Guy Tel-Zur's Blog

About four years ago I predicted in this blog the fall of Grid Computing and the rise of Cloud Computing (  http://telzur.blogspot.com/2007/10/end-of-grid-computing.html  ) Now I want to claim that Supercomputers as we know them today will not be the kind we will see in the future. I think that within a couple of years: 1. Most supercomputers will shift to the cloud (HPC Cloud). 2. The governance of X86 is not guaranteed: We already see the rise of GPGPUs and we will see more families of technologies being involved, e.g. Tegra and ARM, Reconfigureable Computing (RC) i.e. FPGAs, etc'. 3. Supercomputers won't be anymore General Purpose machines. They will be reconstructed as a Cloud Service ( Supercomputing as a Service ) from all the available technologies (see previous section) per single mission (program) in order to maximize the performance and minimize the consumed energy and cost. I decided to use the word mission because the word  task is u...

not so good :(

First trials with Xcerion XIOS/3 Beta. A remote OS and applications consumed completely from the "Cloud". All you need is a Web Browser. Xcerion looks cool although at the moment it works only on top of IE6+ and not yet on top of Firefox. The response time is reasonable and the Windows Manager is nice and intuitive: (click on the image to enlarge) A thin client/OLPC and Xcerion can be an interesting cheap computing platform.

I followed the Hadoop Quickstart guide and the whole process is described below. This post can be used as a reference for other people installing Hadoop. My system is OpenSuse 10.3 and Java version is 1.6.0_03. After downloading and installing the package I did the Standalone operation test : $ mkdir input $ cp conf/*.xml input $ bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+' $ cat output/* Here is the output ( line feeds may be corrupted, sorry for that ): gtz2:/home/telzur/downloads/hadoop-0.14.4 # bin/hadoop jar hadoop-0.14.4-examples.jar grep input output 'dfs[a-z.]+' 08/01/05 15:47:13 INFO jvm.JvmMetrics: Initializing JVM Metrics with processName=JobTracker, sessionId= 08/01/05 15:47:13 INFO mapred.FileInputFormat: Total input paths to process : 3 08/01/05 15:47:13 INFO mapred.JobClient: Running job: job_local_1 08/01/05 15:47:13 INFO mapred.MapTask: numReduceTasks: 1 08/01/05 15:47:13 INFO mapred.LocalJobRunner: file:...
