_______________________________________________I assume the top500.org systems are for applications different from those of io500. After all, top500.org, in my opinion, are more related to scientific computation, in which the scientific problems to solve is not embarrassingly parallelizable. For io500, I'd expect more embarrassingly parallelizable applications. In such cases, the storage size is more important, and the write/read pattern should be more serial. This probably explains the big difference between the two.Maybe others can also share their opinions on the difference.--On Tue, Sep 17, 2019 at 1:57 PM John Bent <johnbent@gmail.com> wrote:Thanks Patrick. Peng, here's something else from Cray showing that Lustre was the file system on 77% of the top 100 systems from the June 2018 top500.org list:Which is not nearly the same ratio that we have seen thus far in IO500:Which I just created using https://www.vi4io.org/assets/io500/2019-06/data.csv ("The list shows the best result for a given combination of system/institution/filesystem"). Note that I did combine a few to reduce the number of slices (e.g. s/GPFS/Spectrum Scale/).Regards,
