The mysteries of Cellular Automata

-
I recently bought Stephen Wolfram's book "New Kind of Science". The book is interesting and I highly recommend it.
In the spirit of one of my favorite phrases by Confucius:
"I hear and I forget. I see and I remember. I do and I understand" I decided to reproduce some of the first examples that are given in the book. I wrote about 100 lines of Python code and enjoyed the beauty of the results.
The whole book is available online and I am referring here to the plots on page 55. Below enclosed a few of my plots.

Rule 25:


Rule 22:


Rule 30:


Rule 60:


Rule 73:


It is still a mystery for me the richness of the patterns that are produced from very simple interaction rules.
I would call it Social Networking by pixels.

Cellular Automata - Part II, Using Condor

-
My post on Cellular Automata from January 12 was not put there by mistake. I want to use it as a starting point for a couple of exercises in my Parallel Processing course. In that post I gave a few drawings that differ only by the generating rule number. Today, I am going to show how using the Condor High-Throughput Computing system allows to handle in a very simple way large volume of computations. I used this simple Condor submit file : universe = vanilla executable = nks.py Error = err.$(Process) Output= out.$(Process) Log = log.$(Process) Arguments = $(Process) Queue 256 And was able to compute the whole set of 256 rules (jobs) with the same effort of computing a single rule. I submitted the task to my Personal Condor on my laptop and was not disappointed; After a while I got all the outputs happily waiting for post processing.

The End of Grid Computing?

-
Image
In the year 2003 the MIT Technology review ranked "Grid Computing" among the 10 Emerging Technologies That Will Change the World [1]. We are now four years later and something is not going well with "Grid Computing". An indication that there is a problem can easily be seen by looking at the "Google Trends" plot for the term "Grid Computing": (click on the image to get the current trend). This finding can be compared with another buzz word, "Virtualization", which is older than "Grid Computing" and yet is gaining more and more momentum: There is however one exception. The Academic Grid is still having lot's of glory thanks to the huge heavily funded European (EGEE) and other US projects. When LHC data will start to be taken at CERN it will reach it's top importance. But, it seems that for other scientific projects Grid Computing is not going to be such a success. It will remain as "Nice to have" but will never
