SIMD for Collision

In a previous post SIMD Matters I discussed the big wins I got from graph coloring to make the contact solver faster. That same approach exists in Box3D. I like to call this approach “wide SIMD”. The idea is to process multiple work units at the same time. In the contact solver this means solving four contact points at the same time. This is different from “narrow SIMD” where a 3-vector (xyz) is put into a SIMD register and then standard vector math is expressed as SIMD intrinsics.

Rethinking Legal Education in the AI Era

OverviewArtificial Intelligence is already impacting higher education and the legal profession, and the pace of change appears only to be accelerating. It is thus critical for us to use this moment to carefully reflect on how legal education should adapt. This memo describes the approach we are taking to legal education in the AI era.The University of Chicago Law School has long been committed to providing our students with the most rigorous legal education possible. This commitment manifests itself through our faculty’s dedication to teaching, our culture of challenging ideas through Socratic questioning and debate, and our grading policies that motivate students to engage with the material and that convey informative assessments of studen
