It seems like “linear attention” now means almost anything—as long as there’s an O(L) somewhere in the paper 🙃. Linear compute? Memory capacity? Memory traffic? Those are three different bills accelerators pay for 💰️.
My plea: show me all three: htor.inf.ethz.ch/blog/index.…

We recently published a survey on sparse DNN inference: how dense ops become sparse, what kernels exist today, which datasets people use, and some initial SpMM/SDDMM performance results.

RT appreciated! We're assembling the Artifact Evaluation Committee (AEC) for @usenix OSDI+ATC 2025.
JOIN US!
It'll be fun, useful (help understand research artifacts of accepted papers), with a manageable load (1-2 papers per AEC member based on research interests).
We are seeking members to join the Artifact Evaluation Committee for #OSDI25 & #USENIXATC25.
Help promote reproducibility, and engage with cutting-edge systems research!
Please apply by April 17th via forms.gle/187NkvkWyNtBHDsu5.
