The file locking comes from the MPI-IO layer. You can disable data sieving at the MPI-IO layer and get around this problem. through an HDF5 property list you can set the MPI-IO hints "romio_ds_read" to "disable" and "romio_ds_write" to "disable". ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Hdf-forum is for HDF software users discussion.
