Independent write

[Roger Ting]

Does the independent writing coordinate all the processors?
I mean i have a netcdf file which each processor will append a new entry
at the end of the file. For the append operation i use independent mode
writing operation. It seems like if processor 1 appends an entry at
position ith  and processor 2 also wants to append another entry to the
file, it will overwrite the entry at position ith because it doesn't
realise the processor has already append an entry there. 

Is there a way around this? Ideally, each processor can just append to
the file at position ith without worrying that another processor has
just already written to that position.
