You are invited to contribute to create a better world. http://www.youtube.com/watch?v=tukt3se9cz4 http://www.youtube.com/watch?v=xq3BYw4xjxE Let`s change this system that deprive us from all resources, products and services we need to live, and creates money as a barrier in a linear centralized pyramid structure. All money is created through debit. When people are in debit they submit to work. So debit is slavery. Who creates the money? Private Banks are the owners of the FED that creates money out of the thin air by just printing it. But, private Banks also create money through loans by bookkeeping. And, all money in circulation needs to be repaid to Banks with interest. So there is more debit than money. This monetarism economy is a Ponzi scheme because the bankruptcy is inevitable since the debit is higher than the money created/ in circulation. Private Banks creates money that even government needs to work. So, in this monetarism society Government`s Policy will be always dictated by Private Banks. In a monetarism economy money replaces everything is produced, but money is debt and is created by the top of the pyramid society out of the thin air. In this way, while we let the 1% create money out of the thin air, while we let this system unchecked we will remain slaves. The true so urces of wealth are We The People. Without US money and any other asset has no value. We are the true source of wealth, not gold, silver, diamond or any other thing. All process of money creation relies on a pyramid structure build to slave US. http://www.youtube.com/watch?v=ZPWH5TlbloU While private Banks keep creating money out of thin air through loans, they will remain in power. While we let the pyramid structures of our society unchecked, the 1% will keep creating wealth out of thin air. In Tahrir moment, Egypt did not change the pyramid structures in their society. They only let the Army occupy the empty spaces on the pyramid structures of their society. They should have changed how their society is organized into direct democracy, social network production of goods and services, education through webï¿½ and reshape their society from centralized pyramid structures to decentralized social network structures in sphere format. http://www.youtube.com/watch?v=Ay3NFd9DknU You are invited to build tools to improve direct democracy and several new open platforms to implement abundant production of goods and services, connecting people, knowledge, matter and energy with people`s necessity to change matter into what it is required to provide everything our society needs to live in profusion. http://www.youtube.com/watch?v=cPZI74Nk-J8 Money is only the blood of this system that has a body in pyramid shape. The top 1% creates products, services, distribute water, energy, food and all we need to live in a centralized pyramid way. They create money with loans and influence and dictate all sorts of politics. They deprived us from everything we need to live by creating barriers (law, knowledge access, false scarcity, planned obsolescence, putting us in endless debt). You are invited to bring the pyramid down. Your are invited to rebuild our society: since the production of goods, services, energy and matter to all relationship and direct democracy. You are invited to be part of the change of this pyramid society into a sphere society. http://www.youtube.com/watch?v=R8ODHwaqrWY To tax Banks with the Hobin Hood Tax transaction will turn it into an operation cost absorbed into their current cost, but it will not solve the problem that is the money creation (only private Banks and FED creates money out of the thin air) and the pyramid structures in our society made to concentrate wealth and slave people. The solution is to bring the pyramid down and reshape our society into a several local decentralized open source network self-sustainable sphere structures. http://www.youtube.com/watch?v=JAWLHA8-07c http://www.youtube.com/watch?v=qb0GsKFbAIw http://www.youtube.com/watch?v=N7ws7H00qIs Let`s bring the pyramid down. The pyramid structures has slaved our society for long time. The goal of any pyramid structure is wealth concentration through scarcity, access denial, exploitation and so onï¿½ We do not fix a thing that will bring US to the same place in the future. Einstein once said: ï¿½Insanity is doing the same thing over and over again but expecting different results.ï¿½ You are invited to suggest a better society in sphere format that mimics life and nature. In fact, nature is the ultimate open source model because its countless templates are free for anyone to use it. You are invited to create an open source decentralized system that can connect matter with peopleï¿½s need, empowerment knowledge, energy and let each person ask what they need and help local communities to organize themselves to provide each necessity. All in a new sphere system. http://en.wikipedia.org/wiki/Social_network http://www.ted.com/talks/tim_berners_lee_on_the_next_web.html Figure it out: when a child blows a soap bubble, why it takes the shape of a sphere and not the shape of a pyramid? The sphere is the most popular form in this Universe. So why did we accept the pyramid format in all human structures: social, religion, work, government? As long as the pyramid structures in our society persist, the 1% will keep slaving the 99%. http://en.wikipedia.org/wiki/File:Girl_blowing_bubbles.jpg Our goal is far larger than occupy money. You are invited to recreate all sort of human structures in this world from a pyramid structure to a sphere structure. No person, corporation or any other thing should be on top of other human being. We believe cooperation is stronger than competition. Gold can be manufactured in a nuclear reactor with low cost as long as it could be a byproduct in a reactor running to provide electricity. http://en.wikipedia.org/wiki/Synthesis_of_precious_metals Even if we nationalize The Federal Reserve it not solves the problem. Even if we end the FED but let private banks creating money through loan out of the thin air we will see the same problem again. http://occupymoney.org/ See Europe has nationalized its central banks but private banks continue creating money through loans. The owners and shareholders of the European Central Bank are the 27 member states of the EU. http://en.wikipedia.org/wiki/European_Central_Bank See England that has no limit to create money through loans. The pyramid structure was created to slave people only. http://www.ted.com/talks/yochai_benkler_on_the_new_open_source_economics.ht… You are invited to contribute to create a new social infrastructure decentralized, sustainable and Open Source to Occupy Movement. It should be collaborative to connect people with energy and knowledge to change matter to solve each peopleï¿½s need. It should be easy to replicate and adaptable to help create communities all across USA that could receive members from all world through the use of these platforms that annihilate time and space. It should be open source in format of sphere, work independently in cycles and not linear centralized pyramids. This new organization format should aim open competition of ideas and collaboration of people to spread the best practices of work, productionï¿½ and create a better world. Money is only an idea backed by confidence, backed by US. Without US money or any other asset has no value. It is time to each person create its own money backed by our own work, in decentralized way. There are people unemployed, there is knowledge available, energy, needs and matter. Let`s reorganize USA into a sphere society. We aim an Open Source Society that changes the competition of people into competition of ideas and collaboration. Everybody can contribute with knowledge, work and ideas locally and globally to solve each need for their society and to the world. It should help each community to make products and services and also do the exchange things with each other replacing money. It is not a barter system. It is a system where each person writes their needs and community organizes itself to provide all their needs in a circular and sustainable way. The best practices, products and service can be replicated and spread across nation. This open source platform has to be developed and can be inspired by best practices and ideas across the world. For instance see: http://www.innocentive.com/ http://web.mit.edu/mitpsc/whatwedo/ideas-competition/ http://globalchallenge.mit.edu/ http://www.storyofstuff.com/movies-all/story-of-broke/ http://www.altruists.org/ideas/economics/altruistic/ http://regenerosity.com/ http://www.popularmechanics.com/science/environment/green-energy/4243793 It should add the animation style to easy the idea and knowledge transmission. http://comment.rsablogs.org.uk/videos/ And look for as best content as possible. http://ocw.mit.edu/index.htm The open platform should connect the peopleï¿½s need with knowledge, energy and matter in a sustainable way to produce products and services to solve each people`s need. http://www.youtube.com/watch?v=9GorqroigqM http://www.appropedia.org/Open_Source_Ecology http://p2pfoundation.net/Open_Source_Ecology http://reprap.org/wiki/Main_Page http://makeprojects.com/Topic/Open_Source_Hardware http://www.makerbot.com/ http://www.arduino.cc/ http://labs.nortd.com/lasersaur/ http://www.willowgarage.com/ http://www.sparkfun.com/ We ask you donation of time and work.

Each small group has its problems to be solved. All they need is knowledge, energy and access to raw matter to solve its problems. There is no need of money (money is only an idea backed by confidence with some functions). There is plenty of decentralized energy from the sun: http://www.spectrolab.com/ http://www.physorg.com/news99904887.html http://www.physorg.com/news119107136.html http://www.tomsguide.com/us/Boy-Solar-Energy-Efficiency,news-12247.html We can change any matter with knowledge and energy.

Figure it out: when a child blows a soap bubble why it takes the shape of a sphere and not a pyramid? So, why did we accept pyramids in all human structures (social, work, army, religion and all sort of human organizations)? All those pyramid structures create and maintain the 1% exploiting the 99%. Why a dog doesn't see the chain around its neck? Maybe because it is too close to the eyes. But after it sees/senses the chain, it will only try to get rid of it if it is a free dog (it is not used to wear chains around its neck). All pyramid system are nothing but a structure to slave people. http://en.wikipedia.org/wiki/File:Girl_blowing_bubbles.jpg The concepts of divided linear thinking in hierarchies, priorities, competition and segments drive to a pyramid society. In order to one person climb the pyramid other has to fall. This concept is over and does not work anymore. It is crazy to maximize the idea (money) instead of the creator of the idea that is the human being. The human brain does not work like that. http://www.youtube.com/watch?v=lWMZg1YL4A4 http://www.youtube.com/watch?v=G49q6uPcwY8 It is time to change from monetarism economy to a resource based economy http://www.youtube.com/watch?v=4mkRFCtl2MI http://www.youtube.com/user/OpenSourceEconomy That new economy should aim to maximize the human quality of life in a sustainable and circular (not linear) way. http://www.youtube.com/user/storyofstuffproject The real world is not a zero sum economy. http://comment.rsablogs.org.uk/2010/06/28/rsa-animate-crisis-capitalism/ The time is now. http://www.youtube.com/watch?v=OEjWlsUfz8E We are the change. http://www.youtube.com/watch?v=nwMrXWPaPRI The key to set US free is with US and none but ourselves can free our minds. http://www.youtube.com/watch?v=o5-pg0i5Iog We are the true source of wealth and not money, gold or any other metal or rock. Do not be deceived with gold. Gold is only a metal with some peculiar chemicals properties. Even a child knows if all Earth was made of gold, we would not have the current products, development, services... we have. The value of money is backed by US only. We are the true source of wealth and we are the solution for our society. We can move from a pyramid society to a sphere society all interconnected. http://en.wikipedia.org/wiki/Social_network http://news.yahoo.com/open-source-software-heres-occupy-wall-street-co-1821… Do not expect a hero, a leader or government to help US. Each of US are the leader and we all need is to help each other. http://www.youtube.com/user/theamericandreamfilm http://www.youtube.com/watch?v=NgYE75gkzkM http://www.youtube.com/watch?v=S63Cy64p2lQ You are invited to contribute to create an open platform, a place to connect people`s needs with knowledge to change matter to solve people`s need. You are invited to contribute to make an open platform that can replace money with information. When Banks create money, the money goes back to the Bank plus interest. The bottom line is each people will make their own money through providing solutions to other people's need in a circular interconnected way. So, money goes back to the people that create it. Let`s implode the pyramid. It is the end of the linear pyramid structure. Because, if we let the pyramid society unchecked, the top of the pyramid will always print wealth out of the thin air and the 1% would continue to slave the 99%.

Zepto, MPI, and fork
by Justin M Wozniak 21 Jan '11

21 Jan '11

Hello I'm trying to use an application that uses MPI and fork. I see from the wiki and the big memory paper that this is probably not supported, but I would just like to double-check if there is a recent work-around of any kind. Also, is it worth trying to run the application using MPICH over sockets? Thanks Justin -- Justin M Wozniak

ZeptoOS 2.0 is out!
by Kamil Iskra 11 May '09

11 May '09

[Apologies if you receive multiple copies of this message] It is our pleasure to announce the immediate availability of ZeptoOS version 2.0! Many things have changed since version 1.5. Most importantly, the new version is the first public release for the IBM Blue Gene/P architecture. ZeptoOS now provides a complete software stack, covering both compute and I/O nodes. The compute nodes run ZeptoOS Compute Node Linux, which features big memory (a flat, TLB-miss free memory region) and which provides all the necessary drivers and support to run MPI applications (SMP mode only in this release). Communication between the compute nodes and I/O nodes (file I/O, IP packet forwarding) is handled by the ZeptoOS I/O Daemon (ZOID). The current release is compatible with the IBM BGP V1R3M0 software driver. For more information, and to download the release tarball, please consult the project website: http://www.zeptoos.org/ The ZeptoOS team

maximum CIOD_RDWR_BUFFER_SIZE
by Kazutomo Yoshii 31 Oct '05

31 Oct '05

Hi, Probably, we may be able to use the following formula to calculate the maximum number of CIOD_RDWR_BUFFER_SIZE. CIOD_RDWR_BUFFER_SIZE_max = (MemTotal-MemSysUsed)/(2*N) where, MemTotal : total installed memory MemSysUsed : memory used by system software N : the number of compute nodes per one I/O node. (PSET) The reason why we need (2*N) is that we have to think about the virtual mode. MemTotal is 512MByte per default( no exception?). ZeptoOS1.1 uses approx. 60MB which includes pvfs2, sshd, etc memory usage. On the most of BGL systems, PSET is 32 and CIOD_RDWR_BUFFER_SIZE_max is going to be approx. 7 MBytes. PSET is available from /proc/personality.sh, so we could automatically calculate the max size during ION boot-time. If something wrong, please correct me. Thanks, Kaz

Notes from BGW tests
by Pete Beckman 28 Oct '05

28 Oct '05

Hello ZeptoOS users (or those thinking about it for their BG/L). Yesterday we ran on 16 BG/L racks at Watson. The results were great. PVFS and ZeptoOS did well, and we learned a lot. A couple quick notes: 1) Thanks to Susan, we now have a "switcher" script that can be run from the command line. It will switch a partition to ZeptoOS and then back to the default with a simple command from the shell. This is perfect for installations that want to flipflop a partition between ZeptoOS and the default IBM setup for the purposes of testing performance or getting IBM support. Naturally, when you report a bug to IBM, you should do it against their default configuration, and "switcher" lets you easily flop back and forth (without Cobalt). The new script and documentation will be released in the next version of ZeptoOS, which bundled up in the next couple weeks. If you want a copy of the program now, let me know. 2) While running at BGW (20 rack machine at Watson), we realized that the default CIOD_RDWR_BUFFER_SIZE set to 4M by ZeptoOS is perfect for configurations that have 32 compute nodes per I/O node, but is too big for machines with 64 compute nodes per I/O node (16 per rack). On such I/O-poor machines, the CIOD will run out of memory trying to allocate extra buffer space for 64 compute nodes. Of course this is easily fixed with the ZeptoOS configuration tool. We suggest 3M for I/O poor machines. Similarly, machines that are I/O-rich, with 8 or 16 compute nodes per I/O node can probably increase the variable and therefore increase I/O performance. The next version of ZeptoOS will automatically default to the best number for your configuration. We are suggesting that IBM allow some of their 1 Megabyte node cards (twice the current memory) be made available as I/O nodes, even for standard 512M systems. Our Linux would be happy with the extra buffering :-) 3) On the BGW, The PVFS2 team tested PVFS2 on ZeptoOS up through 16K nodes writing to 33 PVFS2 servers. I'm betting that for those of you signed up for the SC05 tutorial, "S01: Parallel I/O in Practice" (http://sc05.supercomputing.org/schedule/event_detail.php? evid=5124) you may get a sneak peak at their results, or at least you can raise your hand and ask :-). In any case, they warmed the ethernet and hard drive with aggregate I/O speeds in the gigabytes/ sec range with various PVFS2 configurations. We also had a chance to test ZeptoOS with Jumbo frames. Worked perfectly. So if everything on your switch can be Jumbo, we recommend it. 4) The current version of ZeptoOS was also run with "Version 1" of the IBM BG/L software without changes. So no worries there. 5) Kamil and Kaz recently made some improvements to the ZeptoOS installation options. The improvements let you keep all the ZeptoOS files, even etc/rc scripts in a separate directory from your existing BG/L configuration. So if you want to keep all of your Zepto mods clean, and away from the IBM setup, that's now quite easy. In fact, we tested this on the BGW machine, since obviously IBM was not willing to give us root to install files :-). Instead, all we needed was a directory on /bgl, and our switcher script, and we were able to do it all without root :-) The installation improvements will be packaged up for release in the next couple weeks, or sooner if folks need them. 6) The ZeptoOS club is growing :-) Current users or exploratory testers include ANL, ASTRON, MIT, NIWS, EPCC, and of course BGW :-) Please let us know additional features you need (or just want). You can post them at bugzilla.mcs.anl.gov/zeptoos. Simply mark them "enhancements" and we will see what we can do. We have a couple things currently under way. The PVFS team has some sneaky plans for even faster I/O with clever hacks on the ION. We are also exploring the idea of running gateway daemons on the I/O nodes that could let you couple apps running on your BG/L nodes with external machines, either via GridMPI-style or WAN-style links. Thanks. -Pete
