			<content:encoded><![CDATA[<p>Não deu pra postar antes, mas agora que já até palestrei e estou com tempo livre posso falar um pouco melhor. Ontem eu palestrei no 11o Fórum Internacional de Software Livre, ou FISL 2010. Minha palestra teve como título <strong>&#8220;﻿﻿Programação Multicore: Como sobreviver a esta revolução usando o Pinguim?&#8221;</strong> e tanto os slides quanto os códigos-fonte estão disponíveis para download em [1] e [2], respectivamente.</p>
<p>Fora o nervosismo e calorão que senti, mesmo com a temperatura estando por volta do 10 graus Celsius Porto Alegre, e que achei estranho pois já fiz apresentações para um público mais numeroso, a palestra foi muito legal (pelo menos no meu ponto de vista <img src='http://blog.pvital.org/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' />  ). O único problema que tive foi com o tempo, pois com os 40 minutos de apresentação estipulados não consegui mostrar na prática os fontes de MPI, PThreads, OpenMP e X10 que havia preparado para a sessão.</p>

			<content:encoded><![CDATA[<p>During this year, I worked in the Linux version of the IBM ServerGuide Scripting Toolkit (SGSTK), one of  the tools from <a title="IBM System x ToolsCenter" href="http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=TOOL-CENTER&amp;brandind=5000008" target="_blank">IBM System x® ToolsCenter</a>. The SGSTK is a collection of system-configuration tools and installation scripts that you can use to deploy software to your IBM eServer or xSeries server in a repeatable, predictable manner.</p>
<p>After two older releases this year, today we release the version 2.00 of  the SGSTK. This version is very special for the development team, because we worked hard to develop a new framework, more stable, robust and (why not?) beauty, than the older one.  You can download it from <a title="IBM ServerGuide Scripting Toolkit" href="http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=SERV-TOOLKIT&amp;brandind=5000008" target="_blank">here</a>.</p>

			<content:encoded><![CDATA[<p>Novembro chegou, e com ele a <a title="SC08" href="http://sc08.supercomputing.org/" target="_blank">SC Conference</a>, a maior conferência internacional para computação de alto desempenho (HPC), redes, storage e análise. Como é de costume nessa conferência, mais uma lista dos 500 mais poderosos supercomputadores, a <a title="November's 2008 TOP500 list" href="http://www.top500.org/lists/2008/11" target="_blank">TOP500</a>, foi lançada e nela mais uma vez o Roadrunner da IBM ficou em primeiro lugar.</p>
<p>O interessante dessa nova lista foram as outras posições, entre a segunda e a décima, dessa vez dominada pela <a title="Cray Inc." href="www.cray.com" target="_blank">Cray Inc</a>. Diferentemente da última lista (comentada por mim <a title="~pvital blog" href="http://blog.pvital.org/2008/06/19/top500-e-o-uso-do-linux/" target="_blank">aqui</a>), onde a <a title="IBM" href="http://www.ibm.com" target="_blank">IBM</a> tinha cinco dos Top10, dessa vez a Cray Inc. tem quatro delas: #2 &#8211; Jaguar XT5, #7 &#8211; Franklin, #8 Jaguar XT4 e #9 &#8211; Red Storm. As outras posições foram: #3 &#8211; Pleiades (<a title="SGI" href="http://www.sgi.com" target="_blank">SGI</a>), #4 &#8211; BlueGene/L (IBM), #5 &#8211; BlueGene/P (IBM), #6 &#8211; Ranger (<a title="Sun Microsystems" href="http://www.sun.com" target="_blank">Sun Microsystems</a>) e #10 &#8211; Dawning 5000A (<a title="Dawning" href="http://www.dawning.com.cn/en/index.asp" target="_blank">Dawning</a>).</p>
<p>O Brasil tem dois representantes nesta lista. O melhor colocado é um Dell PowerEdge Cluster, chamado de Netuno, do <a title="NCE-UFRJ" href="http://www.nce.ufrj.br/" target="_blank">Núcleo de Computação Eletrônica</a> da UFRJ que ficou na posição <a title="Netuno" href="http://www.top500.org/system/9259" target="_blank">#306</a>, e o seguinte, que ficou na posição <a title="PGS" href="http://www.top500.org/system/details/9725" target="_blank">#363</a>, é um IBM xSeries x3550 Cluster Xeon quad core HT da PGS.</p>
<p>Outro dado interessante é o contínuo crescimento do número de sistemas utilizando Linux. Nesta lista, foram 439 sistemas (acrescimo de 12 com relação a lista anterior) com sistema operacional da família Linux. É o pinguin dominando o mercado <img src='http://blog.pvital.org/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>After 46 days away, I returned yesterday to work. On August, 2nd I broke my left arm playing soccer at the IBM Cup and I could not work.</p>
<p>During this time offline, I was moved to the <a title="Cell IDE alphaworksk page" href="http://alphaworks.ibm.com/tech/cellide" target="_blank">Cell IDE</a> project. Cell IDE is a set of Eclipse plug-ins that integrate the Cell Broadband Engine tool chain and enable rapid building of Cell Broadband Engine applications, and it is included in the <a title="IBM SDK for Multicore Acceleration" href="http://www-128.ibm.com/developerworks/power/cell/index.html" target="_blank">IBM SDK for Multicore Acceleration</a>.</p>
<p>This change is good for me, once in my master&#8217;s project I&#8217;m working with transactional memories applied to the Cell processor and other multicore processors. I guess this new project gives me a lot of opportunity and changes to grow up.</p>

			<content:encoded><![CDATA[<p>Today a new <a title="Top 500 (june/2008)" href="http://www.top500.org/lists/2008/06" target="_blank">list</a> of the 500 world&#8217;s most powerful supercomputers (<a title="Top 500 Supercomputers Site" href="http://www.top500.org" target="_blank">Top500</a>) was presented at the <a title="23rd ISC" href="http://www.supercomp.de/isc08/content/" target="_blank">23rd International Supercomputing Conference</a> in <a title="Dresden, Germany" href="http://en.wikipedia.org/wiki/Dresden" target="_blank">Dresden, Germany</a>. This list has a particular issue: the petaflops barrier was broken. The responsible by this fact? <a title="Roadrunner's Top500 page" href="http://www.top500.org/system/9485" target="_blank">Roadrunner</a>, the most powerful supercomputer of the world.</p>
<p><a title="Roadrunner" href="http://www.lanl.gov/news/index.php/fuseaction/nb.story/story_id/13552/nb_date/2008-06-09" target="_blank">Roadrunner</a>, named after the New Mexico state bird, cost about US $100 million, and was designed and build by IBM at <a title="Los Alamos National Laboratory" href="http://www.lanl.gov/" target="_blank">Los Alamos National Laboratory</a> to the <a title="DOE's NNSA" href="http://nnsa.energy.gov/" target="_blank">Department of Energy’s National Nuclear Security Administration</a>.  It <span><span>is the world’s first hybrid 	supercomputer, designed to <a title="Cell BE" href="http://www.research.ibm.com/cell/" target="_blank">Cell Broadband Engine</a>® works with the </span></span><span><span><a title="AMD Opteron processor" href="http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8825,00.html" target="_blank">Opteron</a>®</span></span><span><span> processors from 	<a title="AMD  " href="http://www.amd.com" target="_blank">AMD</a>. A few numbers of Roadrunner:</span></span></p>
<ul>
<li><span><span>connects 6,562 dual-core AMD Opteron® chips as well as 12,240 Cell 	chips (on IBM Model QS22 blade servers),</span></span></li>
<li><span><span>has 98 	terabytes of memory,<br />
</span></span></li>
<li><span><span>is housed in 278 refrigerator-sized, IBM 	BladeCenter® racks occupying 5,200 square feet,</span></span></li>
<li><span><span>has 10,000 connections 	– both Infiniband and Gigabit Ethernet &#8212; that required 55 miles of fiber 	optic cable,</span></span></li>
<li><span><span>weighs 500,000 lbs. </span></span></li>
</ul>
<p><span><span>But other important thing about Roadrunner is its operating system: a Linux version from <a title="Red Hat Linux" href="http://www.redhat.com" target="_blank">Red Hat</a>. All the Top10 most powerful supercomputers have Linux. Four of them have only Linux running: #1 Roadrunner (<a title="IBM" href="http://www.ibm.com" target="_blank">IBM</a>), #4 Ranger (<a title="Sun Microsystems" href="http://www.sun.com" target="_blank">Sun Microsystems</a>), </span></span><span><span>#5 Jaguar (<a title="Cray Inc." href="http://www.cray.com/" target="_blank">Cray Inc.</a>), </span></span>#7 Encanto (<a title="SGI" href="http://www.sgi.com/" target="_blank">SGI</a>), <span><span>#8 EKA (</span></span><a title="HP" href="http://www.hp.com">Hewlett-Packard</a>) and #10 Total&#8217;s SGI Altix (SGI). The rest of them have a kind of mixed system (Linux+something): #2 BlueGene/L (IBM), #3 Argonne Blue Gene/P Solution (IBM), #6 JUGENE Blue Gene/P Solution (IBM) and #9 IDRIS Blue Gene/P Solution (IBM) have SLES9+CNK.</p>
<p>The number of supercomputers with Linux have increased by the years. From the 500 supercomputers of the last list, 427 have Linux and 40 have a mixed system with Linux (UNICOS/Linux, CNK/SLES 9, UNICOS/SUSE Linux and UNICOS/lc). See the official numbers <a title="OS numbers from TOP500(June/08)" href="http://www.top500.org/stats/list/31/os" target="_blank">here</a>. The first time that a supercomputer with Linux appeared in the Top500 list was on June,1998. The development of the Linux usage by the years can be visualized <a title="OS family development of Top500" href="http://www.top500.org/overtime/list/31/osfam" target="_blank">here</a>.</p>

			<content:encoded><![CDATA[<p>Hoje uma nova <a title="Top 500 (june/2008)" href="http://www.top500.org/lists/2008/06" target="_blank">lista</a> dos 500 mais poderosos supercompudores do mundo (<a title="Top 500 Supercomputers Site" href="http://www.top500.org" target="_blank">Top500</a>) foi apresentada na <a title="23rd ISC" href="http://www.supercomp.de/isc08/content/" target="_blank">23a International Supercomputing Conference</a> em <a title="Dresden, Germany" href="http://en.wikipedia.org/wiki/Dresden" target="_blank">Dresden, Alemanha</a>. Esta lista tem um tópico particular: a barreira do petaflop foi quebrada. O responsável por isso? <a title="Roadrunner's Top500 page" href="http://www.top500.org/system/9485" target="_blank">Roadrunner</a>, o supercomputador mais poderoso do mundo.</p>
<p><a title="Roadrunner" href="http://www.lanl.gov/news/index.php/fuseaction/nb.story/story_id/13552/nb_date/2008-06-09" target="_blank">Roadrunner</a>, nome de uma ave do estado do Novo Mexico nos EUA, custou cerca de 100 milhões de dólares, e foi projetado e construido pela IBM no <a title="Los Alamos National Laboratory" href="http://www.lanl.gov/" target="_blank">Laboratório Nacional Los Alamos</a> para a <a title="DOE's NNSA" href="http://nnsa.energy.gov/" target="_blank">Departamento de Energia</a>.  Ele é o primeiro supercomputador híbrido do mundo<span><span>, projetado para processador <a title="Cell BE" href="http://www.research.ibm.com/cell/" target="_blank">Cell Broadband Engine</a>® trabalhar em conjunto com o processador </span></span><span><span><a title="AMD Opteron processor" href="http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8825,00.html" target="_blank">Opteron</a>®</span></span><span><span> da	<a title="AMD  " href="http://www.amd.com" target="_blank">AMD</a>. Alguns números do Roadrunner:</span></span></p>
<ul>
<li><span><span>conecta 6562 chips dual-core AMD Opteron® bem como 12.240 chips Cell (em servidores blades IBM Modelo QS22),</span></span></li>
<li><span><span>tem 98 	terabytes de memória,<br />
</span></span></li>
<li><span><span>está em 278 IBM 	BladeCenter® racks ocupando </span></span>483.095 m²<span><span>t,</span></span></li>
<li><span><span>tem 10.000 conexões 	– ambas Infiniband e Gigabit Ethernet &#8212; que requiseram 88,5 Km de cabos de fibra óptica,</span></span></li>
<li><span><span>pesa cerca de 227 toneladas. </span></span></li>
</ul>
<p><span><span>Mas um fato interessante sobre o Roadrunner é seu sistema operacional: uma versão de Linux da <a title="Red Hat Linux" href="http://www.redhat.com" target="_blank">Red Hat</a>. Todos os Top10 supercomputadores mais poderosos usam Linux. Quatro deles tem somente Linux: #1 Roadrunner (<a title="IBM" href="http://www.ibm.com" target="_blank">IBM</a>), #4 Ranger (<a title="Sun Microsystems" href="http://www.sun.com" target="_blank">Sun Microsystems</a>), </span></span><span><span>#5 Jaguar (<a title="Cray Inc." href="http://www.cray.com/" target="_blank">Cray Inc.</a>), </span></span>#7 Encanto (<a title="SGI" href="http://www.sgi.com/" target="_blank">SGI</a>), <span><span>#8 EKA (</span></span><a title="HP" href="http://www.hp.com">Hewlett-Packard</a>) e #10 SGI Altix da Total (SGI). O resto possuem um tipo de sistema misto (Linux+alguma coisa): #2 BlueGene/L (IBM), #3 Argonne Blue Gene/P Solution (IBM), #6 JUGENE Blue Gene/P Solution (IBM) e #9 IDRIS Blue Gene/P Solution (IBM) todos com SLES9+CNK.</p>
<p>O número de supercomputadores com Linux tem crescido através dos anos. Dos 500 supercomputadores da última lista, 427 rodam Linux e 40 tem um sistema misto com Linux (UNICOS/Linux, CNK/SLES 9, UNICOS/SUSE Linux and UNICOS/lc). Veja os números oficiais <a title="OS numbers from TOP500(June/08)" href="http://www.top500.org/stats/list/31/os" target="_blank">aqui</a>. A primeira vez que um supercomputador com Linux apareceu na lista Top500 foi em Junho de 1998. O crescimento do uso de Linux através dos anos em supercomputadores pode ser visto <a title="OS family development of Top500" href="http://www.top500.org/overtime/list/31/osfam" target="_blank">aqui</a>.</p>
<p><strong>Update:</strong> Curiosamente, Roadrunner é nome americano do personagem Papa-Léguas da animação <a title="Papa-Léguas e Coiote" href="http://pt.wikipedia.org/wiki/Papa-L%C3%A9guas_e_Coiote" target="_blank">Papa-Léguas e Coiote</a>. Os nomes dos personagens da animação são baseados em nome de animais reais nativos dos desertos do sudoeste americano, o galo-corredor e o coiote.</p>

			<content:encoded><![CDATA[<p>Antes de mais nada, gostaria  de dizer que a <a href="http://www.google.com/search?q=define:+procrastinar&amp;hl=en&amp;oi=definel&amp;defl=pt" title="Definição de procrastinar">procrastinação</a> esta tomando conta de minha vida, tanto que, o <a href="http://www.ibm.com/developerworks/blogs/page/ctaurion?entry=combater_a_dengue" title="Conbater a Dengue!" target="_blank">Cezar Taurion</a> criou um post antes de mim sobre o mesmo assunto e dica de tecnologia que vou dar, só por causa dela <img src='http://blog.pvital.org/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' /> </p>
<p>Agora o assunto real. Nas últimas semana a Dengue tomou conta do Rio de Janeiro. De quem é a culpa? Bem, vou citar aquele velho ditado &#8220;Não sei, não quero saber e tenho raiva de quem sabe!&#8221;. O que eu sei é que qualquer pessoa que tenha um computador e acesso a internet pode fazer a sua parte e ajudar a, de certa forma, combater a dengue.</p>
<p>Ok, daí você vai me perguntar: &#8220;Como isso é possível se não moro no Rio?&#8221; Daí eu te respondo: &#8220;Doando processamento de sua máquina para a pesquisa <em><a href="http://www.utmb.edu/discoveringdenguedrugs%2Dtogether/" title="Discovering Dengue Drugs-Together project" target="_blank">Discovering Dengue Drugs-Together</a></em>.&#8221; O projeto tem como principal objetivo de encontrar drogas capazes de combater a Dengue, Hepatite C, Febre Amarela e todas as demais doenças causadas pelo vírus da família <em>Flaviviridae, </em>utilizando uma tecnologia conhecida como computação voluntária ou filantrópica (<em>voluteer computing</em>).</p>
<p>Projetos que necessitem de alto poder de processamento computacional usam a computação voluntária, que utliza conceitos de <a href="http://pt.wikipedia.org/wiki/Computa%C3%A7%C3%A3o_em_grade" title="Computação em grade" target="_blank">computação em grade</a> (<em>grid computing</em>), para dividir o processamento em partes menores e distribuí-los para serem processadas em diversos computadores ao redor do mundo quando estão ociosos. O projeto <em>Discovering Dengue Drugs-Together</em> faz parte da iniciativa <em><a href="http://www.worldcommunitygrid.org/index.jsp" title="World Community Grid" target="_blank">World Community Grid </a></em>(WCG), que tem um forte apoio da IBM, e tem como objetivo criar a maior grade computacional para trabalhos em prol da humanidade.</p>
<p>Assim, para fazer a sua parte, acesse o site do WCG, cadastra-se, faça o download da aplicação cliente (existem versões para Linux, MacOS e Windows) e execute-o. No momento do cadastro é possível escolher os projetos no qual você deseja participar: selecione a opção <em>Discovering Dengue Drugs-Together. </em>Para aqules que já possuem o <a href="http://boinc.berkeley.edu/" title="BOINC" target="_blank">BOINC</a> (aplicativo que o WCG utiliza) instalado na máquina, mas não são cadastrados no WCG, basta se registrar (selecionando os projetos) e adicionar o projeto WCG no seu aplicativo.</p>
<p>Para aqueles que possuem Linux, o website Linux.com lançou dia 31 de Março uma matéria chamada &#8220;<em><a href="http://www.linux.com/feature/130467" title="linux.com" target="_blank">Using your Linux box for volunteer computing</a></em>&#8221; (Usando sua máquina Linux para computação voluntária) escrito por Peter Enselei, onde são apresentados vários projetos que utilizam computação voluntária para Linux além do BOINC &#8211; esse artigo foi o estopim da minha idéia de escrever este post.</p>
<p>Bem! A dica foi dada e você pode fazer parte em prol da humanidade.</p>

			<content:encoded><![CDATA[<p>A little post that I posted in my IBM internal blog.</p>
<p>Ok, everyone has heard about the <a href="http://www.top500.org/">Top500</a> list, a twice year list of the sites operating the 500 most powerful supercomputers systems of the world. The first list is commonly announced during the <a href="http://www.supercomp.de/">International SuperComputing Conference &#8211; ISC</a> (June), and the second during the <a href="http://www.supercomputing.org/">International Conference for High Performance Computing, Networking, Storage, and Analysis &#8211; SC</a> (November).</p>
<p>The first position of the last list (released on November 12th, 2007) is the <a href="http://www.top500.org/system/8968">BlueGene/L System</a>, a joint development of IBM and the Department of Energy&#8217;s (DOE) National Nuclear Security Administration (NNSA) that was installed at DOE&#8217;s <a href="http://www.top500.org/site/2556">Lawrence Livermore National Laboratory</a> in Livermore, Calif. The No. 2 is from IBM too, a <a href="http://www.top500.org/2007_overview_recent_supercomputers/ibm_bluegene_l_p">BlueGene/P</a> system installed in Germany at the <a href="http://www.top500.org/site/649">Forschungszentrum Juelich (FZJ).</a> From the Top10, there are four IBM&#8217;s systems, and 46.6% of the 500 systems are IBM.</p>
<p>And about the <a href="http://www.green500.org/">Green500</a> list, who&#8217;s know it? The Green500 provides a ranking of the most energy-efficient supercomputers in the world and serve as a complementary view to the Top500 list. The first list was announced on November 15th, 2007 at SC07, and we can see the rank <a href="http://www.green500.org/lists/2007/11/index.html">here</a>.</p>
<p>But why is it important to IBM? Because the numbers!! From the first until the 27th position, only the No. 6 is not from IBM. The first five systems are Blue Gene/P Solution, and from the No. 7 until the No. 27 they are eServer Blue Gene Solutions.</p>
<p>This is a clear result of the green concern that IBM is involved.</p>

			<content:encoded><![CDATA[<p>As my first post, I&#8217;d like to talk about my developerWorks article published in Sept/29/2007. The article is about how to install Linux on POWER machines using the IBM Installation Toolkit for Linux on POWER, and it was published in <a href="http://www.ibm.com/developerworks/linux/library/l-power-installation-toolkit/index.html">IBM DeveloperWorks website</a>. It was published in the &#8220;Linux&#8221;, &#8220;Power Architecture technology&#8221; and &#8220;IBM Systems&#8221; brands of the website.</p>
<p>This article is based in the last <a href="http://www14.software.ibm.com/webapp/set2/sas/f/lopdiags/installtools/home.html">IBM Installation Toolkit</a> version (2.1) that was released in Sept/25/2007. I think that it was a success, because it was translated to <a href="http://www.ibm.com/developerworks/cn/linux/l-power-installation-toolkit/index.html" target="_blank">Chinese</a> and <a href="http://www.ibm.com/developerworks/jp/linux/library/l-power-installation-toolkit/index.html">Japanese</a>.</p>
<p>I hope you like the reading and please, feel free to write comments about the article <img src='http://blog.pvital.org/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' /> </p>
