cooling codes thermal management coding for high performance interconnects
IEEE Transactions on Information Theory, 2018Co-Authors: Yeow Meng Chee, Tuvi Etzion, Han Mao Kiah, Alexander VardyAbstract:High temperatures have dramatic negative effects on interconnect performance and, hence, numerous techniques have been proposed to reduce the power consumption of on-chip buses. However, existing methods fall short of fully addressing the thermal challenges posed by high-performance interconnects. In this paper, we introduce new efficient coding schemes that make it possible to directly control the peak temperature of a bus by effectively cooling its hottest wires. This is achieved by avoiding state transitions on the hottest wires for as long as necessary until their temperature drops off. We also reduce the average power consumption by making sure that the total number of state transitions on all the wires is below a prescribed threshold. We show how each of these two features can be coded for separately or, alternatively, how both can be achieved at the same time. In addition, error-correction for the transmitted information can be provided while controlling the peak temperature and/or the average power consumption. In general, our cooling codes use $n > k$ wires to encode a given $k$ -bit bus. One of our goals herein is to determine the minimum possible number of wires $n$ needed to encode $k$ bits while satisfying any combination of the three desired properties. We provide full theoretical analysis in each case. In particular, we show that $n = k+t+1$ suffices to cool the $t$ hottest wires, and this is the best possibility. Moreover, although the proposed coding schemes make use of sophisticated tools from combinatorics, discrete geometry, linear algebra, and coding theory, the resulting encoders and decoders are fully practical. They do not require significant computational overhead and can be implemented without sacrificing a large circuit area.

International Symposium on Information Theory, 2017Co-Authors: Yeow Meng Chee, Tuvi Etzion, Han Mao Kiah, Alexander VardyAbstract:High temperatures have dramatic negative effects on interconnect performance. Numerous techniques have been proposed to reduce the power dissipation of on-chip buses but they fall short of fully addressing the thermal challenges posed by high-performance interconnects. We introduce new efficient coding schemes that directly control the peak temperature of a bus by effectively cooling its hottest wires. This is achieved by avoiding state transitions on the hottest wires for as long as necessary until their temperature drops off. At the same time, we reduce the average power consumption by ensuring that the total number of state transitions on all the wires is bounded. Our solutions call for redundancy: we use n > k wires to encode a given k-bit bus. Therefore, it is important to determine the minimum possible number of wires n needed to encode k bits while satisfying the desired properties. We provide full analysis in each case, and show that the number of additional wires required to cool the t hottest wires is negligible when k is large. Moreover, the resulting encoders and decoders are fully practical. They do not require significant computational overhead and can be implemented without sacrificing a large circuit area.

comparative analysis of inlet air cooling techniques integrated to cooled gas turbine plant
Journal of The Energy Institute, 2015Co-Authors: Alok Ku MohapatraAbstract:Abstract The current article is focused on assessing the comparison of two different means of inlet air cooling (evaporative Cooing and vapor compression cooling) integrated to a cooled gas turbine power plant. Air film cooling has been adopted as the cooling technique for gas turbine buckets. A parametric study of the effect of pressure ratio (r p,c ), compressor inlet temperature (CIT), turbine inlet temperature (TIT), inlet temperature ratio (r IT ), ambient relative humidity and ambient temperature on performance parameters of plant has been carried out. It has been observed that the integration of the inlet air cooling system to the gas turbine cycle improves the overall performance, the improvement being higher at higher ambient temperature and ambient relative humidity. At a TIT = 1700 K, r p,c = 23, RH a = 0.2 and T a = 313 K, vapor compression inlet air cooling has been observed to improve the plant specific work by 18.4% and efficiency by 4.18%, compared to 10.48% and 4.6% respectively for evaporative cooling. In geographical regions having low ambient relative humidity and low ambient temperature however, evaporative inlet air cooling should be preferred over vapor compression cooling in terms of higher plant efficiency.. The adoption of higher turbine inlet temperature has a more pronounced effect on vapor compression cooled gas turbine in terms of enhancement in plant performance parameters as compared to evaporative cooling. The work ratio increases with increase in value of r IT upto5.6 after which it decreases.
