Grid Computing

Fun Facts


SNO+ takes data 24/7/365.   For the SNO+ water phase, we produced around 50TB/year of raw data.  The raw data is shared between Canada, Europe and the US via three grid sites.  The data is autoprocessed daily and the output is available to analyzers less than 24 hours after being recorded.



Access to Data


SNO+ has a virtual organization (VO) in order to make use of the European Grid Infrastructure.  The Grid is used as a means to distribute and store data among the SNO+ collaborators.  The software is available via the CERN Virtual Machine Filesystem. To access SNO+'s public datasets please see our Results page. The SNO+ Data Management Policy can be found here: SNO+ Data Management Plan
