Customers need to predict how many concurrent users can be accommodated on a Sim. In OpenSim were used to a maximum of 50 avatars or even less, depending on the number of prims.

The aim of the OSGRID people was to test if the SIM code improvements made in recent weeks have been effective.

The test was made on 9 October 2009.

Their goal was to reach the 100 users (the magic number) and the result is impressive because they managed to accommodate 85 real avatars(not bots). And the server did not crash, it was still accepting connections when they reached 85, people simply stopped logging.

So how did they do it? The answer lies in three points:

1) They abandoned Openjpeg technology to decode the J2K textures

2) Using the experience of Intel’s John HURLIMAN to rewrite the server code. It remarkable that the arrival of people from IBM and Intel is pushing up the quality of OpenSim

3) Improved management of server memory.

The result is impressive, 85 avatars on an old server with less than 1 GB of RAM.

Dot has made a very successful virtual presentation for students in  the Pau engineering faculty of EISTI (www.eisti.fr). The purpose of the event was hiring trainee engineers to develop a project in OPEN SIM.

Thanks to this Second Life presentation DOT saved as much as 30,000 km in travelling, 300 hours of work and 9000 euros. Each of the 5 speakers from DOT was in their own city (Madrid (2), Pamplona, Zürich (Switzerland) , Mendoza (Argentina).

Eisti Auditorium, presentation of DOT

EISTI is a prestigious engineering school located in Pau (Pyrenees Atlantiques) and Paris. EISTI also belongs to PEBA (E-Business Pôle sud Aquitaine, which brings together ICT companies of the French departments of Pyrenees Atlantiques and Landes (see the post about Navarre-Aquitania meetings in Second Life). 

The event took place on November 20 at noon in the auditorium of the Engineering School in Pau and like other companies in new technologies, DOT sought to convince EISTI engineers to join our own Open Sim project.

But unlike other companies that shared the EISTI auditorium with us, the DOT speakers used Second Life. Our presentation in real time was seen and heard by students in the auditorium of EISTI. We also interacted with them in an event that mixed the real (the auditorium with its 50 students) with the 5 DOT speakers.  

DOT speakers that day: Eduardo (who was in Madrid that day), Estíbaliz (Madrid), Diego (Pamplona), Volker (Zurich, Switzerland, was in the airport) and Rodolfo (Mendoza, Argentina). All in all almost 30,000 km. saved, 300 hours of travel and 9000 euros. Mikel should make the calculation of CO2 savings (see the post Mikel: Second Life to combat climate change)

And in addition to the speakers, there were other people from the DOT as Yolanda Amatriaín, Javier Selva , Mikel Meoki, Germán Pérez,  Enrique Bauluz, or Juankar Sanz or Mikel Belasko Mikel.

The presentation (about thirty-five minutes), was a success, judging by the applause of the audience at the end and the words of the director of Campus EISTI of Pau, Laurence LaMoulie: “La présentation a été très appréciée de nos élèves et des professeurs de l’EISTI, tant pour sa technicité que pour son originalité. Ceux qui n’y ont pas assisté le regrettent déjà: elle a été la plus remarquée de la journée “(The presentation was highly appreciated both by our students and by the teachers, for its technique and for its originality. Those who do not have been able to attend, are already regretting it).

DOT is creating a virtual space for associations ATANA (Navarre, www.atana.org) and PEBA (Aquitania, www.peba-pyrenees.com). 

On the 5 and 6 November was held in Pau (France) the 2nd meeting of ICT companies of Aquitaine and Navarre. The meeting was part of the project of collaboration between the association Atana, Association of ICT firms of Navarre and the association PEBA, Pôle E-Business sud Aquitaine, which brings together ICT companies of the French departments of Pyrenees Atlantiques and Landes. The first meeting between enterprises of both associations took place in Pamplona in early October. 

DOT will provide infrastructure and training for both associations so that they can remain in contact via a private virtual space for communication. In this way, they may continue their collaboration on joint projects. 

This initiative forms part of the project ANBTIC “Aquitaine - Navarre ICT Business: Development of cross-border business cooperation in the ICT sector, designed for companies associated with ATANA-PEBA. 

In the same meeting Dot moved in collaborative projects with EISTI (Ecole Internationale des Sciences du Traitement de l `information www.eisti.fr) and BIP INFO (www.bipinfo.com) seeking to apply the advantages of virtual reality to businesses.
