These are both great observations. Please do not write the results to files, as we don't want to use Setonix's storage for these large random matrices. Other than this, I'm happy for you to address the issues in whatever way you want -- as long as you explain it in your report. Finding the limitations and how they could be solved is exactly why I made the assignment a little more open ended. You can write about these in the report, and explain some strategies you could use if you needed to scale up to larger matrices across more nodes.
