What kind of parallel environment are you in? this error looks like, for example, you are in a parallel environment where files exist on one system but not another. What file name are you passing to your open call? Which file access method are you using? MPI-IO or MPI-POSIX? ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Hdf-forum is for HDF software users discussion.
