GPU MPI I started on getting GPU resident MPI working on the Pitt CRC cluster. So far it compiles but doesn’t run. I’m working with the CRC and other group members to get that fixed. I got access t...

MHD Debugging I spent some more time bug hunting and found that the instability only shows up when a number is not exactly expressible in binary. After discussin this with Evan they pointed out tha...

MHD Debugging My implementation of constrained transport was complicated and hard to maintain so I refactored the main loop. Primarily I just unrolled the innermost loop over the x,y,z directions. ...

MHD Debugging I spent this week comparing my code to Athena++. Throughout that process I fixed a sign error in the CT equation, turns out they should all be plusses with no minuses. I also fixed a...

Astronomical Techniques I was working a lot on the project this week. I wrote the final report, made a lot of different figures, prepared my presentation on it, and presented it. Not super exciting...

Astronomical Techniques This week in class we discussed maximum likelihood, regression, and information criteria. I was working a lot on the project this week. I implemented dimensionality reducti...

Astronomical Techniques This week in class we discussed non-parametric tests like the U test. I was working a lot on the project this week. I spent about a day reading up on MCMC techniques and ti...

Astronomical Techniques In class over the last two weeks we’ve discussed basics of machine learning and non-parametric tests. We also started our class projects in earnest. My part so far has been...

General This week I needed a break from debugging so I worked on a bunch of miscellaneous tasks that have been on the backburner for awhile; the university also had a 1 day break I also had some ex...

Astronomical Techniques More discussion of error propagation. Started planning class projects and discussed hypothesis testing. Numerical MHD Still working on bug hunting. I tested a bunch of di...
