------- Forwarded Message Hello All, A group of researchers at Northwestern University and Argonne National Laboratory (Jianwei Li, Wei-keng Liao, Alok Choudhary, Robert Ross, Rajeev Thakur, William Gropp, and Rob Latham) have designed and implemented a new parallel interface for writing and reading netCDF data, tailored for use on high performance platforms with parallel I/O. It is based on netCDF-3 file format. The parallel implementation builds on the MPI-IO interface, providing portability to most platforms in use and allowing users to leverage the many optimizations built into MPI-IO implementations. Testing so far has been on Linux platforms with ROMIO and IBM SP machines using IBM's MPI. Documentation and code for Parallel-NetCDF version 0.8.5 is now available for testing: http://www-unix.mcs.anl.gov/parallel-netcdf/ Although a few interfaces are not implemented yet, the current implementation is complete enough to provide significant I/O performance improvements on parallel platforms, as described in the technical report: ftp://info.mcs.anl.gov/pub/tech_reports/reports/P1048.pdf Users are invited to test Parallel-NetCDF in their applications. Features not yet implemented include: - uchar, schar, or long data types - get/put_varm data access functions - MPI derived datatype for flexible data access interface - NC_FILL (no plan to implement) Thanks for your interest.

I have a set of VB.NET declares which allow you to call the netCDF windows dll from VB.NET. I've also wrapped this in a Dataset object, which contains Var and Attribute object, in the expected netCDF way. At the moment I only read netCDF files. I can add writing if there is any interest. We'll have this up on the web server at some point soon. In the meantime, anyone who's interested can email me directly and I'll mail the source to you. Ed Hartnett
