question about using same unit number to open different files on a dual processor computer.

[gli at chem.wisc.edu]

Hi, everybody,
i use MPICH to make a parallel program on one dual-processor computer.
so there should be two processes on this computer i can use. id=0,1
i want to open different files for different id processes but using the 
same unit number, is it possible?
if yes, how i can do it?

thanks very much!!
