Improving Python performance by factor of 100

Posted on September 9, 2017 by swdevperestroika

I’m doing a bit of Machine Learning on my spare time. A neural network that analyzes images. Anyways, since I don’t have zillions of computing power, any decent amount of learning data takes hours and days to process thru my … Continue reading →

Algorithm analysis – Big O notation

Posted on February 5, 2014 by swdevperestroika

Continuing from my previous post on performance analysis of algoritms, I decided to plot the CPU-time over the size of the problem, that is, the number of cells. The two graphs above, both plotted ‘log-log’, demonstrate a straight line.  A straight … Continue reading →

Single simulation run consuming 230 h (!) of cpu-time – root cause analysis of performance

Posted on February 5, 2014 by swdevperestroika

I think I’ve broken some kind of record of CPU-time consumption for a single simulation run… for a fairly trivial application… As my frequent readers know, I’ve been playing lately with a simulation of Shelling’s segration model (see previous posts … Continue reading →
