With growing scientific and engineering interest, the spintronics IC community has recently achieved significant discoveries and engineering breakthroughs [1]. Most recognized is the emergence of STT-MRAM. Key findings and advances in materials, devices, and circuits have triggered extensive industry-wide R&D efforts in pursuit of an alternative memory which may not only overcome acute tradeoffs in performance and power, but also extend physical scaling limits. In parallel, various forms of logic devices and circuits based on MTJ have been demonstrated, opening a possible path for spintronic IC to expand beyond STT-MRAM.","PeriodicalId":231837,"journal":{"name":"2013 Third Berkeley Symposium on Energy Efficient Electronic Systems (E3S)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117289780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Room level Computational Fluid Dynamics (CFD) model is developed to simulate airflow rate and servers power fluctuations in a representative data center. It is found that the servers heat capacity has a significant effect on the dynamics of data centers. An order of magnitude increase is observed in the time constant associated with change in temperatures compared with models that neglects the effect of servers heat capacity. It is also found that the rack chassis heat capacity has a slight influence on temperatures rate of change, thus it can be neglected without affecting the accuracy of the results and also reducing the computational time.","PeriodicalId":231837,"journal":{"name":"2013 Third Berkeley Symposium on Energy Efficient Electronic Systems (E3S)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129596757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure effective gate control, semiconductors with ultrathin body thickness are needed. At such regime, strong quantum confinement usually comes into play; therefore, we call these ultrathin compound semiconductor membranes as quantum membranes (QMs). Compound quantum membranes heterogeneously integrated on Si substrates have been studied by us, combining the high mobility of compound semiconductors and the well-established Si technology.","PeriodicalId":231837,"journal":{"name":"2013 Third Berkeley Symposium on Energy Efficient Electronic Systems (E3S)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121283940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She has innovated circuits in the biochemical, biomechanical, and bioelectronic domains that operate robustly with highly noisy and imprecise parts and with incredibly low levels of energy. Her impressive accomplishment is largely due to the fact that she uses both analog (graded) and digital (all-or-none) circuits within her cells to sense, actuate, compute, and communicate [1]. Analog and bio-inspired approaches that mimic nature can also create ultra-energy-efficient systems: For example, we show how neural prosthetics of the future such as brain-machine interfaces for the paralyzed can be made so energy efficient [1] that they can be powered from a novel glucose fuel cell that harvests energy from bodily fluids [2]. I also discuss how a positive-feedback loop between analog circuits and cell biology may enable similar synergistic improvements in synthetic and systems biology.","PeriodicalId":231837,"journal":{"name":"2013 Third Berkeley Symposium on Energy Efficient Electronic Systems (E3S)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123777543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In times when not all of those computing capabilities are needed the task to be solved is how to distribute the load in a power-efficient manner. The research question is: How should a requested compute load be mapped to the available physical servers so that it is executed with the minimum power consumption? The requested load is measured in operations per seconds and changes over time. In this work, we assume that it is divisible which means that portions of the requested load can be freely assigned to different servers. This assumption is plausible because the load of a typical compute cloud consists of many virtual machines (VM). Our investigations are based on the SPECpower benchmark, retrieved Jan 9, 2013. SPECpower relies on Server Side Java (SSJ) for measuring power consumption of servers at different load levels running Java applications [7].","PeriodicalId":231837,"journal":{"name":"2013 Third Berkeley Symposium on Energy Efficient Electronic Systems (E3S)","volume":"331 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116359575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, graphene and transition metal dichalcogenides (TMD) exhibit remarkable properties that can be exploited for many applications.
