somethink like this http://www.ips-bremen.de/produkte/sun/server_fire_v40z.php but not for Home :) many people are working in a large Company and has access to this Lucky People :) update just found this at EAH http://www.lsc-group.phys.uwm.edu/beowulf/alpha/index.html http://www.lsc-group.phys.uwm.edu/beowulf/medusa/index.html Our Beowulf has 48 nodes connected by a 100-base T switch. Each node is a DEC 300XL workstation containing a 300 MHz alpha 21164 CPU with 2Mbytes of cache, and a peak floating point performance of 600 Mflops. The system has a peak floating point performance of 28.8 Gflops, 8.45 Gbytes of distributed RAM, and 98 Gbytes of distributed disk storage space. The system was initially set up and running on May 4, 1998. Greetings from Germany NRW Ulli S@h Berkeley's Staff Friends Club m7 © |

Well, HT machines run as 2 virtual processors. Get a dual processor HT machine, and you will look like you have 4 processors, and crunch 4 WU simutaneously. My movie https://vimeo.com/manage/videos/502242 |

If everything goes right I will be running a quad xeon box in the next week or so. It aint state of the art but it is 4 processors(non ht) Scott " " |

A graph showing how many hosts have a particular amount of cpus in this project: Number of CPUs is on the bottom, number of hosts is the bars. |

Thats easy like on the 3 cpu's the board I am getting will run 1,2,3 or 4 cpu's so I guess the same for the others the 5 may be in a 8 cpu box and the 11 in a 16 cpu box.They may not need the full potential of what they have or it may be a $$ thing.

Hewlett Packard do a server that can have up to 64 CPUs. HP AlphaServer GS1280. Hate to think of the cost. And its too big for my house I expect. <img src="http://boinc.mundayweb.com/seti2/stats.php?userID=2036&trans=off"><img src="http://www3.telus.net/seti/teamtest1.gif"> |

HP Superdome Servers has up to 64 CPU`s, so far i know. In the company where i work there are hp superdome machines with 32 CPU`s. |

The Unisys ES7000 is an Intel based 32-cpu capable box. Processors are added in groups of 4 Xeons at a time. We got one of these monsters where I work in our data center. It needs to run Windows 2000/2003 Data Center Server to see all 32 in a single image. It's used for database activity and data mining. If only I could run seti on it for just 1 weekend!!! I myself at home got several dual, quad and an 8-way. Most are Pentium 3 Xeons without hyperthreading. Hyperthreading didn't come out till Pentium 4. It's amazing how cheap you can put together one of these beasts if you know what hardware you're looking for and use EBay. Pentium 3 Xeon machines have come down in price considerably. They are all Compaq servers such as 2500, 3000's, 5500's, 7000, ML530's and 8500. I use these machines as desktops, but they are restricted to running server-based operating systems such as NT, W2K and W2K3. |

I recall that DayStar once made MP PPC clones in the 4, 6, and 8 CPU variety - Think they were all PPC601s... |

Yes, but notice that there is no price, so they must be free ... |

> Yes, but notice that there is no price, so they must be free ... > Here are the prices :o Start at $10k! I imagine the fact that they can be plugged into a standard wall socket (110V 15A NEMA type plug outlet, 1500W at wall (peak) 96 node version) means that the savings in electickery will offset the cost of running similar individual nodes (I hope). Also the foot print would be pretty small as the largest 96 node machine only occupies 17"W x 27"H x 25"D enclosure (includes casters). Dunc |
