Message 529105 - Posted: 10 Mar 2007, 15:34:46 UTC

You may have missed this discussion, so I am posting it in a new thread, to get your attention.

We need a response from someone in charge.

There has been a recent change to the logic for the Top Computers. It is no longer the "Top Computers by RAC". It's now something more like "Top Computers that meet an arbitrary minimum credit threshold that is undisclosed." That minimum seems to be somewhere between 200,000 and 300,000.

Why? It is intentional? A mistake?

If it is intentional, why no announcement? Also, if it is to remain like this, there needs to be a legend or *something* on the Top Computers pages that explains how to read it. Because it is already causing confusion, and multiple threads started by people asking why things don't look right, and why can't they find their computer, which rightfully should be showing.

Finally, how do we get it changed back to the way it was, with no minimum total credit requirement? That is the way other projects do it, and it should be consistent across projects.

Thanks, and hope to hear from someone soon.

That is a relief...well sort of.

I noticed the change in the leaderboard a couple of days ago and couldn't find anywhere within the site why this has changed.

This host: http://setiathome.berkeley.edu/show_host_detail.php?hostid=3067426 should be in at least the top 5 with a RAC of 5,586.75 (at the time of this post) but is missing from that list.

The Thread in Question . . .

Top 1000 Computers . . . #999 with a RAC of 0.11?

Looking at the Top Hosts I can all the way to #1000 with an RAC of 1.73. But you can also order it by Total Credit. My guess is that the "top hosts" is based by total credit, however, with the option of listing those same computers by RAC. In effect if Nez stopped crunching eventually he'd be #1000 with an RAC of zero, but still #1 with total credit.

There are so many buttons and links I feel compelled to click them all. :)

I've red-x'd the thread to bring the issue to the other mods and admin.

No, we looked at that yesterday and the current cutoff for the Total Credit listing is 306321, but the lowest "qualifying" TC for RAC is currently 290190.

This implies that the Total Credit display listing is not just resorted to display as RAC.

The default ranking is by RAC. Yes, you can also, re-rank it by total credit. But you're missing the point.

Something is definitely broken. The 1000th machine (by RAC) should have a RAC of ~1215. You can easily double check it over on BOINCstats:

http://www.boincstats.com/stats/host_stats.php?pr=sah&userid=&st=900&or=16

Yet the 1000th machine (by RAC) on S@H has a RAC of 1.89.

And *none* of the top 1000 (by RAC) on S@H have a total credit less than 200,000. This is obviously an error.

LOL.... Good catch, I had forgotten to blame Misfit. :-)

So to Misfit, apologies and BTW.....

no need to list further. If "hiding" were so unpopular you would think less would be hiding them.

I don't know how much of a coincidence this is, but nearly all of the computer/hosts in the "Top Computers" with a low RAC seem to have the August 2005 stale results listed at the end their "Results for Computer" list.

Try, for instance pretty well any of these:

Seems to me that this "1000 list" problem may well be part of the "Stale Results" long outstanding problem,

I take offense when someone insinuates that our team is being secretive when actually is commonplace.
