How #supercomputer #filesystem #DAOS breaks out of its niche
DAOS parallel filesystem has strong #IO500 presence, holding 1 (Argonne) and 2 (LRZ) in #SC25 list. The two, according to #HPE, combined have four times storage benchmark score of next 30 systems. DAOS also appears at number 13 (Zuse Institute, Berlin), and 17 (China Telecom). Software appears more often in the full IO500 list, with 16 of the top 30 submissions using DAOS, and 26 of top 45 being DAOS devotees.

Great talk by Mark Nelson from Clyso (Ceph company) in the #io500 bof on how they use the io500 benchmark to improve Ceph performance and regression test developments. Really nice to see a benchmark used productively to improve performance. #HPC #SC24

It's been over two years(!) since the last release of the #IOR and #mdtest #HPC I/O benchmarks, so we just cut a candidate for 4.0.0 based on the version used for the #SC22 #IO500 here: https://github.com/hpc/ior/releases/tag/4.0.0rc1

PLEASE kick the tires since there have been huge changes since 3.3.0 came out.
