An initial characterization of the Emu Chick
Published in IPDPS, 2018
We explored the performance of a couple microbenchmarks on a novel machine with migratory threads, meaning the compute goes where the data is, not the other way around.

Online model swapping for architectural simulation
Published in Internation Conference on Computing Frontiers, 2021
We present a framework and initial implementation of a novel technique for accelerating architectural simulation by dynamically changing the level of fidelity of simulation components.

Multifidelity Memory System Simulation in SST
Published in International Symposium on Memory Systems, 2023
We extend our previous work on multifdelity cache simulation and create a framework for an entire multifidelity memory system.
