running program on clusters, accessing data file

Hi , I have a program with parfor to run some tasks simutaniously. It works fine when using local workers but show error on clusters. It does the following. First get the list of IDs to process. Then use this list for parfor process. Inside the parfor, it does the following 1) it reads the data file for this ID 2) get updated and save it again.

I have put the data file on a shared disk and each machine can access it. But still seems it cant read in the data for some workers( I assume they are the nonlocal ones).

What cluster type are you using? What operating system? What's the error - do you know if the workers can see the correct directory but simply cannot access the files?
