Intel apresenta protótipo do Knights Corner, processador com mais de 50 núcleos

Intel apresenta protótipo do Knights Corner, processador com mais de 50 núcleos:
Recentemente, a AMD anunciou um processador com 16 núcleos (Opteron 6200) que estará disponível no mercado em breve. Quase que ao mesmo tempo, a Intel apresentou um protótipo do Knights Corner (nome provisório), um poderoso chip que poderá contar com mais de 50 núcleos.

Mas não se trata, necessariamente, de uma corrida para definir qual o processador com mais núcleos, já que ambos os chips têm focos diferentes. Enquanto que o Opteron foi desenvolvido para servidores utilizados em aplicações de cloud computing, o Knights Corner está sendo preparado para equipar supercomputadores, como o Stampede, da Universidade do Texas (Estados Unidos), que deverá entrar em operação em 2013.

O Stampede deverá trabalhar com até 10 petaflops, ou seja, poderá processar mais de 10 quatrilhões de operações de ponto flutuante por segundo. Esta capacidade praticamente o coloca em pé de igualdade com o supercomputador K, atualmente, o mais rápido do mundo.

Para tanto, chips Knights Corner responderão por 80% do processamento do supercomputador. O restante ficará a cargo dos processadores Xeon E5, que deverão estar amplamente disponíveis no mercado no segundo trimestre de 2012.


Com tecnologia de 22 nanômetros, o Knights Corner será fabricado com base na arquitetura Many Integrated Core (MIC) e terá núcleos com frequência entre 1 e 1,2 GHz. Além disso, contará com um acelerador capaz de melhorar a performance de aplicações com processamento paralelo. Sua capacidade de processamento individual está estimada em 1 teraflop.

Favigen, Favicon Generator

Favigen, Favicon Generator : " Favicons are small icons that help identify websites. They are used as a visual representation of a website both in the web browser and at many online services. The three most prominent locations of favicons are the browser’s address bar, the tabbar and the bookmarks folder. Many webmasters like to create custom favicons to add that custom identifier to their website. Favicons can be created in many image and icon editors, but also online. Favigen is a straightforward favicon generator that can turn an image into a favicon. All that it takes is to pick an image from the local hard drive first, select the dimensions of the favicon and click the submit button to make the service generate the favicon. Favigen supports several image formats, including jpg and png, and it does not seem to have size restrictions either. Available image dimensions range are 16×16, 32×32 and 64×64. The generated favicon is displayed directly on the page. A click on do...

A simple rsync script to back up your home directory

A simple rsync script to back up your home directory : " Backing up important data is obviously something we should all do. Unfortunately, it is not always easy to make it happen. We get lazy; we do not have the additional hardware for a backup server; it takes a long time and a lot of CDs to back up to optical media; we do not trust online backup services; backup schemes are difficult to set up and use — any of dozens of reasons can stand in our way. Still, we know we should be backing up our important data. Modern open source Unix-like operating systems offer a plethora of options for incredibly simple, effective backup schemes, however. If the problem is figuring out how to set one up, a simple rsync solution may be exactly what you need. The rsync utility is used to synchronize files between two systems. It does so by way of incremental copies, only copying from the source to the destination what has not already been copied there, saving time, network bandwidth, and syst...
