[OMPI users] Open MPI access the same file in parallel ?

[Jack Bryan]

Hi, 
I have a file, which is located in a system folder, which can be accessed by 
all parallel processes. 
Does Open MPI allow multi processes to access the same file at the same time ? 
For example, all processes open the file and load data from it at the same 
time. 
Any help is really appreciated. 
thanks
