It is possible that SETI optimized clients take the role of inflating credit in large scale...CPDN Spinup was a small project comparing to that. Or was it optimized Einstein during the mentioned period?
Anyway, I would point to optimized clients...

Thanks Zain for your dedication to what you are doing, good job.

Being interested in statistic methods, would it be possible to make a graph of total credits together with total benchmarks of all machines? I\'m interested in correlation or course but can see it from graph as well...

(can make it myself but do not posses raw data)
3) Message boards : Number crunching : Fastest Completion Times for WU (Message 25070)
Posted 2849 days ago by Profile Honza
Last one I\'ve completed was about 1400 hours.
Prediciton for a new ones are about 1300 hours which is quite accurate.

Completion Times gets corrected once you finish some models.
But method suggested by Mike are most accurate.

Hi John,

I can see your computers and results fine - http://climateapps2.oucs.ox.ac.uk/cpdnboinc/hosts_user.php?userid=319

If server asks you for email/password again, you need to have cookies enabled in your browser.
(you can also use authenticator in account_climateprediction.net.xml in your BOINC folder to log on).

I can also see than your computers are having a lot of errors on results. This is worth solving...
Are you overclocking?
Any cooling issues?
What antivirus solution are you using?

It\'s a bit difficult for me to hear-understand some parts for first two presentations even on external speaker...partty due to my language limitation.

Third one is fine...haven\'t watched others yet.
6) Questions and Answers : Windows : User average not changing (Message 23958)

Looking at your host results, there are huge number of model\'s crashes.

is your machine overclocked?
overheating?
what antivirus solution?

I would first suggeste to deal with problem of machine stability and/or crashing models.
It would be also good to upgrade to latest BOINC version - 5.4.11

Credit is based on trickles uploaded. Some models were not running long enough to rech and upload upload as least one trickle...which is why you got zero credit for such cases.
But the are obviously models that lasted long enough to reach some trickles, which you should have been credit for, I think...

Hi,

I would simply download latest version on BOINC; generation 4.x is way outdated, use 5.x instead.
8) Message boards : Number crunching : How forgiving would climate be to changing operating system mid-WU? (Message 23135)

Yes, thanks for the observations.
I still think there is actually no need for 32-bit BOINC (core/manager/studio/view/whatever). As BOINC communicates via sharing memory/DLL and doesn\'t need much memory (10 MB will do) and it doesn\'t perform any calulation...why 64-bit?
But it needs ability to report \"I\'m running on 64-bit capable CPU + OS).
What we \"need\" is 64-bit BOINC applications...

It is still beta so memory usage may change (hopefully) before gold version.
I agree it will be more demanding than XP - perhaps twice as much as I\'m used to with every next egenration of OS from M$.

Even nowadays, one can use 2GB for hard-core gaming (not mentioning graphics works, rendering etc. where it was commong even years ago).
The trouble with M$ and 32-bit always was and still is: it can\'t use 4GB. So, where 2GB for Vista + latest high-end high-resolution with high-details game titles might not be enought to run smooth, 4GB is not an option as it can\'t be fully utilized with 32-bit Vista (or XP SP2). I\'ve been trought this so I know what I\'m talking about.
To lower memory usage, I have disable (actually removed from installation) redundant services and applications like remote desktop, M$ Outlook Express and many more...

A 64-bit version of Vista looks like a solution (and XP x64 did the job for me as well). Still the drivers availability is kind of precarious - for example for my HP BI 3000 DTN - a $1000 piece of hardware...not a $50 crap of looks-like printer.
Hopefully, when Vista goes live, HP will make proper drives if they were unable to make them for XP x64.

Anyway, for now, I don\'t see much benefit running Vista in a near future.

I had no trouble *running* BOINC on Win XP 64-bit nor Vista.
But installing, resp. attaching to the projects may be different issue.

On Linux, 64-bit version may try to download 64-bit app.
Issue of 32-bit app and 64-bit OS is being discussed on BOINC dev. list.
BOINC is not ready for 64-bit - at least in term of reporting 64-bit availability (both on OS and CPU level).

But once you get it running, transfering to another Win OS should be trouble free - 64-bit runs on WoW emulation (without effeciency impact).
There is no need for 64-bit BOINC core, but reporting 64-bit OS needs some handling, IMHO.

LTD is in seconds, so Rosetta is fine, but CPDN and SETI has over 12 hours. It should settle down eventually.

re dual-cores. BOINC should be fine. I have done so several times during my regular updates (went dual-core a years ago on 3 home machines).

Hope you hget stability/sw issue solved so no more model crashes...
