[Mpi-forum] MPI load data to multiple nodes

Dear All,
I am working on a multi-computer Open MPI cluster system. 
If I put some data files in /home/mypath/folder, is it possible that all non-head nodes can access the files in the folder ? 
I need to load some data to some nodes, if all nodes can access the data, I do not need to load them to each node one by one. 
If multiple nodes access the same file to get data, is there conflict ? 
For example, 
fopen(myFile) by node 1, at the same time fopen(myFile) by node 2. 
Is it allowed to do that on MPI cluster without conflict ? 
Any help is appreciated.
