Hello, I have a very specific usage question.
I would like to output a part of an array. Other libraries may call this a slice. By way of an example, say I have a 3 dimensional array with a size of 5 in each direction spread over several separate processes. I would like to write to file all the data with y coordinate 3. I currently use parallel file I/O by hyperslab, following the example here: https://support.hdfgroup.org/HDF5/Tutor/phypecont.html It seems to me that there might be a very easy way to do this using the memory and file datasets which doesn't require my code to check each process for participation in the output, etc, but I have failed to find examples or documentation that outline the constraints. Any help is appreciated. -- Aaron Friesz
