KIK-IRPA : Over one million images in detail
Here is an excerpt from this article :
“A major problem however, was the duration it would take to convert over one million images in our database. With 20 seconds to convert one image of 35 megabytes, it would take over 5500 hours – almost one year -, not even including the annual growth of our photo collection.
To tackle this problem, grid computing was used to spread the work over many CPU’s so that the calculations are carried out simultaneously and with the BE-grid infrastructure at our disposal, the total conversion time reduced considerably.”
“One of the hot topics in particle physics is the so-called reactor antineutrino anomaly, i.e. that less antineutrinos are observed than expected at a short distance from nuclear reactors. The SoLid experiment aims to solve this anomaly. The experiment is installed at about 7 metres from the core of the BR2 reactor at the SCK°CEN in Mol (Belgium). Since December 2017, the experiment collects about 1.5 TB of data per day. The data is transferred from SCK°CEN to the BEgrid, from where it is further distributed on the European grid infrastructure to grid sites in the UK and France. The raw data is centrally processed for further analysis at one of these sites. The data is compared to simulation. Since the simulation is very CPU intensive, hundreds to thousands of jobs are run in parallel on the grid. The collaborators of the SoLid experiment are all connected to the same Virtual Organization, which allows for accessing and analyzing the observed and simulated data files located at a different geographical location.”
