multiple processor read one file

[Zi-Hao Wei]

Hi

I have a question, when the communicator has more than one processors,
MatLoad routine would read the same binary file at the same time for
each processors.
But "large number of processors is hopeless", how can we deal with this issue?
I know maybe we can use one processor to read the file and assembly to others.
However, when large "size" of binary file( out of memory of one
processor), is any suggestion about this situation?

Thanks!
