ECMWF Data Handling log traces

At the Usenix Fast'15 conference in February 2015, the PhD student Matthias Grawinkel presented a paper named "Analysis of the ECMWF Storage Landscape" describing the user access to our then 100 PB archive. The presentation can be seen on the Usenix website: https://www.usenix.org/conference/fast15/technical-sessions/presentation/grawinkel

In order for other people to pick up where he left, the obfuscated logfiles are available for download here on this site.
