Part One: Introduction
Welcome to a new series on ClusterMonkey! While the news and articles have been a bit sparse lately, it is not because the head monkey has been idle. Indeed, there is so much to write about and so little time. Another issue we ran into was how to present all the recent projects that may seem rather disparate with an easy-to-understand overriding theme. Welcome to edge computing.
Defining edge computing has become tricky because it now has a marketing buzz associated with it. Thus, like many over-hyped technology topics, it may take on several forms and have some core aspects that allow it to be treated as a "thing."
In this series, the definition of edge is going to be as specific as possible. In general, edge computing is that which does not take place in the data center or the cloud (hint: the cloud is a data center). Such a definition is too broad, however, since computing is everywhere (from cell phones to actual desktop workstations). A more precise definition of edge computing can be written as:
Data center level computing that happens outside of the physical data center or cloud.
That definition seems to eliminate many smaller forms of computing but still is a little gray in terms of "data center level computing." This category of computing usually operates 24/7 and provides a significantly higher level of performance and storage than mass-marketed personal systems.

Massive Storage Systems and Technology Conference (MSST) Announces Distinguished Keynoters and 5-Day Agenda of Notable Speakers At-scale storage in the age of AI and next gen storage to dominate 35th annual conference agenda.
Santa Clara, California, April 8, 2019 – The Massive Storage Systems and Technology Conference (MSST) today announced keynote speakers Margo Seltzer and Mark Kryder, along with a five-day agenda of invited and peer research talks and tutorials, May 20-24 in Santa Clara, California. Now on its 35th conference, MSST is the premiere large-scale storage conference that focuses on current challenges and future trends in distributed storage system technologies, drawing a diverse group of system designers and implementers, storage architects, researchers, and vendors from both industry and academia.
Water Cooling Clusters without the Plumber

When is water cooling not wet?
There is new white paper out entitled Energy Performance Evaluation of Aquila’s Aquarius Fixed Cold Plate Cooling System at NREL’s High Performance Computing Center. Before you assume this is YAWCC (Yet Another Water Cooled Cluster) you may want to consider that no water or liquids ever "touch" any processors. How then does it work? you may ask. Basically Aquila has a clever design that separates the water/processor interface with a highly efficient transfer medium. This design keeps the water contained in cooling circuit while the servers are free to be "dry servers" and require no internal plumbing. Bottom line: highly efficient water cooling with no plumbing or leaks. The Executive Summary (reprinted with permission) provides more details.
Big Data In Little Spaces: Hadoop And Spark At The Edge

Ever wonder what Edge computing is all about? Data happens and information takes work. Estimates are that by 2020, 1.7 megabytes of new data will be created every second for every person in the world. That is a lot of raw data.
Two questions come to mind. What are we going to do with it and where we going to keep it. Big Data is often described by the three Vs – Volume, Velocity, and Variability – and note not all three need apply. What is missing is the letter “U” which stands for Usability. A Data Scientist will first ask, how much of my data is usable? Data usability can take several forms and include things like quality (is it noisy, incomplete, accurate) and pertinence (is there any extraneous information that will not make a difference to my analysis). There is also the issue of timeliness. Is there a “use by” date for the analysis or might the data be needed in the future for some as of yet unknown reason. The usability component is hugely important and often determines the size of any scalable analytics solution. Usable data is not the same as raw data.

Entire Beowulf cluster to be built start to finish during Supercomputing using 3D printing.
Dallas, Texas, October 31 2018 — The Beowulf community will be featured prominently in the SC 30th Anniversary Exhibit at SC18 in Dallas November 12–15 to celebrate 30 years of SC and 25 years of the Beowulf Project. Beowulf is a methodology that uses open software to connect a local cluster of commodity-grade hardware into a single processing element. What began as a disruptive idea in 1993 has fundamentally changed the trajectory of supercomputing, and its influence has filtered down into nearly every aspect of High Performance Computing (HPC) today.
