. have been updated to reflect this.
