extra info. I run the code with Darshan in CURIE cluster, where the code behaves nicely. Exactly the same code, run in exactly the same way produces a very nice Darshan I/O report (attached) for mode 3. Any hypothesis on why the other cluster is behaving so badly with this particular case? Thanks a lot for any help,
