Embedded AI Systems

• RT-TAS (EMSOFT'19, TECS'19) Vision systems co-schedules integrated CPUs and GPU by capturing platform’s thermal coupling; Chip overheating is mitigated by 6-12ºC
• RT-TRM (EMSOFT'18, TCAD'18) Capturing ambient temperature and optimizing power budget/resource utilization of control tasks; resource utilization is improved by 18.2%
• eTEC (ISLPED'17) Co-optimizing system power and cooling power of thermoelectric cooler; reducing performance loss from 19.2% to 1.8% for mobile apps

Cyber-Physical Systems and IoTs

• BPM (MobiSys'20) Enabling mobile devices to predict usable battery power and regulate peak power consumption to avoid unexpected shutoff; operation time is extended by 2.03×
• BaT (UbiComp'20, IMWUT'20) pervasively provides ambient temperature estimation using phone batteries
• Battery Scheduling (RTSS'16, TPDS'20) co-scheduling multiple power-supply (battery, ultra-capacitance) and multiple power-demand operations; performance improves by 33%
• EA-SoC (ICCPS'19) capturing real-time environment to estimate battery state-of-charge (SoC); reducing the end-of-discharge SoC from 40% to 3%.

Resource Disaggregation

• Resilient Memory (arXiv'19) resilience mechanism for common memory pooling solutions handle remote failures, evictions, corruptions; improve app latency by 64×
• Infiniswap (NSDI'17) Unifying cluster’s memory via RDMA with decentralized architecture to improve throughputs of big data applications 15× and latencies 61×
