Ossim: OS-Driven Live Simulation for Cluster-Scale Full-Stack Evaluation
Yiliang Wan, Haifeng Sun, Yihan Yang +3
Cluster-scale full-stack simulation is essential for evaluating distributed software stacks and emerging hardware components before deployment. Such simulation must achieve both fu…
Columbo: Low Level End-to-End System Traces through Modular Full-System Simulation
Jakob Görgen, Vaastav Anand, Hejing Li +2
Fully understanding performance is a growing challenge when building next-generation cloud systems. Often these systems build on next-generation hardware, and evaluation in realist…
SplitSim: Large-Scale Simulations for Evaluating Network Systems Research
Hejing Li, Praneeth Balasubramanian, Marvin Meiers +2
When physical testbeds are out of reach for evaluating a networked system, we frequently turn to simulation. In today's datacenter networks, bottlenecks are rarely at the network p…
Protected Data Plane OS Using Memory Protection Keys and Lightweight Activation
Yihan Yang, Zhuobin Huang, Antoine Kaufmann +1
Increasing data center network speed coupled with application requirements for high throughput and low latencies have raised the efficiency bar for network stacks. To reduce substa…
