Re: Question CSV overwriting/interrupting lines in multithreaded operation (Nicole Ackerman)
Date: 28 Feb, 2017
From: Nicole Ackerman <Nicole Ackerman>

I wanted to briefly update with the final cause/solution, in case others find this thread for the same reason. The problem was due to a miscommunication between myself (the developer) and the users. I had enabled multithreading (MT) in the code, and had tested MT operation on standard workstations. The users were using an MPI system, which I had not enabled/integrated in the code.

The "problem" was solved by the users no longer running the code with multiple nodes. Apparently my computing knowledge was more out-of-date than I realized; they couldn't imagine setting up a parallel processing simulation *without* MPI and I hadn't fully paid attention to the different parallel computing architectures/approaches.
