SETI: How many computers do some of these Top 1000 Users have?

[Smoke]

I got an idea this morning about working out how many computer systems, on average, are required to put out a specific number of WUs. The thought then occurred to me that it would be interesting to see how may computers some of the ?Top 1000 Seti Users? must have to produce the WUs they do each day.

I?ve constructed an Excel Worksheet of the Top 1000.

1st I converted their Average CPU into a decimal format. (7.5 = 7 hrs 30 mins)

Then I computed their average WUs per day based on the past 3 weeks. This may not be accurate for those that dump WUs so just remember that when looking at the results.

I used the following to come up with an average CPU per WU.

800 MHz 9.0 hrs
1000 MHz 8.5 hrs
2000 MHz 3.5 hrs
2500 MHz 3.0 hrs
3000 MHz 2.7 hrs
3500 MHz 2.2 hrs

This is in Intel MHz equivalents and I converted AMD times.

Now it is not that important for this analysis that the above be very accurate ? an approximation is good enough.

If you have a 56k connection these will take a while to download for they are each approximately 1 MB in size

http://smokeball.gygabyte.com/Top1000_Total_WU.htm
This is my analysis of the Top 1000 sorted by their ?Rank?.

http://smokeball.gygabyte.com/Top1000_Systems.htm
This is the same spreadsheet sorted by ?Number of Systems Required?.

I?ve highlight in YELLOW all of the TeAm AnandTech Members in the Top 1000.

It would be interesting to hear how close some of the ?projections? are to ?true life?. So if our Top 1000 Members could comment, it would be helpful to see if this analysis is valid.

Let?s consider this a work in progress. If you see any major flaws in my logic, please point them out.

Nice work Greg..

The calculations looks about right, but my average time is way off..

Currently I do around 4.5 hours
-------------------------------- (Spec) (time on) (avg. wu/day)
1 system, doing 19 hours (I 266) (24/7) (1.1)
2 system, doing 10.5 hours (A 600) (16/5 - 24/2) (1.5 - 2.3)
4 system doing 4 hours (A 1600+) (16/5 - 24/2) (4.2 - 6)
1 system doing 3.5 hours (A 2100+) (24/7) (6.4)
1 system doing 2.5 hours (A 2600+) (24/7) (9)
X system doing 4 hours (A 1600+) (8/5) (1.8) - This is depending on how many are at the office(but usualy around 5-8)
X system doing 4 hours (A 1600+) (8/5) (1.8) - This is depending on how many classrooms machines are installed
X system doing 3.4 hours (A 2000+) (8/5) (2) - This is depending on how many classrooms machines are installed

So if we calculate for 57, then 5 machines from classroom, doing 12 WU/day then its there..

I used, of course, the current average CPU as published by S@H since I have no way of getting any better data on all of the Top 1000 Users.

The average CPU so published by S@H will most likely not reflect the current situation for long time Seti Users who have upgraded and added new systems.

So how many computer do you have, contributing to your numbers on an average day, soni?

 

[JWMiddleton]

Interesting stuff Greg! Mine is off due to Matt (G19) and the contest. His average is 10h47m, so he is really dragging down my overall average, but I'm not going to complain!

So, does The Ministry of Serendipity really have 2,942 computers?

 

[soni]

Around 14-17... (doing around 45-50 WU/Day)

Based on my list, its the 5-8 (max 14, but then its bad for business, since those people dont do anything) at the office thats variable, the classrooms are rarely installed, since most classes install their own software/OS.

Someone posted a link to the breakdown of The Ministry of Serendipity once. It's a rather large mini-team, like 60 or 80 members if i recall. I tried searching for it recently but came up empty & can't remember who posted it. I think it was in one of HB's daily stats thread.

Is this what you were refering to?

So the spreadsheet has overstated the number of computers that Soni has by a factor of 3 or 4. Hmmm

Let's see what others report and we can just divide the projected number of systems by some factor ( 2, 3, 4, ?) to get a closer estimate.

BTW, some on that list are known cheaters. Check out Ant! This known cheater has had his account nicked and even deleted one or more times but comes back time after time with a new account.

I have also thought of drafting a letter to the S@H Admins suggesting that if they do not do an "End of S@H-1" audit and clean-up, I will not participate in S@H-2. It seems to me that would be the "least" they could do to encourage "true crunchers" to continue on with the project.

I bet most of you feel the same way.

Is that supposed to be the composition of the "Ministry"?

No, i was thinking it showed a whole breakdown of the mini-team, membernames, average WU's a day, total Mhz per person, etc, that sort of thing.
Then again, maybe i'm all wrong too.

 

[soni]

Greg, its not a factor of 4-5, more like 4-5 computers

Just notice my current average is around half the lifetime average.
But since many of my computers only run part time, its almost the same

 

[Smoke]

If you are only using 4 - 5 computers and you are a typical USER then my tables are way off.

I notice for TeAm Smokeball, it estimates 64 computers which is not too far from the actual. :Q

TeAm Smokeball has 52 clients and I have 8 computers myself (currently running).

I think he means you're off by 3 or 4 on the total # of computers he's using, not by a factor of 3 or 4.

 

[soni]

Well, thats more like it
Meaning about 5 computers off, not a factor of 3-4 (That would be like 3-4 computers doing 50 , possible but since im mostly AMD 1600+/2000+ not likely)

I believe if you look at the top of the page at "The OCUK supercomputer" it has what you are talking about.

For example

 

[Spacehead]

Yeah, that looks more like it. I guess i thought it was a breakdown of the The Ministry of Serendipity when i saw it before.

Thanks.

I know the feeling Greg. I see this person on another team, which i won't name, it's just my opinon, that when he joined this team he asked the old question, How can i do a lot of workunit's, and someone replyed, with a lot of computer's, with which he replyed, i could never afford the electricity. WELL, within months this guy went from 10-12 a day to i beleave 400 a day, and now i'll just say he's between 1,000 and 2000 a day. Going though post's on there fourm it's allmost never asked and i don't think it's ever answered where his output comes from.

Thanks (also to Spacehead) soni for helping me to understand more clearly. So then it looks like my tables may not be that far off.

And I got confused by my own tables ... I looked in the wrong column and thought there were 57 predicted computers for soni instead 19.

It's the GREEN column ... (me tells self). LOL

gg,

I have always felt that FOUNDERS (or persons acting in that capacity ) should monitor their own teams for any possible infractions. It appears some are more deligent than others in that regard (no names, of course).

Very interesting reading...

Thanks Greg.

Actually I think what would be more interesting would be to figure the amount of bandwidth needed by the top 1000 users. I could possibly believe that a person who works at a company with a large amount of computers could get it loaded on them to process. What I find hard to believe is that companies would be able to justify the bandwidth usage that the 1000+ WU/day users would take.

 

[Smoke]

Good idea, Crazee. Someone, that knows how, ought to work that up ... (that leaves me out).

 

[PieDerro]

Well INTERNET bandwidth would be quite simple - just 350KB times the number of workunits returned per day. (The 350KB includes both upstream and downstream).

INTRANET bandwidth would be more difficult and would depend on how many machines there are and how many levels of SETIQueues they have set up (each additional SETIQueue in a heirarchical structure would double the required bandwidth levels if all results are queued through the queue heirarchy).

I know my INTERNET bandwidth is about 170Megabytes per day. I'm guessing that my total Intranet Bandwidth would be about the same, since I only have one Setiqueue at each site. So, overall, it's not that taxing on my network.

I can imagine some of the really high end producers (those pumping out 2000-3000 WUs per day) would be putting some kind of strain on their company's internet connections at least! I mean, that's around 700-1000 Megs per day of internet traffic alone!

From what I see, the average sized WU is about 350KB. so 350KB * 1000 = 350MB

I'd doubt that a large company would find that 350MB/day is hurting their bandwidth too much.

In fact, I could do it easy on my cable internet here at home... how just how to get 1K WU/day is the question LOL
