Message 149970 - Posted: 10 Apr 2021 | 18:24:03 UTC

I have one host with dual 3080s that has generated a bunch of valid WW jobs (~400 as of this writing, over the last ~3 days): http://www.primegrid.com/results.php?hostid=782330&offset=0&show_names=0&state=4&appid=33

But http://www.primegrid.com/gpu_list.php#WW shows nothing for 3080 under Windows right now (there is only the Linux entry).

What is the update frequency of the Top GPU Models page?

Thanks
Tuna

I believe there need to be some minimum number of cards of a type before the type shows up.

Thanks!!

Hmmm.... Assuming that's the case, methinks including the number of cards in the PG system next to each listing in parentheses would be nice. That would also make it possible to show the cards with low counts, but maybe with an (*) to indicate visually that the perf value is statistically not yet mature, while still giving the audience an idea.

Just a thought...

Even before The Science Cloud and its many (sometimes short-lived) hosts, Linux had the lead by numbers of machines: Page from 2019-Apr-29

Not sure how much you must upgrade or modify your OS before BOINC sees you as a new computer.

However, in terms of recent credit, Windows is the leading OS.

probably because this is how the driver reports the GPU name.


I wonder... On Windows, the driver comes from NVIDIA. And, all current NVIDIA drivers refer to the cards as "NVIDIA blahblah". Yet, the "NVIDIA Geforce" vs "Geforce" name duplication in the Top GPU Models page exists under the Windows columns, therefore that is not due to Linux drivers adding to the mix. Maybe the NVIDIA drivers changed sometime in the recent past to add the "NVIDIA" prefix.

In any case, the way it is currently itemized feels... ...not meaningful.

Maybe the code that generates that data that results in this page should ignore any "NVIDIA " (and, similarly "AMD ") prefix in the card name (along with the trailing space!), which would then combine the perf numbers of cards more intuitively? Separating perf numbers along an arbitrary line of when a company decided to include the company name in the driver report seems non-scientific.

Unless there is a whole another reasoning behind all of this.

I believe there need to be some minimum number of cards of a type before the type shows up.

Thanks!!

Hmmm.... Assuming that's the case, methinks including the number of cards in the PG system next to each listing in parentheses would be nice. That would also make it possible to show the cards with low counts, but maybe with an (*) to indicate visually that the perf value is statistically not yet mature, while still giving the audience an idea.

Just a thought...

I entered this on BOINC GitHub as https://github.com/BOINC/boinc/issues/4357. Seems PrimeGrid page might be having a problem. The question from BOINC dev was:

Looks like this statistics is build on last 2k results.
@TunaErtemalp, is it possible that results from 3080 are not in the last 2k batch on results of this particular app for Windows platform?


Unless my 3080s' WW results (and currently they are working on AP27, with 1000+ results so far, similarly missing from the AP27 section of that page), I'm wondering if the window of data that page is based on or frequency of its generation is having a problem...

I discussed this with Michael Goetz privately. Here are the relevant excerpts, with his permission, to explain what I am seeing and to close this thread:

Michael Goetz wrote:
. . . there's a lot of things that can mess up the statistics. I think in this particular case, the problem can be boiled down to "too much of a good thing" (with "good thing" being defined as "lots of results").

The database query needs to run fairly quickly. It can't be slowing everything down, and, practically, there's no limit on how many results could theoretically be eligible to be included in these statistics. These results are cached, so only one page per day actually calculates the data, but if you're the person looking at the page when it has to recalculate the display you don't want to wait five minutes for the page to load.

Here's a query that's derived from the code in that page...

select count(*) from result where appid=33 and app_version_id in (select id from app_version where appid=33 and plan_class not like '%cpu%' and plan_class not like '%AVX%') and elapsed_time>10 and validate_state=1; +----------+ | count(*) | +----------+ | 56016 | +----------+


There's 56 thousand results that should be considered for these performance statistics. However, for performance reasons, I include a "LIMIT 3000" clause in the real query, without an "ORDER BY" clause to avoid having to sort all the rows. The database is therefore returning, in this case, a relatively small *and completely arbitrary* subset of the results.

Note that the WW challenge cleanup ended yesterday, and the WW purging was enabled, so before yesterday it wasn't 3K out of 56K results; it was 3K out of about 500K results.

Idiosyncrasies about which GPUs are included are, therefore, probably due to the small and arbitrary subset of results being chosen at a particular time when you're looking at a subproject where there's a lot of results. The timings are probably good, but you may get days where some GPUs are excluded because of bad luck.

. . . Crystal-clear now. Although, my database internals work 30+ years ago makes me think that, depending on the implementation of the engine, LIMIT might keep returning arbitrary yet no-so-random data, i.e. rather stable over time. That might be one of the reasons why stuff like Ellesmere GPUs still show up, day after day.


Michael Goetz wrote:
Probably. . . . I always knew the performance numbers would be wacky. There's just too many things that will mess them up, including results that say they ran on GPU X when they actually ran on GPU Y. So crappy numbers are par for the course.

But I wasn't really expecting GPUs to go AWOL like this. Thanks for bringing it to my attention.

if you're the person looking at the page when it has to recalculate the display you don't want to wait five minutes for the page to load.

If that is the problem, then it feels like the best thing to do (if possible) would be to not allow viewing the page to recalculate it. Calculate it once per day on a cron (or even once per week) and just always display the most recent page, then the LIMIT on the query could likely be increased.
