Dominic, this is a ROMIO error message, and ROMIO is from MPICH project. at first, I recommend you try the same test with the latest mpich, in order to check whether the bug is indeed from romio, and has been fixed in the latest release. (ompi is a few version behind the latest romio)
would you be able to post a trimmed version of your application that evidences the test ? that will be helpful to understand what is going on. you might also want to give a try to mpirun --mca io ompio ... and see whether this helps. that being said, I think ompio is not considered as production ready on the v1.10 series of ompi Cheers, Gilles On Tuesday, March 15, 2016, Dominic Kedelty <dkede...@asu.edu> wrote: > I am getting the following error using openmpi and I am wondering if > anyone would have clue as to why it is happening.
