Summary of DSA Group Activities at EGEE08

If you followed us at GridCast during the EGEE08 Conference, you would surely have realized that it has been a busy week. Here you may find a little summary of our activities, not considering all the internal meetings where we were participating.

Our week started on Saturday 20th, when a Training Event took place. It was devoted to gLite and the RESPECT (Recommended External Sofware for EGEE CommuniTies) Tools. Being GridWay one of these, I gave a Tutorial where users learned everything from the user point of view, from Command Line Interface to the DRMAA API. The last part of this Tutorial was devoted to questions from attendees, who were already installing GridWay in their “Home Grids”.

On Tuesday 23rd, our group had a double participation at the Demo/Poster Session. Firstly, Javier was presenting a Poster devoted to OpenNebula, showing how it transforms a physical infrastructure into a virtual infrastructure by dynamically overlaying VMs over physical resources. He complemented the poster with a demo which helped the many visitors to understand this technology.

In the meanwhile, I was conducting a demo of a Bioinformatics application running on the Grid using GridWay at a Demo Booth devoted to the EGEE Grid Application Porting Support Group. The aim of this group is to help users on their road of application porting onto the Grid. This task is accomplished by providing information and training about procedures and technologies. Additionally, our Demo Booth was given the “Best Demo” Award by the EGEE Project Office! The second one in an EGEE Conference!

On Wednesday 24th, Tino gave a Talk where he explained the many important benefits of using the OpenNebula engine in your working environment, such as cluster consolidation, high availability, support for planned maintenance and changing capacity availability, performance partitioning, protection against malicious use of resources… Regarding user interaction, he remarked that its main benefit is the support for heterogeneous workloads with multiple (even conflicting) software requirements, allowing the execution of software with strict requirements as jobs that will only run with a specific version of a library or legacy application execution.

And finally, Thursday 25th was the busiest day of the week for us. Firstly, Eduardo gave a Talk where he highlighted the workload capabilities of GridWay, so attendees could understand the benefits of this technology for both Grid users and administrators.

Next Talk during the day was given by Ignacio. He explained how Cloud Computing could be a solution for supporting Grid Computing. This Talk also served as a wrap-up of the rest of OpenNebula related presented works. This new paradigm and its implementation with OpenNebula attracted many interested people, so Rubén performed a Demo at the end of the Session.

And the last Talk at EGEE08 was mine. There I showed some working examples of application that were ported onto the Grid and are running at production state. We understand that as there are no users alike, the same happens to applications that need Grid Computing. This was the reason of why I remarked the specific difficulties of each application and how they had been bypassed.
