Subject: [OMPI users] ADIOI_Set_lock failure
From: Brock Palen (brockp_at_[hidden])

Using OpenMPI-1.2.3+pgi-7.0+hdf5 parallel + lustre is giving me the

File locking failed in ADIOI_Set_lock. If the file system is NFS, you
need to use NFS version 3, ensure that the lockd daemon is running on
all the machines, and mount the directory with the 'noac' option (no
attribute caching).
[] MPI_ABORT invoked on rank 0 in
communicator MPI_COMM_WORLD with errorcode 1

Has anyone else managed to use hdf5+lustre+openMPI's romio setup? I
can do MPI_File_wirte and MPI_File_read just fine.
