The Computing Service and its researches obtained good results in 2013

July 15th, 2014

2013 year report

The Computing Service IZO-SGI SGIker of the UPV/EHU has published the 2013 year report, which can be found in the next link:

IZO-SGI 2013 year report (pdf in spanish)

The Computing Service has increased or maintained their main indexes as can be observed in the table below. Among the positive indexes, we can mention the increase of scientific publications, the increase in the use of the machine without a noticeable impact in the waiting time and the increase in the number of visits of the blog. In the negative part, we had ta drop of visits to the web page and the decrease of computing resources due to failure. The Service continues having an excellent score in the satisfaction poll between the researches.

 

Acknowledgments

We would like to acknowledgment to all the researchers that have relied on the service, most of the good results of the Service are in fact their merits and not ours.

¹ Satisfaction pool by the SGIker Quality Unit.
² Where the IZO-SGI is acknowledged.
³ The use in 2010 is apparently low because new machines where installed passing form 300 cores to 752 cores in July. In August and September Arina was quite empty and the weigh of these months has had a lot of importance in the mean value. In fact in November the mean use was already in the 76%.
Jobs with less than 2 minutes of computing time are usually failed jobs. In any case due to the short duration they don’t have relevance in the usage.
The jobs with less than 2 minutes of computing time are not taken into account.
The jobs are executed through a queue system that assign proper resources to the jobs. The waiting time is the time the jobs spend in the queue waiting for the resources to be available.
The machine was switch off in April.

2013 Arina year use

Use of Arina between 2012 December and 2013 November.
