I'm still working through the netCDF4 feature list inhttp://my.unidata.ucar.edu/content/software/netcdf/netcdf-4/index.html?printer&unidata=47bd4c17e6a6f09cd7f34013dc8c1f6b
I'm not done reading and thinking, but here are a few comments on the "Parallel I/O" item, number 6. One thing that I think needs to be clear is that Parallel I/O will besupported for netCDF4 HDF5 files, not for netCDF3 files. I think there is also an implicit requirement that all APIs and features
from regular netCDF4 work as expected in parallel. (This is the case for HDF5.) Parallel support has two parts (not counting tuning and mainenance): * required API features * library featuresInterpreting the feature list as a description of tasks, I would note that the parallel support is mostly design work in the first year (making sure
we don't design something that can't be parallelized), and implemented in the second year. Notably, we might well release something withoutparallel, and might also put in chunking and other features before parallel. In other words, I'm not sure the order of items in the list is necessarily
chronological. -- Robert E. McGrath (HDF Java Team Leader) National Center for Supercomputing Applications University of Illinois, Urbana-Champaign Champaign, Illinois 61820 (217)-333-6549 mcgrath@xxxxxxxxxxxxx
