Another Google failure...this time the Calendar

After Gmail failure a few days ago, this is a red light warning to the Cloud Computing model that this technology is still not mature enough.

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
