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.

Improve Windows Security By Closing Open Ports

Improve Windows Security By Closing Open Ports : " A standard Windows operating system has a number of ports open after installation. Some of these ports are needed for the system to function properly while others might not. These ports can pose a security risk as every open port on a system might be an entry point for a malicious user. A port basically allows communication to or from the device. Characteristics are a port number, an IP address and a protocol type. This article will give you the tools at hand to identify and evaluate the open ports on your Windows system to make a decision in the end whether they can or should be closed or left open. Software programs and tools that we will use: CurrPorts : Available for 32-bit and 64-bit editions of Windows. It is a port monitor that displays all open ports on a computer system. We will use it to identify the ports and the programs that are using them. Windows Task Manager: Also used to identify the programs and link some p

Diagnosing a Blue Screen of Death Error in Windows

Diagnosing a Blue Screen of Death Error in Windows : For many years now the famous Blue Screen of Death (BSoD) has been the ultimate indication that something disastrous has happened to make your computer die, but how useful is the information in the BSoD and the respective crash dump file that Windows produces? The best article I ever found explaining the BSoD in depth is here on the Microsoft website, however it’s quite technical and doesn’t discuss how to actually troubleshoot a problem. The crash dump file is just technical details of what was being held in the computer’s memory at the time of the crash, and this will include details on every driver and service that was loaded, and every piece of software that was running. The most useful pieces of information are to be found on the BSoD itself and are highlighted on the screenshot below. These are the BSoD error name, the stop error code and the name of the driver or service that has failed (this last one might not always appea

Use BGInfo to Build a Database of System Information of Your Network Computers

Use BGInfo to Build a Database of System Information of Your Network Computers : " One of the more popular tools of the Sysinternals suite among system administrators is BGInfo which tacks real-time system information to your desktop wallpaper when you first login. For obvious reasons, having information such as system memory, available hard drive space and system up time (among others) right in front of you is very convenient when you are managing several systems. A little known feature about this handy utility is the ability to have system information automatically saved to a SQL database or some other data file. With a few minutes of setup work you can easily configure BGInfo to record system information of all your network computers in a centralized storage location. You can then use this data to monitor or report on these systems however you see fit. BGInfo Setup If you are familiar with BGInfo, you can skip this section. However, if you have never used this tool, it takes ju
