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 Characteristic Reconstruction

I refactored the characteristic reconstruction so that the eigenvectors are only computed once. This and Trey White’s suggestion of adding __launch_bounds__(256) to a few kernel definitions improved performance by about 40%.


I made the plots for the MHD Blast Wave and am mostly done with the Orszag-Tang Vortex plots.
