Message boards : Number crunching : New credit system

( Message 2436 )

Starting with workunit 25683 we are using a fixed credit amount. For the current test workunit (1tng) this is 49.5. Please let us know how much credit/hour this comes out to on your machine.

I compared this fixed value with the credits I got for workunits starting with 19724 so far (for Windows I only took those into account which were calculated with the current application 5.04) and it looks good and quite reasonable to me:

Athlon64 2,0 GHz / Windows (6 results):

average time per workunit: 2 hrs 47 min
average claimed credits: 11.58 per hour
average granted credits: 12.11 per hour
claimed credits w/ new fixed credit scheme would be: 17.76 per hour ( + 53 % )

Athlon XP 2,1 GHz / Windows (8 results):

average time per workunit: 2 hrs 60 min
average claimed credits: 13.02 per hour
average granted credits: 12.01 per hour
claimed credits w/ new fixed credit scheme would be: 16.53 per hour ( + 27 % )

Athlon XP 2,0 GHz / Linux w/ BOINC 5.4.x (8 results):

average time per workunit: 3 hrs 39 min
average claimed credits: 6.46 per hour
average granted credits: 7.24 per hour
claimed credits w/ new fixed credit scheme would be: 13.54 per hour ( + 110 % )

Athlon XP 2,0 GHz / Linux w/ BOINC 5.8.x (57 results):

average time per workunit: 3 hrs 40 min
average claimed credits: 9.02 per hour
average granted credits: 8.66 per hour
claimed credits w/ new fixed credit scheme would be: 13.50 per hour ( + 50 % )

Pentium III 1,0 GHz / Windows (9 results):

average time per workunit: 8 hrs 30 min
average claimed credits: 5.55 per hour
average granted credits: 5.39 per hour
claimed credits w/ new fixed credit scheme would be: 5.83 per hour ( + 5 % )

Celeron 0,466 GHz / Windows (3 results):

average time per workunit: 19 hrs 53 min
average claimed credits: 2.57 per hour
average granted credits: 2.47 per hour
claimed credits w/ new fixed credit scheme would be: 2.49 per hour ( - 3 % )

K6-III 0,4 GHz / Windows (3 results):

average time per workunit: 37 hrs 54 min
average claimed credits: 3.32 per hour
average granted credits: 3.27 per hour
claimed credits w/ new fixed credit scheme would be: 1.31 per hour ( - 61 % )

Cyrix M2 0,25 GHz / Windows (1 result):

average time per workunit: 96 hrs 48 min
average claimed credits: 0.84 per hour
average granted credits: n/a
claimed credits w/ new fixed credit scheme would be: 0.51 per hour ( - 39 % )

Pentium MMX 0,166 GHz / Windows (1 result):

average time per workunit: 95 hrs 43 min
average claimed credits: 1.27 per hour
average granted credits: n/a
claimed credits w/ new fixed credit scheme would be: 0.52 per hour ( - 59 % )

Btw, I'll be offline for the next weeks. See you later!

Best regards

I also have a Pentium MMX crunching which hopefully finishes its workunit tomorrow. (...)

Workunit ID 23162

It's ready now, took a bit longer than first indicated. As expected it was deemed invalid against the two Pentium 4 D.

Here is another workunit, which was turned to an unexpected direction by HR and the new features of the 5.8.x BOINC application:

Workunit ID 20567

On the 11th of January I returned the first result with a Pentium III. On the 16th of January the second result was returned by an Athlon. Then two Pentium II/III-class computers did not return their results in time. On the 5th of February the third result was returned by a Core 2 and the validator reported 'Checked, but no consensus yet', which is no surprise.

Now the fourth result has been send to another Core 2. If it returns the workunit, it will most likely be valid together with the other Core 2 result. If it does not return the result in time, then it all depends on who gets the fifth. Fortunately we have not reached the limits for maximum error/total/success results yet.

Thrilling, isn't it? ;-)

@Alex, OK, converted to 5.8.8 and caught a WU. We'll see how long it takes..........BoincManager shows about 38 hours.

Thanks. Hope all goes well.

All my PCs are self-build (except my notebook) and so I usually keep them for a long time, even when they start to become obsolete. This includes my K6-III which has served me well since 1999. And so it is fun to crunch a few workunits with these oldtimers from to time to time.

I kept my 286 till 2002 (running Minix) and my last 486 (running WinNT) was disposed last year. :-)

Btw, I have found that ABC, RieselSieve with the sieve app. (not llr) and SIMAP with the simap app. (not hmmer) (the last two only with manually installed non-standard applications) are going well with the K6. All those applications seem to use only or mostly integer calcalution.

I guess I had it just ass-backwards..........I started starving some machines thinking that would leave the "few" available WUs for others.

Hello j2satx,

is your K6 still online? Maybe you want to grab one or two of these unsent results here

:

Workunit 24800
Workunit 25108

Of course we would still need a third one, then. But we have already shared the following quorum, which gave some nice credits:

Workunit 22173

Think about it...

This is the first project were I start to sell results... should I be worried? Could be the next, more serious stage of BOINC addiction.

I checked in it also doesn't compare to the K6.

Ok. I'd say if it does not fit into a larger group, you shouldn't bother about it. It's very rare.

No I don't expect that one to validate based on the current and previous experience. If you want to suspend that one for now, that would be fine by me. Pentium MMX is a Family 5 model and those do not exist in the current HR rules, but will be there in the new set.

No problem. I try to let it finish. It looks as if it would take ~ 3 days per workunit, which is not that bad at only 166 MHz core clock (most RAM is clocked higher today).
Even without credit for me you will get a result which you can compare if necessary. Since far more Pentium MMX have been sold than Cyrixes for example, I guess there's a chance that a few more will show up later, even if they are quite slow. At least there have been boards for dual Pentium MMX with up to 512 MB RAM, those could still do some crunching.

Regards and have a nice sunday.

I look forward to seeing how your machine does on Docking and how long it takes to run a workunit.

Hello David,

it is not very good at crunching for Docking@home even on clock-per-clock basis. The Cyrix M2 @ 250 MHz needed ~ 4 days for the workunit, on the same mainboard the AMD K6-III @ 400 MHz needs only ~ 1,5 days (both with application version 5.04). I switched back to the K6-III for now.

Alex, please give me a note when you get some credit (or not) for results crunched by the cyrix machine; We have to find out if it fits in any existing HR groups or will need its own (in which case we'll need some more cyrixes :-)

Hello Andre,

the quorum of the Cyrix M2 workunit is now complete. It has been validated against two Pentium II/III-class processors and was deemed invalid in comparison to those:

Workunit ID 20898

Well, if it is not too much of an effort, you could check it against the K6 results in the database, maybe it fits there.

I also have a Pentium MMX crunching which hopefully finishes its workunit tomorrow. Maybe this one also fits into the K6 class or is compatible with the Cyrix M2. Currently it shares a quorum with two Pentium 4 D, I do not expect it will be validated ok against them:

Workunit ID 23162

This is now hopefully fixed. I just dawned on me that I forgot to apply the patch we got from the world community grid people that solves this 'work committed to other platforms' problem.

Thanks for the fix. My K6-III now got another workunit.

@all: Btw, there are at least four results unsent for K6/Windows ( here and here ) and the last one gave the two other members of the quorum and me 124 credits. This was the first Docking credit at all for my K6. So if you have a K6 online, you might want to grab one of these results... perhaps.

"Message from server: (there was work but it is committed to other platforms)"
"No work from project"

I have the same problem here with my AMD K6-III currently. I guess the workunits available are committed to other platforms due to Homogeneous Redundancy. However, it is a bit odd, that your Opteron/Linux is not getting any work, because there are quite a number of compatible AMD K7, AMD K8, Intel PII and PIII. At least they were available... I hope they are not all switched off / detached now...

So the only thing we can do, I suppose, is keep them polling and crunch for other projects in the meantime. My K6-III is doing a little bit of ABC and SIMAP currently, as slow as it is.

Alex
