A record of the panel discussion was not made available for publication as part of the conference proceedings. Hyperscale ethernet data centers (HEDCs) based on pure ethernet switching have come to dominate both the market and the conversation, and many think they are all that is necessary. But for many years specialized designs for HPC have survived, though these specialized designs seem increasingly relegated to fewer and fewer special cases. Some think this will only continue, and the low cost, pervasiveness, and simplicity of a single fabric will result in HEDCs being 'so good enough' that special technology for HPC will no longer be needed. Others disagree and claim that HEDCs enjoy generally uniform and static workloads that do not fit the profiles of machine learning and HPC applications. They cite technologies like PCIexpress fabrics that are infiltrating HEDCs to augment ethernet with capabilities that ethernet simply cannot provide and that are needed in both the massive HEDCs and smaller versions of same, including specialized campus DCs or clusters and those deployed at the mobile edge for mobile edge computing. In the MEC scenario, media, security, machine learning, and IOT are among the new applications driving the convergence of HPC and HEDC. The panel will debate these opposing viewpoints and will speculate on whether specialized HPC DCs and general HEDCs will converge, diverge, or continue in separate parallel worlds.","PeriodicalId":128992,"journal":{"name":"Hot Interconnects","volume":"104 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131541281","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}

Kaplow","doi":"10.1109/CONECT.2005.23","DOIUrl":"https://doi.org/10.1109/CONECT.2005.23","url":null,"abstract":"Grid computing is an attempt to make computing work like the power grid. When you run a job, you shouldn't know or care where it runs, so long as it gets done within your constraints (including security). However, in attempting to accomplish this, Grid researchers are presenting network access patterns and loads different from what has been typical of Internet traffic. MPI applications are looking for latency critical, bursty, small message traffic, some applications are producing data sets in the 100's of GBs and even Terabytes that need to be moved quickly and efficiently, or you might need remote control of earthquake shake tables and thus require constant jitter. Grid researchers are asking for finer grained control of the network, dynamic optical routes, allowing user apps (via middleware) to alter router configurations, etc. For some network operators, this sounds like their worst nightmare come true. For the network HW vendors, this presents challenges to say the least. This panel is intended to bring together Grid researchers, network operators, and network HW vendors to discuss what the Grid researchers want and why, what impact that will have on network operations, and what challenges it will bring for the future HW designs.","PeriodicalId":128992,"journal":{"name":"Hot Interconnects","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123570343","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}

The operating handle projects through an elongated wall opening in the circuit breaker housing and is movable longitudinally thereof. The shield is disposed between an arcuate interior surface of housing and an arcuate surface of an apron formed integrally with the handle. While the apron above is too short to close the wall opening for all positions of the handle, the apron in cooperation with the shield fully closes the wall opening for all positions of the handle. Latch tabs formed integrally with the shield engage a blocking formation internally of the housing to hold the shield stationary while the handle moves from its On to Trip position. In the former position ON indicia carried by the apron is viewable through an aperture in the shield through which the handle extends, and when the handle is in its Trip position the latched shield blocks the ON indicia from view. Labyrinth-type gas seals are provided adjacent the longitudinal edges of the wall aperture by longitudinally extending ribs formed integrally with the shield and extending into cooperating slots inside the housing wall.","PeriodicalId":128992,"journal":{"name":"Hot Interconnects","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131382944","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}
