Check the front page. There are no WU to send out so you wont get any work.

If WU are available, try resetting the project.

Always check the messages - sometimes some projects only produce certain amounts of work for different platforms.

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.

Actually are you sure? I have a WU from an old computer that was d/l on 8 Nov 2005 18:55:37 UTC, and last contact on 10 Nov 2005 8:07:40 UTC, and that WU hasnt been sent out again. Your rule would only apply if they changed the settings to include the 5/6 week 2nd sendout on the latest update.

Darn... that leaves me with few options. One thing would be to take out the HDDs and put them in a temporary computer to upload the WUs. I suppose that would work.

Way to go Perle!

I'm a student which is moving into a house next week in which I have to pay electricity.. so I'm having to strap all but one of machines with CPDN and cart them to a place I know where I can get free electricity, but no internet. End result - no crunching loss, and a slew of credits when I connect them up again =D

So how much was that Proliant beaut? =D

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.


The mouse/keyboard check is part of the BIOS POST... so OS independant. I've got several machines here and those above 266Mhz above have the option to turn the check off. I also have it written on each case whether it requires a keyboard and mouse to start up :p

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


Thats a nice bit of kit! Where I live, nothing like that ever seems to materialise (I live amongst the unwashed masses it seems... no-one knows how to use ebay up here) - I would always have to pay some extortionate amount for delivery.

I also had a power surge the other week... blew a hub and a 4 way plug splitter. Since then I've had to reinstall XP on my main machine, and lost all the other IP settings for the others. Only just now found enough time to get half the machines back up and running. It's a busy RL...

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.


As I'm a student, its great for me this year as my electricity is a fixed cost in my rent :D But next year I'm using a meter, so bad for me :(

166 pentium Win98

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


What I'm doing (I have a 133,266,333, i.e. slow machines like yourself) is slowly removing my slowest computers and replacing them with dual processor machines. They use roughly the equivalent power but with more crunch ;) So if 10 machines cost $50, 5 dual machines would only cost $25 (for example) :D :D

LOL I bet most of that price is tied up in the 64 GB RAM. BOINC wouldnt need that much ;)

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.


SZTAKI is also a good one for slower computers. I put it on all my 400Mhz and below.

From http://www.tgdaily.com/2006/02/08/uwisc_fastest_camera/


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.

What version of BOINC are you running?
What LHC version are you running (should be the lastest automatically)?

My girlfriend has trouple on her widescreen laptop (15.4") seeing some screensavers - particularly LHC. She uses latest version on both BOINC and LHC.

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.


Not possible - I set to accept work from only LHC (disabled work fetch for all others), only had 5hrs computing time left on WU's currently downloaded, and a 10 day cache. The WU's it needed to process had a deadline a week into the future.

Just everytime the BOINC messages said: 'not sending finished work or recieving new work' which I clicked update.

Bleh on some of my stations other apps do this too.... :((

I had to detach and reattach. Now the work cache is full.
But LHC seems to think I've got 2-3x as many WUs as there are on my screen.
I dont want to horde those WU's from people who want to crunch!!!

Hi all. Wondered if I could have your two cents... :D

Ok I've got an X2 4400+ on LHC.

It d/l WU's, processes, sends back.
ATM it wont accept any WU's.
I check the computer on my LHC profile, and there are loads of WU's that LHC says that it sent to the computer. But my computer hasnt got them.
As a result I think LHC wont send any more.

Anytime I send a request I get:
'not sending or accepting any new work'

I tried increasing my work cache - no effect.

Do I have to reset the project, or is this a DB issue?

BTW I only have 5 primegrid WU's left (5hrs computing time) so I have an 'empty cache' as it were.

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.


I have a 4 day cache on my X2 4400+, and it got 96 WU :D
I also have a 4 day cache on my P133, and its just started its second large WU (4 days per 1,000,000 turns).

I must have done ~750 WU of this batch with my machines - some 1000 turns, some 1 million. Never missed a deadline, only one computational error :D

Hi:

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

Mark Reiss



Seeing as you have lots of credits, then you (should) know:

An average computer gets 100 credits/day.
This is general across all BOINC projects (as far as I know).

Therefore it depends on:

a) How many computers you have
b) How fast your computers are.

An average computer, I find, is around 800Mhz.
