MPI IO problem with intel mpi v. 4.0.1.007 -

We upgrade to Intel compiler V12 with impi 4.0.1.0007, a small mpiio code with simple mpi_file_write_all(...) failed to run with error message "...File locking failed in ADIOI_Set_lock...." Roll the impi back to 4.0.0.028, same code run fine. Any advice? Thanks. -- Terrence Liao

Hi Terrence,

You probably work on parallel file system. Then you need to set file system explicitly:
Set I_MPI_EXTRA_FILESYSTEM=on and I_MPI_EXTRA_FILESYSTEM_LIST=lustre (or pvfs2 or panfs)

Let me know if you still see the error.

Regards!
Dmitry
