LHC@home

End result - no crunching loss, and a slew of credits when I connect them up again =D

Borandi, please be aware that CPDN expects you to connect every 5 to 6 weeks and send trickle messages. Otherwise they think that you are inactive and they might reissue the work unit.

I could be wrong but I think the keyboard/mouse requirement is os based (windows for one). I have 4 boxes that run on linux with no keyboard, mouse or monitor, all of varying vintages.

A geek dream finally realised.
I have trying to get one these 8 proc Xeon systems for over a year.
*snip*

Using a Watt/Hr meter, I estimate I'm using around $65 a month. But then I'm running nine computers 24/7.

I presume you (and most everyone else) has their monitors off?

I'd like to hear what people's estimated extra energy cost is in $$$ that is attibutable to their farms along with how many machines they have.

166 pentium Win98

I'm working on rebuilding a pentium III and another 166 in storage...

WOW....at that price.......its gotta be uber fast...LHC look out !!!!

My 486 (AMD 586-133) does SETI in 12.5 days. It's not really worth it. SIMAP seems to be a good choice for slower computers. The 486 does it in 22 hours and I'm almost always first to return a result.

Fast action photography - the sort you see at boxing matches and football games - isn't fast enough to a University of Wisconsin-Madison scientist who is building the world's fastest camera. Pamela Klabbers, an Associate Scientist with the university, is leading a team to build a camera system capable of recording protons colliding at nearly the speed of light.

Dubbed the Regional Calorimeter Trigger, the "camera" actually represents several computer boards stored in an eight foot chassis that can process four trillion bits per second. Sometime next year, the RCT will be part of the 27-mile long Large Hadron Collider in Geneva Switzerland.

Proton collisions and the associated particles that they create may only last two-billionths of a second. Since the collision happens so fast, it's easier to take pictures of the aftereffects of a collision, rather than the collision itself. After a collision of two protons, many elementary particles are created, which, however, disappear shortly afterwards. In addition, a flash of light in the form of photons are also produced.

When the RCT detects the photons, the system starts taking pictures at one shot every 25 nanoseconds. However, not all the pictures are kept and the system analyzes every picture for interesting characteristics such as a stray photon or muon.

Not surprisingly, serious hardware powers the RCT. 300 sutom designed boards are working in a total of 18 crates. The camera has been in development for almost six years and so far has cost $6 million dollars. It is scheduled to be installed at the Large Hadron Collider in Geneva Switzerland in 2007.

Is the P133 really a straight Pentium (i586) chip?

Who can offer me any suggestions as to why this one out of four programs will not display the screensaver?

My guess is that since the detach / attach worked, it was that LHC had used some extra CPU time and was barred from downloading work in order to meet the resource shares that you specified.

Naw. Just people like DJRWolf bumped up their caches because they want to squeeze every last credit out of the project -- even if it slows throughput to a fraction of what we COULD do at the end of each study.

Yeah, there are a few people who have good reasons for a 1-day or even a 3-4 day cache. As wolf demonstrated, they're not why it's going to take a full week before we get anywhere CLOSE to finishing this batch.

Hi:

Can anyone tell me how many seconds per point (on average) for LHC@Home?
