I just read in Supercomputingonline about EGEE III, the 3rd phase of the gigantic Grid Computing project: " EGEE-III will last for 24 months, with a total manpower bid of almost 10,000 person months and an EC budget of Euro 36 million. As with EGEE-II, partners will provide extra effort to the project beyond that funded by the EC, bringing the total project budget up to Euro 70 million, and also contributing a further estimated Euro 50 million worth of computing resources." and I ask myself what is more justified , a single extended 3PFLOPs BlueGene/P with 884,736-processors or thousands of various kinds of old 32 bit boxes distributed all over the world running Scientific Linux 3.0.X and gLite? For years we were told that no single data center site will be able to cope with a few PB of data per year that will be produced by the LHC; Nice Powerpoint presentations showed a 20km tower of CDROMs, higher than the Mt. Blanc, indicating that only distributed Grid Computing environ...

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...

I participated in the Grid Computing school, GridKa2007, that took place in Karlsruhe, Germany.

Eclipse version 3.3 does not work out of the box on Sabayon Linux (Gentoo). It likes Java 1.6. Upon installing this JDK from SUN there was a strange error message that "run-java-tool is not available". Then, I noticed that /usr/bin/java was pointing to /usr/bin/run-java-tool. I know that it was invented with some good reasons but in order to start playing quickly with Eclipse I just removed this link and put instead: "ln -s /usr/lib/jvm/sun-jdk-1.6/bin/java /usr/bin/java", then Eclipse was happy and me too!!! Enjoy Eclipse

June 28th, 14:00-16:00 - Grid-HPC Work Group meeting Location: IGT Offices, Maskit 4, 5th Floor, Hertzliya Agenda: 14:00-14:15: OPENING - Avner & Guy 14:15-14:50: DEBUGGING AND OPTIMIZING APPLICATIONS FOR MULTICORE MPP ARCHITECTURES Speaker: Jacques Philouze, Vice President Sales & Marketing, Allinea Abstract: As two, four and potentially eight-core processors become the norm, the defacto HPC architecture is tending towards large clusters of modest 8-16 core shared-memory servers, potentially with co-processing devices (eg. GPGPUs, FPGAs, Clearspeed). Programming these machines optimally presents a number of challenges, and applications that use a mixed programming models are now becoming commonplace. In this presentation we will discuss the challenges facing today's HPC application developers, and the need for simple tools that can address mixed programming models. We will present new multicore features of Allinea's Distributed Debugging Tool (DDT) and Op...

Very simple: type "df" to find the dvd file system name, then: dd if=/dev/dvd_fs of=mydvd.iso That's it!
