Grad students are required to review a recent paper.
Pick a paper published in a recent (i.e. in the last ~5 years) reputable conference (e.g. PLDI, CC, CGO) or journal (e.g. ACM TACO).
The paper should be about compilers (i.e. programming language implementation, program analysis, program transformation, etc.).
Send the paper link to the instructor for approval.
Reading papers that cite the picked paper is a smart trick to quickly see what other researchers think about this paper.
