With this project, Argonne researchers are showing that supercomputers like Mira can help drive future discoveries at CERN’s Large Hadron Collider (LHC). Running particle collision simulations on DOE leadership computing resources provides three key benefits to LHC experiments: increasing the amount of simulated data that can be produced; simulating more complex and realistic events than are currently possible; and helping to evolve LHC’s substantial code base for current and future supercomputing platforms.

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) zoomed in so that detail of the structure involved in the mixing of the gases can be seen.

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, in the 3rd District of Vienna located. The mighty, consisting of several brick buildings facility is located on a rectangular plan on a hill south of the country Strasser 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 system 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

Arsenal, with HGM (Heeresgeschichtliches Museum) from the East
The plant, 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, the old Vienna's city walls replacing, with the Rossauerstrasse 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, which, subsequently, the site management had been transferred. Under his leadership, the buildings under allocation 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 art 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 the arsenal complex and the south-east of it lying areas in the wake of district boundary changes became 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 their victory recording 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 plant 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-foot 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 system 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 2.058 inhabitants had.
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 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 system. 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 Arsenalstraße 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.

NSF MSGI research associate Arthur Mills and his mentor Wu Zhang outside of the JOULE supercomputer at NETL in Morgantown, WV. Arthur is studying Description of 3D Configuration. This project develops mathematics description of objects. Equations, and Matlab code will be needed to construct image of object in 3D space. There are several such problems in NETL’s research challenge list. The researcher of this project will be asked to work on one or more of them based on their own interests and background. One group of problems comes from the need to supply 3D printer an algorithm and/code with which an object can be manufactured through 3D printing. One of the objects would be a screw, and the other would be a hollow circular tube with arms at three different locations with each orientated differently around the tube. The other group of problem is represented by the image of a long rod in a curved tube. This is a simulation of the bending status of drill string in directional well, as commonly occurred in drilling an oil and gas well. The validation of the mathematic description of the object is expected to be conducted by providing 3D imaging of the objects with a series of cross section images staking over one and another. If time allow, the objects will be made to perform certain motion. For example, the motion can be rotating the screw or moving the rod downward simulating the drilling progress.

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 el CERN, situado entre Francia y Suiza, hay dos experimentos de propósito general que utilizan el acelerador de partículas LHC (o Gran Colisionador de Hadrones). Uno de estos experimentos es el CMS (o Solenoide Compacto de Muones) y sus objetivos son descubrir el Bosón de Higgs (bastante escurridizo), buscar evidencias de la supersimetría, estudiar las colisiones de iones pesados y explorar la materia a nivel de los TeV. El funcionamiento se resume en introducir un haz de partículas cargadas en un tubo circular y acelerarlas mediante el uso de potentes imanes, hasta que se hacen colisionar con otras partículas en el interior de un detector como el de la imagen. Mediante calorímetros ultrasensibles se detectan las trayectorias y energías de las partículas resultantes de los choques, se recogen los datos y, a través de los cables azules, se envían a potentes ordenadores en los que se analizan y se proponen modelos que expliquen las colisiones. Estos experimentos sirven para avalar o refutar las teorías que se van proponiendo acerca de la constitución de la materia a nivel subatómico, algo que escapa a mi modesto conocimiento de bioquímico. Quien quiera saber más sobre el tema, puede consultar:

The CMS (Compact Muon Solenoid) experiment is one of the two large general-purpose particle detectors built on the LHC (Large Hadron Collider) at CERN (between Switzerland and France). Its supposed goals are exploring matter physics at the TeV scale, discovering the Higgs Boson, studying aspects of heavy ions collisions and looking for evidence of supersimmetry. How does it work? A charged particles beam is introduced in a circular pipe and they are accelerated with very powerful magnets, until they are forced to collide against other particles within this huge detector. By means of ultrasensible calorimeters, the resulting particles are tracked and their energies measured. Through the blue wires, the data are sent to supercomputers which analyse and check if the proposed models explain the collisions and resulting particles, which later is used to endorse or refute the theories about the constitution of matter at subatomic levels. As far as my knowledge of Fundamental Physics is limited to a biochemist's, if someone wants to know how it works and which are the different components of the detector, better go to:

A NASA computer model simulates the astonishing track and forceful winds of Hurricane Sandy.
Hurricane Sandy pummeled the East Coast late in 2012’s Atlantic hurricane season, causing 159 deaths and $70 billion in damages. Days before landfall, forecasts of its trajectory were still being made. Some computer models showed that a trough in the jet stream would kick the monster storm away from land and out to sea. Among the earliest to predict its true course was NASA’s GEOS-5 global atmosphere model. The model works by dividing Earth’s atmosphere into a virtual grid of stacked boxes. A supercomputer then solves mathematical equations inside each box to create a weather forecast predicting Sandy’s structure, path and other traits. The NASA model not only produced an accurate track of Sandy, but also captured fine-scale details of the storm’s changing intensity and winds. Watch the video to see it for yourself.

One of the first Cray supercomputers to achieve 1 petaflops (1,000,000,000,000,000 operations per second)
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.

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.

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.

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.
This fine example of mid-1970s computing muscle is on display in the Science Museum in London. The Cray-1 was launched in 1976, and at the time was one of the world's most powerful computers.
From what I recall, the Nokia N95 I took this photo with (and uploaded it to Flickr from), packs more computing power than this baby, but the Cray just looks so cool (and you can't sit on an N95, or if you did, you'd probably break something).
Does someone build a PC case that looks like this?

1980–1999: Partners in Science
President George H. W. Bush visits ORNL in 1992 to witness the signing of a cooperative research and development agreement between the lab and the Coors Technical Ceramics Company that aims to improve engines of the future.
As the Cold War cools down and America sifts through the implications of the Three Mile Island accident, ORNL strengthens its dedication to nuclear nonproliferation, nuclear safety, and security efforts around the world. The laboratory also focuses on transforming scientific discoveries into useful technologies that can be deployed in the marketplace. Partnerships between the national laboratories and private industry enable rapid strides in solving transportation and building efficiency problems, and successive generations of ever-more powerful supercomputers accelerate research and development.
