I have a 450MHz p3 crunching Rosetta and Einstein and I got to thinking - there have to be even slower computers crunching BOINC projects.

So, post your entry (with link) to your slowest cruncher. The only rule is that it has to currently be active and crunching a BOINC project with successful results.

I want to see what old boxes you people have running!

Well, yes. I have a 200 MHz Pentium crunching a few projects. I had a 90Mhz Pentium crunching until it died.

I believe that someone had a 45 MHz Pentium running. I have heard about someone trying to get a 486 to crunch (don't know if they succeeded).

BOINC WIKI

I believe that someone had a 45 MHz Pentium running.

The slowest speed Pentium ever made was a Pentium 60MHz. Unless it was underclocked, it must have been at least that fast.


@MattDavis, I had a Pentium 90MHz crunching six months ago, but had to take it down due to energy costs. :(

I have a Pentium 90MHz laptop with 32 megs of RAM. How much RAM did yours have? If you had 32 and it worked then I'll hook it up to a BOINC project.

90 mhz laptop? haha :P

Please don't hook that thing up. Save electricity and prevent global warming! :)

It had 96MB of RAM. I believe BOINC needs (or needed when it was taken offline) 64MB free after startup.

I'm currently running an IBM 380Z laptop. It is a PII-300 w/ 96MB RAM, 4GB disk space running Windows XP. It is maxed out on both RAM and disk space.

It's running Chicken's optimized MMX app and takes approximately 175,000 to 180,000 seconds to complete the standard 62 - 67 credit WU, depending on AR.

All it does is SETI practically 24/7; All SETI All The Time.

Labbie's 380Z

If it didn;t use so much power I could hook in an old Compaq server that is a Pentium Pro 200 w/384 MB RAM, but it would probably take a week to complete a single WU.

EDIT for typos and BBCodes

Wow!! That beats mine. I may have an older one laying around somewhere but in the interest of fairness (not putting a machine together just to win the contest), I concede to you, Ranger.

hey i had a 486 with 64 megs. that was on classic.

BOINC itself doesn't require any particular amount of RAM, nor does it use a large amount of CPU time.

Before setiathome_enhanced, this project had a minimum reported RAM limit of 64 MiB, so someone who tried a 32 MiB host then would have been refused work. Enhanced has lowered that limit to 31 MiB. If you run Windows on that system, BOINC will report it has slightly over 31 MiB but for Linux the reported memory would be well under the limit. But the Scheduler doesn't really believe any small memory report and boosts it to 60000000 (60 MB) before checking whether it can send work to the host, so you'd get work anyway.

The low memory would be seen by S@H, and it would turn off graphics and a caching routine which speeds up chirping but needs an extra 32 MiB. S@H and BOINC together would end up using about 20 MiB. If the operating system can reside in the remaining 12 MiB and not force S@H data into the swap file too often, S@H should run well enough to meet deadlines.

There may be other projects which would also be suitable, but I don't know of a comparative list of project requirements.

OK, I un nominate Josef Segur. I did some reading and it appears that host is a Pent 200 with win95. Win95 is still impressive in it's own right. Here's a snippet from his post at beta linking his "Pentium 200" to the same host I linked to.

116) Message boards : : Number crunching : New deadlines, 4.34 days - 70.76 days...
Posted 128 days ago by Josef W. Segur
--------------------------------------------------------------------------------
OK, the estimates and deadlines have been reduced to 75% of their former values, except for the highest angle range which was reduced to 50%. I don't think that induces any new problems, we're simply in the same bad state where work that will be rare once the app goes mainstream will screw up work fetch for the normal kind of work.

Quick calculations show that my 200 MHz Pentium system will be easily able to meet deadlines.

can you place a vote for someone else? If so I nominate "josef W. Segur" who if I remember is running a 486 with WIN95. his host with nearly 6k points. He also still has it on the list at Beta.

Go Joe.

Thanks, but that Win95 "unknown, unknown" system is running a Pentium 200 MMX overdrive CPU so doesn't quite qualify in this competition. It's hostid 6025 on Beta Test and should complete a second WU with my build of 5.17 in less than 3 days.

I vote for this one: 2622534. Haven't seen less MFLOPs/sec yet... :o

Cheers
Andy

I think you would need atleast 64 becauses my seti is using 64 per WU process and 5 for the boinc process, over 120megs in total.

Yes, but it's only learning how to crunch: "new workunit has 258:25:10 under the 'time to completion' column".

It is a P 233MHz, so no way to win the contest.

Peter

I have access to a P75 at work, Im gonna ask them if they will let me bring it home and crunch number on it. I've already got weird looks from them when I said Ill take 6 of there old PII 700's. Nuts I say!

I had a 486 running a project but I'll be damned if I can find it in my stats.
It is an old Toshiba notebook, maybe it died and has not reported in months, who knows.

This is a pretty slow one that I run for Leiden

http://boinc.gorlaeus.net/show_host_detail.php?hostid=5896

Here is another one of my old dogs -

http://boinc.gorlaeus.net/show_host_detail.php?hostid=6290
it was running Hash Clash when they have WU's but the web site is down so I can not post it here

And other that used to run Rosetta - I forgot I even had it running - looks like I might need to find it and power it back up.
http://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=285130

This I had this one running several projects - most recently I tried it on Chess but chess wont run on it, I think it is a winme problem

http://www.chess960athome.org/alpha/show_host_detail.php?hostid=22977

And I think the slowest machine I have running - and the slowest that has been posted here I think. Used to run SETI before enhanced came out, now the only thing it can do is Pirates and 24+ hour Leiden WU's (2 min on a Pent D)
