As part of the lab's new outreach initiative NERSC has started a partnership program with Oakland Technical High School's Computer Science and Technology Academy, a small academy within the larger Oakland Tech High School. On Thursday afternoon June 3rd, 12 students from Oakland Tech and their teacher Emmanuel Onyeador visited the NERSC Oakland Scientific Facility for an introduction to computational science, supercomputer architecture, and a tour of the NERSC machine room. Katie Antypas, a High Performance Computing consultant gave an overview of NERSC Center and an introduction to parallel programming explaining why science problems require such huge computers. Dave Paul, a systems engineer brought out computer nodes and parts from NERSC's older systems and demonstrated how the components have become both more dense and more power efficient as the technology has evolved over time. Each student was able to take home a piece of Seaborg, a Power3 system NERSC decommissioned a few years ago. Finally David Stewart, a network engineer, led the students on a dynamic tour of the machine room, showing not only the computational systems but lifting floor tiles to display the vast networking, cabling and piping infrastructure underneath the floor required to run a center like NERSC.

Arsenal (Vienna)
The Vienna Arsenal, object 1
(Pictures you can see by clicking on the link at the end of page!)
The Arsenal in Vienna is a former military complex in the southeast of the city, located
in the 3rd district of Vienna. The mighty, consisting of several brick buildings facility is located on a rectangular plan on a hill south of the Country Road Belt (Landstraßer Gürtel).
Meaning
The Arsenal is the most important secular assembly of Romantic Historicism in Vienna and was conducted in Italian-Medieval and Byzantine-Moorish forms. Essentially the complex is preserved in its original forms; only the former workshop buildings within the bounding, from the the outside visible wings were replaced by new constructions.
History to 1945

The complex, with a total of 31 "objects" (buildings) was built from 1849 to 1856 on the occasion of the March Revolution of 1848 and was the first building of the fortress triangle, replacing the old Vienna's city walls, with the Rossauer Barracks and the now-defunct Franz Joseph barracks at Stubenring. These buildings should not serve to deter foreign enemies from the city, but to secure state power in the event of revolutionary upheavals in Vienna. The decision to build the Arsenal, it came from the 19-year-old Emperor Franz Joseph I who on 2 December 1848 had come to the throne.
The design for the Imperial Artillery Arsenal came from General Artillery Director Vincenz Freiherr von Augustin, to which, subsequently, the site management had been transferred. Under his leadership, the buildings under assignment of sectors have been planned of the architects Carl Roesner, Antonius Pius de Riegel, August Sicard von Sicardsburg, Eduard van der Nüll, Theophil von Hansen and Ludwig Förster and built by the company of the architect Leopold Mayr.
From 1853 to 1856, Arsenal church was built by the architect Carl Roesner. The K.K. Court Weapon Museum, later K.K. Army Museum, now Museum of Military History, housed in a separate representative free-standing wing, was completed structurally in 1856, but was only in 1869 for the first time accessible.
For the construction of the Arsenal 177 million bricks were used. Construction costs totaled $ 8.5 million guilders. In the following years, there have been extensions. During the two world wars, the complex served as a weapons factory and arsenal, especially as barracks.
The record number of employees in Arsenal was reached in the First World War, with around 20,000 staffers. After 1918, the military-industrial operation with own steel mill was transformed into a public service institution with the name "Austrian Factories Arsenal". However, there were almost insoluble conversion problems in the transition to peacetime production, the product range was too great and the mismanagement considerable. The number of employees declined steadily, and the company became one of the great economic scandals of the First Republic.
By the fall of 1938, the area belonged to the 10th District Favoriten. However, as was established during the "Third Reich" the Reich District of Greater Vienna, became the arsenal complex and the south-east of it lying areas in the wake of district boundary changes parts of the 3rd District.
During the Second World War, in the Arsenal tank repair workshops of the Waffen-SS were set up. In the last two years of the war several buildings were severely damaged by bombing. During the Battle of Vienna, in the days of 7 to 9 April 1945, was the arsenal, defended by the 3rd SS Panzer Division "Totenkopf", focus of the fighting, the Red Army before its victory facing heavy losses.
History since 1945
Ruins of the object 15 after the air raids 1944
Deposits at the Arsenal Street
After heavy bomb damages during the Second World War, the buildings of the Arsenal were largely restored to their original forms.
In the southern part and in the former courtyard of the arsenal several new buildings were added, among them 1959-1963 the decoration workshops of the Federal Theatre designed by the architects Erich Boltenstern and Robert Weinlich. From 1961 to 1963, the telecommunications central office was built by the architect Fritz Pfeffer. From 1973 to 1975 were built operation and office building of the Post and Telephone Head Office for Vienna, Lower Austria and Burgenland (now Technology Centre Arsenal of Telekom Austria) with the 150-meter high radio tower in Vienna Arsenal according to the plans of architect Kurt Eckel. In the 1990s, a rehearsal stage of the Castle Theater (Burgtheater) was built according to plans by Gustav Peichl.
Also the Austrian Research and Testing Centre Arsenal, now Arsenal Research, which has made itself wordwide a celebrity by one of the largest air chambers (now moved to Floridsdorf - 21st District), was housed in the complex. A smaller part of the complex is still used by the Austrian army as a barracks. Furthermore, the Central Institute for Disinfection of the City of Vienna and the Central Chemical Laboratory of the Federal Monuments Office are housed in the arsenal. The Military History Museum uses multiple objects as depots.
In one part of the area residential buildings were erected. The Arsenal is forming an own, two census tracts encompassing census district, which according to the census in 2001 had 2.058 inhabitants.
End of 2003, the arsenal in connection with other properties of the Federal Property Society (BIG - Bundesimmobiliengesellschaft) was sold to a private investor group. Since early 2006, the lawyer of Baden (Lower Austria, not far away from Vienna) Rudolf Fries and industrialist Walter Scherb are majority owners of the 72,000 m2 historic site that they want to refurbish and according to possibility rent new. Fries also plans to enlarge the existing living space by more than a half (about 40,000 m2).
An architectural design competition, whose jury on 28 and 29 in June 2007 met, provided proposals amounting to substantial structural changes in the complex. Such designed competition winner Hohensinn a futuristic clouds clip modeled after El Lissitzky's cloud bracket, a multi-level horizontal structure on slender stilts over the old stock on the outskirts of the Swiss Garden. The realization of these plans is considered unlikely.
Some objects are since 2013 adapted for use by the Technical University of Vienna: Object 227, the so-called "Panzerhalle" will house laboratories of the Institute for Powertrains and Automotive Technology. In object 221, the "Siemens hall", laboratories of the Institute for Energy Technology and Thermodynamics as well as of the Institute for Manufacturing Technology and High Power Laser Technology are built. In object 214 is besides the Technical Testing and Research Institute (TVFA) also the second expansion stage of the "Vienna Scientific Cluster" housed, of a supercomputer, which was built jointly by the Vienna University of Technology, the University of Vienna and the University of Agricultural Sciences.
Accessibility
The arsenal was historically especially over the Landstraßer Gürtel developed. Today passes southeast in the immediate proximity the Südosttangente called motorway A23 with it connection Gürtel/Landstraßer Hauptstrasse. Southwest of the site runs the Eastern Railway, the new Vienna Central Station closes to the west of the arsenal. Two new bridges over the Eastern Railway, the Arsenal Stay Bridge and the Southern Railway bridge and an underpass as part of Ghegastraße and Alfred- Adler-Straße establish a connection to the on the other side of the railway facilities located Sonnwendviertel in the 10th District, which is being built on the former site of the freight train station Vienna South Station.
On the center side is between Arsenal and Landstraßer Gürtel the former Maria Josefa Park located, now known as Swiss Garden. Here stands at the Arsenal street the 21er Haus, a branch of the Austrian Gallery Belvedere, on the center-side edge of the Swiss Garden has the busy suburban main railway route the stop Vienna Quartier Belvedere, next to it the Wiener Linien D (tram) and 69A (bus) run.
The data-intensive computing power of the Stampede supercomputer at UT's Texas Advanced Computing Center allows scientists to accelerate research in such areas as brain tumor imaging, the treatment of cancer and DNA repair — and that’s just for starters.

Using the Titan supercomputer at the US Department of Energy’s Oak Ridge National Laboratory, a team of astrophysicists created a set of galactic wind simulations of the highest resolution ever performed. The simulations will allow researchers to gather and interpret more accurate, detailed data that explains how galactic winds affect the formation and evolution of galaxies.
Brant Robertson of the University of California, Santa Cruz, and Evan Schneider of Princeton University developed the simulation suite to better understand galactic winds—outflows of gas released by supernova explosions—which could help explain variations in their density and temperature distributions. The improved set of galactic wind simulations will be incorporated into larger cosmological simulations.
In this video, a galactic wind simulation depicts the galactic disk comprised of interstellar gas and stars (red) and the outflows (blue) captured using Titan and the Cholla astrophysics code.

Deep in space, giant galaxy clusters filled with vast clouds of hot, X-ray producing gas are assembled through supersonic collisions over billions of years. In order to better understand these astrophysical phenomena, called galaxy cluster mergers, scientists visualize them using supercomputers—resulting in this beautiful image.
--more details--
Dark matter makes up the majority of the cluster material, up to 90% by mass, and the gravitational force of the dark matter dominates the physics of the merger. Most of the ordinary matter is in the form of a hot, diffuse plasma known as the intra-cluster medium. These gases interact directly, unlike the dark matter particles, whose motion is thought to be collisionless. However the mixing of the gas is completely driven by the violent orbital motion of the dark matter cores. Shown here are volume renderings of the gases (in blue and yellow) and trajectories of some of the dark matter particles from each cluster.

The light from early galaxies had a dramatic impact on the gases filling the universe. The stars in these galaxies gave off radiation that ionized the gas (stripping away an electron). This is a supercomputer simulation of this event, called the “epoch of reionization.” The coral-like blobs are created by comparing the gas density in this simulation to one without the light from early stars.
MORE DETAILS »
This visualization highlights the spatial structure of the effect of the light from early galaxies, by comparing the density field from two simulations: one with a self-consistent radiation field (radiative), and one without (non-radiative). The coral-like blobs are regions where light has radiated out, heating the gas, and raising the pressure. The red regions show where the density is much higher in the radiative simulation, while the yellow regions are where the non-radiative has more density. This is the first known visualization of a process known as Jeans smoothing.

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.
en.wikipedia.org/wiki/Retrocomputing
Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.
Argonne director Peter Littlewood speaks alongside members of Congress and industry at the announcement of DOE's award of $200 million to Argonne in order to build the world's next supercomputer, Aurora.
"By investing in large computing resources like Aurora, the scientific community actually ends up realizing large saving in experiments - the ability to make virtual models means researchers have fewer costly experimental runs and can produce and analyze new data and new conclusion much more cheaply and quickly."

2018: Summit Supercomputer
When installation is complete, Summit will feature IBM's POWER9 processors, NVIDIA Volta GPUs, and NVLink connections.
ORNL will soon launch Summit, the next leap in leadership-class computing systems for open science. Compared with Titan, the lab's current supercomputer, Summit will move data 5 to 10 times faster, store 8 times more data, and perform many more calculations simultaneously. Researchers who have been using supercomputers will be able to add much more complexity to their codes, which will produce models and simulations with much greater resolution and higher fidelity for improved research output.

A Dell Inspiron 9300 showing a Cray 2 supercomputer (by Cray Research, Inc). Like the earlier photo - Old and New Monitor Setup - this photo is of a computer showing a photo of a computer.
In this case, though, it isn't of an earlier version of itself . . . just of another computer.
Chose the Cray, as I worked for them and always felt the Cray 2 was an awesome computer! After all how many computers are there where one could have gold fish swimming inside the computer. Of course, it would end real quick after a fish touched one of the boards and I'm sure the fish food and droppings wouldn't go over, either. Yet the idea was cool . . . have visitors walk into a company and see a computer with its boards submerged in fluid along with fish swimming through it.
As I understood it come of the guys in Chippewa Falls did actually put fish inside to prove it could work, but the fish touched the boards and . .
My manager sent me for a tour of the Chippewa Falls facility and to do a presentation. During the tour I got to see a rat put into the fluid, it walked around, even played, and be very alive (wet, but alive) after draining the fluid from his lungs.

Flow simulations of thousands of particles on the Argonne Leadership Computing Facility’s Blue Gene/P supercomputer are enabling new insights into how to measure and control flow properties of large-particle dense suspensions like concrete that cannot currently be accurately measured in industrial settings. A better understanding of these properties will help ensure the optimum performance of concrete and eliminate cost overruns.
