When input data is too large to fit into memory on a single node, it's common to partition and/or store it in a collection of smaller files that can be processed in parallel. In this repository, you will find four files ss.0.0.dat, ss.0.1.dat, ss.0.2.dat, ss.0.3.dat. These files each contain one-forth of the stress-strain curve that we manipulated in Assignment 7.
Your task in this assignment is to read in the data in parallel from the files, then create an Epetra.Map and associated Epetra.Vector to store the data. Assign the Epetra.Vector to a class member variable called stress. Use the Epetra.Copy argument for robustness when instantiating the Epetra.Vector class. Once the data is stored in an Epetra.Vector is can easily be queried for its overall maximum value using the class function MaxValue().
If you would like to check to see if your solution is correct, run the following commands at the Terminal command line:
mpiexec -np 4 python test.py
