“K” supercomputer builds on Top 500 fastest supercomputer rankings lead

The Japanese supercomputer ranked #1 on the Top 500 fastest supercomputers broke its own record this week by hitting 10 quadrillion calculations per second (10.51 petaflops), according to its operators, Fujitsu and Riken.

The supercomputer "K" consists of 864 racks, comprising a total of 88,128 interconnected CPUs and has a theoretical calculation speed of 11.28 petaflops, the companies said.

When the LINPACK benchmark program measured the K computer in its final configuration, the supercomputer system achieved a speed of 10.51 petaflops exceeding its previous speed of 8.162 petaflops, which had placed the system in first place on the TOP500 supercomputer list published June 2011, the companies said.

So what kind of applications is such a monster machine good for? Fujitsu and Riken listed the following:

Analyzing the behavior of nanomaterials through simulations and contributing to the early development of such next-generation semiconductor materials, particularly nanowires and carbon nanotubes, that are expected to lead to future fast-response, low-power devices.

Predicting which compounds, from among a massive number of drug candidate molecules, will prevent illnesses by binding with active regions on the proteins that cause illnesses, as a way to reduce drug development times and costs (pharmaceutical applications).

Simulating the actions of atoms and electrons in dye-sensitized solar cells to contribute to the development of solar cells with higher energy-conversion efficiency.

Simulating seismic wave propagation, strong motion, and tsunamis to predict the effects they will have on human-made structures; predicting the extent of earthquake-impact zones for disaster prevention purposes; and contributing to the design of quake-resistant structures.

Conducting high-resolution (400-m) simulations of atmospheric circulation models to provide detailed predictions of weather phenomena that elucidate localized effects, such as cloudbursts.

Riken and Fujitsu have been developing the K computer, as part of Japan's Ministry of Education, Culture, Sports, Science and Technology a High-Performance Computing Infrastructure program.

Oare sunt singurul care se gandeste ca cea mai buna utilitate a sa ar fi crack-uirea md5-urilor?

[wildchild]

Punct ochit punct lovit.

Primul lucru ce mi-a trecut prin cap in timp ce citeam a fost CUDA si dupa aceea hash cracking:))

[wildchild]

De aia in curand vom trece pe MD6 sau alte minune consumatoare de timp si operatii pentru protectie...

Din fericire, creste si puterea de calcul a procesoarelor odata cu aparitia noilor tehnologii asa ca proportia s-ar putea sa ramana stabila.

[wildchild]

Romanul daca nu are imprumuta, ca asa-i sta in fire.

Daca au putere foarte mare de calcul nu inseamna ca sunt ferite de troieni si alte aplicatii malitioase care pot sa controleze monstrul.Era o chestie tare in Fortareata Digitala; de fapt, ingineria sociala a facut ca acel cod sa fie incarcat in super-computer, din dorinta NSA de a-l sparge.

[tromfil]

Exista chei publice si chei private + semnate. Acolo e ceva mai greu si ma indoiesc ca e util un troian sau orice altceva atat timp cat ai sistem dedicat bootabil de pe cd care face decriptarea mesajelor. Nu-i SF. Ramane doar forta bruta, deci ajungem exact unde e nevoie.

Cat despre roman, nu doar el, ci si rusii, chinezii sau chiar alte natii, dar care nu atrag atentia.

da, sunt constient de ingineria sociala, dar ea este mult mai complexa decat o vedem in filme. nu, nu e referire la tine - sa fim seriosi, doar zic chestii generale pentru ca toti hacerii pronunta asta neavand tangente decat ca au citit despre.

orice sistem e nesigur, iar daca iti aloci destul timp, mai devreme sau mai tarziu el va pica, eventual datorita fortei brute.

posibil sa fim putin offtopic, dar discutia sigur e interesanta pentru unii oameni si cu legatura la supercomputere.

[wildchild]

Apropo, se zicea ca vor sa aduca la ceva facultate din Timisoara (cea de vest parca) un super computer.

Se mai stie ceva legat de subiect?

[spider]

oricat de multe calcule ar face, deocamdata nu poate sa depaseasca creierul uman, ca defapt nici un calc creat pana in prezent

........deocamdata

[l34k]

Iar eu ma gandesc la PC-urile criptate pe care le avem.

[wildchild]

De fapt, cu toata puterea lor de calcul, FBI-ul inca n-a reusit sa sparga parola la brazilianul care a folosit TrueCrypt, si nu estimeaza in viitorul apropiat vreo reusita.

[l34k]

Corect, dar nu mai e mult pana acolo.

[tromfil]

@spider: Wrong. Depinde din prisma carui fapt privesti.

@wildchild: Despre Timisoara nu stiu. Stiu ca era la Suceava unul, dar care e folosit doar de studentii de la master. Din pacate n-am gasit prin presa mare lucru, asta stiu de la profii de acolo.

@Admini: Vedeti care e faza cu diacriticile ca sterge din mesaj bucati. Cred ca din cauza la XSS ati filtrat cam multe sau altceva... unu, doi
