Re: CPU Time 15 minutes, Zero Percent!

681.2 credit claimed LOL!
I got like 2 results returned today, since 2 out of 3 machines R doing Dengue (my laptop isn't even going to try). It likes the 128 meg requirement of Rice (and the 7hour and it's done!)


I have and old slow AMD 64 Jack. It would take forever to do these jobs, although it has 2gig of RAM in it and is capable of completing them. I'm just letting it carry on doing HCC. It may join in later when the C type jobs become available. Any type of job completed helps all of the projects here. Rice is a great project too and is well worth doing.

Re: CPU Time 15 minutes, Zero Percent!

Personally I have one running in a Q6600 at 3.16 GHz and it should last between 39 and 40 hours (average 47 minutes between checkpoints - 2 %).
Complete. No noticeable trouble.
Elapsed time: 38:45:57
CPU time: 37:37:19
Uploaded files: 91.50, 62.27 and 30.89 KB.

Edit:
PS: Thanks to my wingman for having returned it quickly. smile


jm, It is I who thanks you for being quick :) This could have been the first valid result for the project. :) btw, the other half is me on this work unit.

Re: CPU Time 15 minutes, Zero Percent!

1st one done, and of course Murphy was in the neighborhood to coach BOINC [6.10.32] to immediately switch away after the last checkpoint, sitting there with 100% "waiting to run"... so the micro-managing finger interacted and shuffled it around to give it about 1 second to pack up and prepare 3 files totaling 180kb raw for upload.

erlc_ b025_ ps0000_ 1-- 1112084 Pending Validation 17-2-10 17:31:58 19-2-10 16:53:47 44.91 841.7 / 0.0

Imminently 3 more finishing, a genuine, 64 bit client over-claim (though I think some lenience is in order) ;P

Keith,
It's the second time that we happen to be crunching the same type A together! The previous time was during the first betas.
Although I am glad to crunch with you I would be even more if you were not underclaiming so much, you cost me many credits each time**. smile
18.5 credits/hour is not much for a machine crunching at this speed. A 32-bit one I guess?

Cheers. Jean.

** If I remember well, for the beta it was even worse. You were so low that it has not been averaged and I have been granted your claim. crying
Never mind... smile

Re: CPU Time 15 minutes, Zero Percent!

New estimates this morning :

i7 920 @ 3GHz : 8 units simultaneously - 50 hours per unit
Q9450 @ 3GHz : 4 units simultaneously - 30 hours per unit
Q6600 @ 2,4GHz : 4 unites simultaneously - 40 hours per unit
T2050 @ 1.6 GHz : 2 simultaneous units - 100 hours per unit

My Pentium 4 doesn't support this project because is needed 750 MB ram or above.

Update :
i7 920 @ 3GHz : 8 units simultaneously - 48 hours per unit (+/- 1h)
Q9450 @ 3GHz : 4 units simultaneously - 28 hours per unit (+/- 1h)
Q6600 @ 2,4GHz : 4 units simultaneously - 45 hours per unit (+/- 2h)
T2050 @ 1.6 GHz : 2 units simultaneously - 90 hours per unit (+/- 4h)

Etonnante différence entre le Q6600 et le Q9450.
La seule différence de fréquence aurait dû donner un écart d'environ 7 heures de calcul, or ici il y a 17 heures d'écart.
Le cache L2 de 12Mo du Q9450 par rapport aux 8Mo du Q6600 doivent avoir un impact significatif pour ce projet, le reste du matos étant très similaire entre les deux ordinateurs (4Go ram, XP32 SP3 pour les deux)

A surprising difference between the Q6600 and Q9450.
The only difference in frequency would have given a gap of about 7 hours to load, here or there 17 hours apart.
The L2 cache of 12MB of Q9450 compared to Q6600's 8MB must have a significant impact for this project, the rest of the hardware is very similar between the two computers (4GB ram, XP32 SP3 for both)

Re: CPU Time 15 minutes, Zero Percent!

Your Q6600 stock is now right on my mean mark. The actual range I've had so far was completing from 44.6 to 46.6 hours.

Surprises... maybe higher speed RAM is also adding significantly to improve performance? Got DDR2-666 in mine... can't be clocked up over 553, the BIOS not updated by mnf for 3 years... a very lowly board in this off-the-shelf quad. Still contemplating to get a Q9450 replacement. Fits the mb and runs 60 Euro here.

Re: CPU Time 15 minutes, Zero Percent!

Oui, la mémoire est cadencée plus haut sur le Q9450 (936 MHz) que sur le Q6600 (800 MHz), du fait du FSB plus haut et de l'overclocking appliqué sur ce dernier.
