Re: Misleading Global Statistics

I have no technical knowledge to answer the apparent discrepancies. I simply installed the agent on 3 computers (don't know why stats show 4). They are all part of my home network. When I open the agent, it uses a "high-end desktop system" as the base for comparion, even though only one desktop is in my device list. In each of the comparisons, I show up at 196 or better. These are my devices:

Alienware desktop--3.8 Mhz, 4G RAM, 100% throttle
Alienware laptop (desktop replacement)--3.6 Mhz, 3G RAM--80% throttle
Toshiba Tablet--2.7 Mhz--2G RAM--100% throttle

All operate 24/7, 365. Am I doing something wrong except to throw massive processing time into the project.

Re: Misleading Global Statistics

Hi Sid Gibson,
You can check out your registered devices by going to My Grid - Device Manager and then using the drop down menu at the top to look at all your registered devices, not just your currently active devices. This will tell you when you installed the client on each computer.
Then select Device Statistics and use the drop down menu to see the statistics for every device that you have ever registered. Hopefully this will explain how you came to have 4 installations on record with the server.

For Sgt. Joe,
Whenever a client is registered with the server, it is assigned a unique Device ID. All results are sent back with this Device ID attached. The server always remembers this Device ID, no matter how many times you reinstall a client on one computer, generating a new Device ID each time. The count of devices is really just the number of Device IDs that have ever been assigned to your member name. By default, Device Manager and Device Statistics list only those devices that have returned results in the last 14 days or have been registered in the last 7 days, but the count is the total number of Device IDs that have ever been assigned to your member name.

Re: Misleading Global Statistics

SNLCSJwillows-VM, you seem to be making a few assumptions. First of all, work units come in different sizes. Over the years, work units have got larger and smaller, as well as the day to day variation in each unit or batch. Members contributing to different projects can expect to end up with very different averages per work unit.

As for runtime, multi CPU devices can do twice or four times as much work in a single day. There are even a few 12 CPU devices running on the grid. Also, the BOINC agent awards credit on the day a work unit is validated, not when it is returned. All this makes it very hard to draw conclusions from a single datum.

WCG are aware of the weaknesses in the statistics display, but they are not errors.

Re: Misleading Global Statistics

Didactylos, I'm quite aware of system differences! I'm also quite capable of looking at available statistics and deducing the cpu capability, and using this information - there is no doubt in my mind that there is an ERROR - either in reporting the statistics or in the way information was transfered (what I suspect) to the group when this member (since May 2005) transfered to the group (Nov 2006).
Just the 572 results per day for a single system should show you this (the other stats do NOT confirm this SUPER SYSTEM)

Re: Misleading Global Statistics

No idea who is being compared with whom, but unless u know the detailed info of a members choice of projects, the type of computer(s), the change of computers (speed and cores e.g.), the agent, whether suffering a period of very long WU's hanging or cycled thru WU's in moments (which would register as a result under UD agent) and a few more, there is absolutely no comparing and loads of assumptions enter the equation.

For the exercise pulled all the participants together in this thread, no one doing 572 WU's a day in this set, but there are those that do literally hundreds..... just look up RCTCgrid (added for amplification), who just en mass switched from UD agent to BOiNC and look at the Points per hour...... they are all on the low side, considering that there are machines that genuinely generate 80+ per hour, per core. Considering that I e.g. added a BOiNC agent April 06, which runs a benchmark of 8 per hour (56 UD points) and running 24/7 at 90%+ CPU efficiency, the 41 UD points per hour, is actually on the low side.....because they are a historical build from day 1.

Discussion Participants comparison

As for the team switch observation, when a member moves from one team to another, or was team-less and joins one.... the points only count for a team the moment joining a team until quitting a team.

To sum it up, i will not assume anything in these individual stats matters, know the device count is just a historical count of registrations, know that Sid twice registered the same computer (he 'told' us), know that from experience, views of anyone's hourly points is an 'opinion'.

cheers

PS, i know there is a team comparison page like there is for members, but never used it, nor do i know who to compare in this thread..... unless on BOiNC, it's not easy to find out someone's team.

Re: Misleading Global Statistics

There've been numerous discussions about devices in the past. Net is you can't delete devices here so X devices will not necessarily equate to X machines. The best suggestion I can offer for comparing yourself to like crunchers is to search on your username at http://www.boincstats.com and bring up the details on yourself. One of the links they have on that page is your ranking with others with the same number of BOINC hosts. That will just be you and others running BOINC - doesn't include those running UD but it's something. It just seems like anytime someone reinstalls the UD agent on a machine, it gets treated as a new device unless you make the right incantations in the right phase of the moon biggrin Never had a problem like that with BOINC.
