Here's more or less how to get parallel MPI-IO out of netcdf-4 - start with hdf5-1.8.0-beta3 for now. - configure hdf5 for parallel I/O: (basically build hdf5 with mpicc) - get ahold of something newer than the oct 22 netcdf-4 snapshot. Ed committed some fixes to the configure process which make parallel-netcdf4 work even better ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B
