Venmo Project Fall 2019

This repo serves as reference and knowledgebase for the work completed during the Fall of 2019 by Clive Unger, Ishank Arora, and Andy Chang in the UT Computational Media Lab

Getting Started

Setting up Python 3, Jupyter Notebook, and Spark 2.4 on TACC

Running a batch job on TACC (This documentation is for Stampede2, but the same process applies for any TACC resource)

Challenges

The dataset is large enough that it can't be fit into memory, so there are many challenges that come with that. We have written up a comprehensive log of the various challenges we faced and how they were resolved. In addition, we also had various logistical challenges that we thought should be mentioned.
