I'm trying to write a TIFF file in MPI code. I mean different PEs read different parts of the file, process data and write it to the file. But the write fails, only the 1st PE can write to it. Has anyone here done this kind of work?

Otherwise there is MPI-IO which permits parallel o/p, but these functions have their own API, it is difficult to write wrappers for the TIFF lib. like TIFFWriteTile, the file ptr. TIFF *.

I will have to try to write some kind of wrapper functions.
