[mpich-discuss] How to read data using user-defined functions in Parallel-IO?

[Manoj Vaghela]

Hi,

      Let say, in serial application, user-defined functions are used
to read a particular file format and extract data from it. Now for
same thing, I want to use these functions to read data in parallel
using MPI Parallel IO functions. Is it possible without going into
hardcore other programming stuff only using MPI and user-defined
functions?

PS: Input data file(which is to be read)  is in binary and
user-defined/library functions are required to extract contents from
that file.
