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.
