PPMC PR After cleaning up a few things based on the review this PR (#300) is merged! Hack Session I enabled a handful of checks, including some of the naming checks, in PR #309. With Helena’s he...

Cholla Profiling I wanted to start profiling Cholla so I got HPCToolkit and Omniperf running with Cholla. HPCToolkit showed which kernels are eating up time and Omniperf should help me optimize th...

Platform for Advanced Scientific Computing (PASC) Conference I spent most of the week remotely attending PASC. It was really interesting and got me connected to the US-RSE group. Optimize Charact...

Paper Writing This week I finished the shock tube figures, or at least the minimum viable product version of them. After that I spent a day writing up the sections on the linear wave convergence a...

The last two weeks have been a bit of a grab bag of random tasks but let’s start with the biggest one. MHD Code Paper In group meeting we discussed Chamba et al. 2022 and Knapen et al. 2023 which...

Linear Wave Initial Conditions I spent quite awhile this week trying to debug the linear wave initial conditions to get rid of the oscillation to no avail. Since the initialization from the vector...

Committee Meeting In the last two weeks I’ve had my committee meeting and been working on a variety of tasks. My committee meeting went and and per my committee’s suggestion I’ve started the early...

PPM Debugging I think I found the issue in PPM that I was having last week. One of the variables in the characteristic projection was defaulting to zero instead of 1. This also looks like it might...

MHD Piecewise Parabolic Reconstruction (PPMC) I set this aside for most of the week but got back to it Friday. I replaced the current PPMC algorithm with the one that Athena++ uses and it seems to...

MHD Piecewise Parabolic Reconstruction (PPMC) I’m still stuck on the oscillation in the Brio & Wu shock tube. It seems like it might be an issue with the method/limiters not working for MHD ra...
