I am a graduate Mathematics Student working on an algorithm to approximate solutions for pde using the dealii framework.
My advisor passed me some code that I cannot get to run to completion on my computer. I have no idea what might be causing this issue, or even what information to give to begin troubleshooting. I am on an M3 Max Macbook, running dealii version 9.6.0. We are approximating using the temporal parameter, and after various different timesteps, the code will throw Segmentation Fault or Bus 10 errors, or just get "stuck" at a particular calculation. Sometimes it will go as far as 64 timesteps (to completion would be 128 -- that is 256 calculations), and other times it will stay at 8 timesteps for hours. The most curious thing is that the code will not run to completion on my machine, but it will run on my advisor's. I have more ram than he does, so it should not be this way. I have tried the following: 1. Running the code, monitoring the time to completion - noting where the code stops computing and for how long. 2. After an OS upgrade, dealii stopped working properly, so I had to reinstall it completely, performance changed, but didn't necessarily improve. 3. Running the code in a clean directory each time. In reading previous posts, they say that these errors may point to a hardware issue? Please advise.
