你口袋里是有一堆东西还是很高兴见到我?

高性能计算（HPC）与您的朋友在夏季的一天看到你的朋友在耙子中看到你的哈利和管道的哈雷上的凉爽感凉。为准备我的Codecave Spring清洁会议，我开始看看我可以进入我曾经生长的Beowulf群集的服务器/工作站，这是我的孩子被命名为“Domo-Kun”的服务器，因为它看起来像牙齿的乌贼http：//www.domonation.com/肯定看起来完全自制，因为我拔出了主板，并将它们悬挂在我的服务器机架上的钢棒上，电源在一个货架上的电源和另一个货架上的电源，通过圆形电缆。我把laserpod http://www.laserpod.com放在后面，并在它转动它的群集时亮起。非IT伙伴认为，单独增加1000个Teraflops加上我的奇怪邻氏的UPS约34％。我爱上了我早期的VAX / VMS“只有”夹克日的聚类。我对那些集群的令人难以置信的持久性感到惊讶。不用说窗户和* nix hpc聚类选项就像吃一个覆盖着温暖的蛋黄酱到vax / vms geek。Windows的东西仍然吹嘘，真的是群集@ $％然后是其他任何东西。自2000年初以来，Linux呼吸了与蜜蜂的群集。如果你想要建造一个蜜蜂群，那里还有一些书，但诚实，他们糟糕的是啤酒少，少许足球豆腐感恩节晚餐与你的姻亲一起。 Your best resource is an article wrote by Robert Brown in 2004. http://www.phy.duke.edu/~rgb/Beowulf/beowulf_book/beowulf_book/index.html save your cash for new fishin' baits. There have been a few times in my career while I was huffing and puffing all over God's world that a cluster would come in handy on the road. Sometimes to showoff and other times to crack password files before rainbow tables really started getting good. By the way, check out these new improvements in rainbow table speed https://www.objectif-securite.ch/en/products.php#demo (YOWZA!) Sure I could ftp files up to my home system and kick off a process, but how fun is that? A cluster on the fly is what I need here. In walks a fantastic solution called; Bootable Cluster CD (BCCD) http://bccd.net/ BCCD is simply what it says. It is a bootable ISO that is preconfig'ed HPC clustering software. It clocks in at around 700Meg, has a solid community behind it and is updated regularly. The code jockey's at BCC wanted to be able to walk into ANY department with Intel based machines and have a parallel, distributed compute grid up and going. Simplicity is the key here. - Put in the CD - Boot the system - Follow the simple on screen menu option - Remove CD - Go to next machine, lather, rinse, repeat... Now the really cool thing about this is that since it is an ISO, it allows me to build out a non-destructive cluster right on the spot without trashing out the machine. I have built BCCD clusters with both PC, Mac's and even laptops with VMware without any problem at all...well, I did have issues with machines that had i810 video chipsets in the early versions based on GAR but now with version 3.0 based on Debian, I have not those issues any longer. You do need a DNS server and DHCP server up and going. BCCD can provide these services, but I find it works faster and saves RAM resources if you have an external one up and ready to go. But it's your call. Like any good ISO, you do have the option of installing BCCD on your hard drive and running a diskless cluster environment. Many network admins like this option since you are limited by RAM size as to how much data you can store in LiveCD mode. No problem with a few software packages, but they add up fast once you realize the serious honkin' horsepower at your fingertips. Once installed, the BCCD system will be the cluster head node, and boot other systems on the network to BCCD. Like Knoppix and Slax; BCCD uses the stable AUFS file system, which I believe is also faster then other FS options. Cluster nodes share the master node's root file system but each maintain a copy of changes to that file system as well. BCCD works great! It is about a turn key as you can get to firing up a HPC in your lab or anywhere on the spot. I have a friend (really, I do!) that works at a chemical lab and was going to get rid of a few older machines. I showed him how to use BCCD to build an HPC in his house to run his modeling sims based on PVM (parallel virtual machines) and he was floored at his gains and computing power. If your a hobbyist, educator, engineer or whatever and want to build out a cluster, you can certainly use Beowulf, OSCAR, Rocks, ClusterKnoppix hey even VMS folks find pure BLISS at http://www.openvmshobbyist.org I think if you give BCCD a try you'll be as hooked as the fish I hope to catch this year...Hmmmm...I wonder if I can code up a parallel app to help me catch more Bass...

It is so still that stars do not twinkle in the sky because there is no turbulence in the atmosphere to distort the light.
