SLOFetch: Compressed-Hierarchical Instruction Prefetching for Cloud Microservices
Zerui Bao, Di Zhu, Liu Jiang +3
Large-scale networked services rely on deep soft-ware stacks and microservice orchestration, which increase instruction footprints and create frontend stalls that inflate tail late…
Thermodynamics of majority-logic decoding in information erasure
Shiqi Sheng, Tim Herpich, Giovanni Diana +1
We investigate the performance of majority-logic decoding in both reversible and finite-time information erasure processes performed on macroscopic bits that contain microscopi…
Hidden symmetries and nonlinear constitutive relations for tight-coupling heat engines
Shiqi Sheng, Z. C. Tu
Typical heat engines exhibit a kind of homotypy: The heat exchanges between a cyclic heat engine and its two heat reservoirs abide by the same function type; the forward and backwa…
Constitutive Relation for Nonlinear Response and Universality of Efficiency at Maximum Power for Tight-Coupling Heat Engines
Shiqi Sheng, Z. C. Tu
We present a unified perspective on nonequilibrium heat engines by generalizing nonlinear irreversible thermodynamics. For tight-coupling heat engines, a generic constitutive relat…
Coefficient of performance at maximum χ-criterion for Feynman ratchet as a refrigerator
Shiqi Sheng, Pan Yang, Z. C. Tu
The χ-criterion is defined as the product of the energy conversion efficiency and the heat absorbed per-unit-time by the working substance [de Tomás et al., Phys. Rev. E, 85 (2012)…
Weighted reciprocal of temperature, weighted thermal flux, and their applications in finite-time thermodynamics
Shiqi Sheng, Z. C. Tu
The concepts of weighted reciprocal of temperature and weighted thermal flux are proposed for a heat engine operating between two heat baths and outputting mechanical work. With th…
Universality of energy conversion efficiency for optimal tight-coupling heat engines and refrigerators
Shiqi Sheng, Z. C. Tu
A unified -criterion for heat devices (including heat engines and refrigerators) which is defined as the product of the energy conversion efficiency and the heat absorbed per un…
