What is the oldest, thus slowest system that is crunching E@H?

What is the largest "farm" that is crunching for E@H?

I'd like to know...

One way to look for this kind of info is to go to http://www.boincstats.com/

ON the left hand side, click on the Einstein@home link, and when the page reloads there will be options below it.

Click on the option for breaking down the stats by cpu.

A list appears of the top 100 cpu types in order of total credit. That is not quite what you want yet, but bear with me for a minute.

The four columns of figures are:

Total credit: This means the total credit that kind of cpu has supplied this project, totalled up from the time the project started.

Average Credit: The name is a little confusing here: it is not the average per cpu, it is the average over the last few days (14 days???) totalled up for all cpus of that kind. Some people call this Recent Credit, Recent Average Credit, or RAC.

Credit per cpu: This is the total credit for this kind of cpu divided by the number of them that have ever contributed to this project.

Average Credit per cpu: This is the total RAC for these cpus divided by the number of them.

That last one looks interesting: the oldest cpu is likely to be at or near the bottom of the list if we sorted it in reverse order of the last column.

Click on one of the little arrows below the title Average Credit per CPU: the column sorts in the order of that quantity, and one of the arrows will give you the top 100 (in decreasing order), the other arrow will give you the bottom 100 in increasing order. It should be obvious whether you have the correct little arrow from the figures in that column, and from the kind of names of processors you get to come up.

Roughly speaking, the cpus that have donated least credit per cpu in recent times will be the oldest.

Of course this is not totally accurate: someone might run their cpu only 1% of the time on Einstein, or something. That must be how that IntelItanium got to such a low position! What is sure is that the slow machines cannot get very high up the list, so they must be in that bottom 100 somewhere. If you know the historical marketplace better than I do, you might even be able to pick out the oldest by eye.

Other stats sites have similar facilities: that is part of the fun of BOINC, that people like Willy (boincstats) and Mundayweb have provided tools for us to find this sort of answer on an automatic basis.

enjoy surfing the stats...

This one is even eaiser: on the E@H front page, click on top participants.

The largest farm has got to be run by one of the top few participants, I'd say. Exact winner depends whether you mean largest in terms of number of machines, total GHz of machines, or total contrib to E@H (remember to get to that position you've gotta be a serious boincaholic, and would be crunching for other projects as well).

If you want to count machines, just click on the participant then on view thier computers.

There may also be a way to do this on boincstats, but if there is I will leave it to you to figure out.

Sorry ~~gravywavy,
What I ment to say is, I know that it is stupid to ask such a quastion, but that the two extrimes would be such a contrast.

Hope I didn't offend you ...sorry agine.

If you don't know, and honestly want to know, then it is never stupid to ask the question. In that case it would be stupid to allow embarrassment to keep you quiet.

In my opinion the only stupid questions are the ones where people ask somethig they already know in order to get an argument going, or any other example where they main point was not a genuine request for new knowledge.

I'm a volunteer here, same as you. If I don't feel like answering your q I just won't, it is as simple as that. Maybe someone esle will answer, or maybe they won't. So keep asking Greg, sometimes you will get answers, sometimes you won't.

Thank you ~~gravywavy, very

Thank you ~~gravywavy, very kind of you. By the way I just got a 4 port router, and am looking forward to bringing to bare more systems to these projects.

Thanks agine.
