Titan Supercomputer

[Viking Kong]

I've just now stumbled across this on Youtube, what can anyone tell me about it, purpose, use, specs, post videos talking about such things.

All I could really find was this one.

[Morfy]

I've read that it has just been shut down a few weeks ago, power consumption seems to be the cause.

I love SuperComputers, been following them since the days of the Cray XMP :)

 

How fast?? BOOMMM  - "There are a total of 299,008 processor cores and just over 710 TB of RAM.^[27] Initially Titan used the 10 PB of storage with a transfer speed of 240 GB/s"

 

Kills my zx81... :( 

 

 

 

This will tell you everything you need - Quoted the use below. :)   http://en.wikipedia.org/wiki/Titan_(supercomputer)

 

Also this is the list of the TOP 500 most powerfully computers in the world :)  http://www.top500.org/list/2012/11/

Research projects [edit]

A VERA simulation of a light water reactor's core. This image was rendered onJaguar but the project will continue with greater detail on Titan.

Although Titan is available for use by any project, the requests for use exceeded the computing time available, so selection criteria were drawn up. In 2009, the Oak Ridge Leadership Computing Facility considered fifty applications for first use of the supercomputer, but narrowed it down to six successful "vanguard" codes chosen not only for the importance of the research, but for their ability to fully utilise the computing power of the hybrid system.^[25][43] Thirty-one codes will be run on Titan throughout 2013, typically four or five at any one time.^[31][44] The code of many projects had to be modified to suit the GPU processing of Titan, but each code was required to still be capable of running on CPU-based systems so that the projects were not solely dependent on Titan.^[43] OLCF formed the Center for Accelerated Application Readiness (CAAR) to aid researchers in modifying their code for Titan and holds developer workshops at Nvidia headquarters to educate users about the architecture, compilers and applications on Titan.^[45][46] CAAR has been working on compilers with Nvidia and code vendors to integrate directives for GPUs into their programming languages.^[45] Researchers can thus express parallelism in their code with their existing programming language, typically Fortran, C or C++, and the compiler can express it to the GPUs.^[45] Dr. Bronson Messer, a computational astrophysicist, said of the task: "...an application using Titan to the utmost must also find a way to keep the GPU busy, remembering all the while that the GPU is fast, but less flexible than the CPU."^[45] Moab Cluster Suite is used to prioritise jobs to nodes to keep utilisation high; it improved efficiency from 70% to approximately 95% in the tested software.^[47][48] Some projects found that the changes increased efficiency of their code on non-GPU machines; the performance of Denovo doubled on CPU-based machines.^[43]

The six vanguard projects to use Titan are:

• S3D, a project that models the molecular physics of combustion, aims to improve the efficiency of diesel and biofuel engines. In 2009, they produced the first fully resolved simulation of autoignitinghydrocarbon flames relevant to the efficiency of direct injection diesel engines using Jaguar.^[43]
• WL-LSMS simulates the interactions between electrons and atoms in magnetic materials at temperatures other than absolute zero. An earlier version of the code was the first to perform at greater than one petaFLOPS on Jaguar.^[43]
• Denovo simulates nuclear reactions with the aim of improving the efficiency and reducing the waste of nuclear reactors.^[25] The performance of Denovo on conventional CPU-based machines doubled after the tweaks for Titan and performs 3.5 faster on Titan than it did on Jaguar.^[43][49]
• Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is a molecular dynamics code that simulates particles across a range of scales, from quantum to relativistic, to improve materials science with potential applications in semi-conductor, biomolecule and polymer development.^[50]
• CAM-SE is a combination of two codes: Community Atmosphere Model, a global atmosphere model, and High Order Method Modeling Environment, a code that solves fluid and thermodynamic equations. CAM-SE will allow greater accuracy in climate simulations.^[43]
• Non-Equilibrium Radiation Diffusion (NRDF) plots non-charged particles through supernovae with potential applications in laser fusion, fluid dynamics, medical imaging, nuclear reactors, energy storage and combustion.^[43]

The amount of code alteration required to run on the GPUs varies by project. According to Dr. Messer of the NRDF project, only a small percentage of his code is for the GPUs because the calculations are relatively simple but processed repeatedly and in parallel.^[51] NRDF is written in CUDA Fortran, a version of normal Fortran with CUDA extensions for the GPUs.^[51] Dr. Messer's research requires hundreds of partial differential equations to track the energy, angle, angle of scatter and type of each neutrino modeled in a star going supernova, resulting in millions of individual equations.^[52] The code was named Chimera after the mythological creature because it has three "heads": the first simulates the hydrodynamics of stellar material, the second simulates radiation transport and the third simulates nuclear burning.^[52] The third "head" is the first to run on the GPUs as the nuclear burning can most easily be simulated by GPU architecture although the other aspects of the code will be modified in time.^[52] On Jaguar, the project models 14 or 15 nuclear species but Dr. Messer anticipates up to 200 species could be simulated, allowing far greater precision when comparing the simulation to empirical observation.^[52]

VERA is a light water reactor simulation written at the Consortium for Advanced Simulation of Light Water Reactors (CASL) on Jaguar. VERA allows engineers to monitor the performance and status of any part of a reactor core throughout the lifetime of the reactor to identify points of interest.^[53] Although not one of the first six projects, VERA will be run on Titan having been optimised with assistance from CAAR and tested on TitanDev. Computer scientist Tom Evans found that the adaption to Titan's hybrid architecture was of greater difficulty than between previous CPU based supercomputers. Despite this, he aims to simulate an entire reactor fuel cycle, an eighteen to thirty-six month process, in one week on Titan.^[53]"

It's Whalers folding rig ;)

[jugster42]

I better folding on this would be epic :) :)

[Glenwing]

It IS folding :)  Doing computations for goodwill projects / advancement... Not protein folding specifically but the same general idea...

[XiaoPigs]

It's Whalers folding rig ;)

Your DP freaks me the f*ck out :(

 

Anyways, imagine this machine folding for the LTT folding team. We would could just sit here and let it rack up the scores for us haha.

 

Thanks for sharing!

[tabuburn]

With it, you could do Folding, Boinc, and Bitcoin mining all at the same time and still kick ass.

[heineygoat]

Gaming on this.

[tabuburn]

Gaming on this.

With that much horsepower under the hood, you could have your whole neighborhood game on it and still have maxxed out settings.  :lol:

[mrthuvi]

Gaming on this.

 

J: A quantum computer compared to an ordinary computer is like the sun compared to a charcoal drawing of the sun

S: Supposedly the answer will come before you even put the question in.

A: But will it run Crysis?

S: No

J: No

 

I'm pretty sure those supercomputer literally can't run Crysis since they don't use windows.  :lol:

[heineygoat]

I'm pretty sure those supercomputer literally can't run Crysis since they don't use windows.  :lol:

 HA! So, million dollar super computers actually don't meet the minimum system requirements to run Crysis.

[tabuburn]

Technically, you can have it simulate Windows in order for you to game on it.

i would hack it then mine bitcoins with it for like 3 hours. i would make so much cash.

[tabuburn]

Why hack it for bitcoins? Use it to hack the US Federal Reserve or US Treasury Department. Insta-$$$.

[joelthezombie15]

this is so boss i would play minesweeper so hardcore ;)

[tabuburn]

this is so boss i would play minesweeper so hardcore ;)

I wonder how hard a game of chess would be if all that horsepower powered the AI.

[ShiverMePenguins]

Why hack it for bitcoins? Use it to hack the US Federal Reserve or US Treasury Department. Insta-$$$.

LOLOL. i don't believe the reserve has any gold left. too far in the red.

 

bitcoins would be more fluid and more easily hidden. the 10$ i would get from the treasury department would be insta doorstep fbi.

[tabuburn]

Well, you could just make use US Federal Reserve to control all the banks under it and have them transfer Bill Gates money to your account.

[Torey]

Well, you could just make use US Federal Reserve to control all the banks under it and have them transfer Bill Gates money to your account.

Or you could just do something legal like sell it for the 100 million that its worth seeing that barely anyone here could even pay to have it run for a week and or one day.

 

One day of usage = 24.5 Grand in Electric Sad face

[Chevaishr]

Trinidad has like  the lowest price for electricity in the world  B)  ... wonder how much it would cost to run here  

[ShearMe]

The US Dollar is a digital currency, gold reserves do not matter, though I doubt hacking the Federal Reserve will allow you to put any number you want in your bank account.
