Do not use 2.0 apps for core 2 duo.

Please, note that SSE3 is different from SSSE3 (it's not a mistake in "s" numbers).

2) use again the invalidated results - whan the problem is solved - and assign value to the user, because them are correct results.
This I think is "not waste our work". Bye,Franz

So you are saying that your pc is wasting time because you are crunching and not getting credit for the work done? If you are not getting any credit, then none of us are. This is not a pick on Franz thing. Sure it needs to be fixed, but recrunching a unit just so you and I can justify having a ton of computers on our account, is not the way to go IMO. You and I, and lots of other people too, have more than just a couple of computers crunching for Seti. That is our choice, we can put them on other Projects, but for me I do not. Seti should not change the way they do things just for us.

Thank you Franz. I was running it already, but I had never heard it called the "lunatic optimization"!

BTW, I checked out some of your crunchers, and I noticed that your E6600 is running faster than my E6800. Somewhat surprised by that - any ideas why? I do notice you are running BOINC 5.5, whereas I am running BOINC 5.4.11 - would that make a difference.? Where can I get BOINC 5.5?

TIA,

ok, now my two cents!!

Somebody (i think it was Intel) Donated servers to SAH Recently /// Are they online? and if so were they added to the collective or just being used to replace others?

My next remark is WHY are all the servers located at ONE Orgin ... they need to be scattered across the The DNS roots or at Least One on each coast, In the US of course and WHY hasn't berkeley Asked or included other Universities in this ....they have servers, bandwidth and resources that are desperatly needed here ... SETI has outgrown UC Berkeley and needs to diversify if it can continue without issues that have been seen in the recent past.
Just my humble opinion.

From the Technical News of 2006 section "And finally an addendum to the addendum in the previous tech news item: The Intel donation is in fact a quad dual-core Xeon processor system. Turns out only half the processors were coming on line, but were hyperthreading, making it look like 8 total processors. After some tweaking in the BIOS the system finally recognized the other two processors, so now, with hyperthreading, there are 16 3GHz processors according to the OS..

December 5, 2006 - 23:15 UTC
Today we had the usual database outage a little bit later than normal (the person who usually does this was out sick today). Nevertheless, it was short enough that it still remained within our claimed 4 hour window.

An addendum to the previous tech news item: The recent Intel donation is not a quad dual-core Xeon processor system - it is a quad single-core Xeon processor system using hyper-threading (which shows up as 8 processors according to the OS).."

You missed this in the December 8th posting:

BOINC version 5.5.0 has been banned at a few projects for overinflating benchmark scores. So don't take it's numbers seriously.

Sorry, I didn't know it.
I use it because it send immediately the results, after the upload.

Boinc 5.5 (exe & dll) was a Crunch3r optimization, if I remember well, so it's no more available.

Please, note that SSE3 is different from SSSE3 (it's not a mistake in "s" numbers).

Actually i don't know if anyone ever noticed that, but the SSSE3 app. does not allways calculate correct results and/or misses some signals from time to time.

here's an example (taken from Francescos Core2)

WU: http://setiathome.berkeley.edu/workunit.php?wuid=108740479
SSSE3 result http://setiathome.berkeley.edu/result.php?resultid=454501525
SSE3: result http://setiathome.berkeley.edu/result.php?resultid=453729504
----------------------------------------------------------------
WU: http://setiathome.berkeley.edu/workunit.php?wuid=109443175
2x SSSE3 INVALID

Compare the signal counters on the first WU and you'll see what i mean.

On the second WU both Core2 apps got invalid results.

Wonder if Ben or Simon know about this.

mmmmm mumble mumble ... I have seen it.

It's better to isolate that workunit as soon as possible and test it.
Normally the results from SSSE3 are valid!.
So there must be something in this workunit.

But this shuld be discussed in a different thread.
I think.

Well that's not an issue of the WU, it's the application that misses signals and as long as there are not too much missed, the validator grants credit for it.

The SSSE3 app is version 1.41, and we do know that its results occasionally are only "weakly similar" and even less often may be invalid. See my post 5 days ago in the "Error in Credit" thread for the explanation.

That version continues in use because it produces a higher RAC for Core 2 systems than version 2.0 builds, indicating that the few invalid results are more than balanced by higher throughput.

Franz, errors happen, that's life jim but not as we know it.

There is nothing that can be done to stop them.

CAREFULL, he will tell you to "Please use better your brain." I tried to tell him many messages ago that it might be the Optimized version and got 'yelled' at.

Well i guess you're refering to that one:

It's not a problem of optmization (Yes, I do it) or overclock (No, I don't).

It's a general problem.

When the validation happens, everybody fall!
Indipendently from optimization.

Please use better your brain.

And indeed it's not a problem of optimization that caused the validation errors, at least not the regular ones that you can get if you're using the core2 app, which i guess delivers somethines more than "week similarity" it's more like "very week similarity".

Validate errors is becoming a rule, day by day.
Once sometime is possible; more is diabolic.
Please investigate and solve the problem.
ASAP.
Or we'll find other projects.

Ok, SATAN, this is a big gift of philosopy! Thanky you.
Now I'll sleep fine :-)

Of course we fight every day to have better solutions against errors, knowing that behind every solution we'll find new errrors.
This is humanity's story.
But a million years ago we were in caverns, now ... we are crunching!

Isn't it?

I think you may have interpreted my last post incorrectley. All I am trying to say is that, errors are going to happen, nothing is perfect. Granted I am sure all of us that are running S@H and all other project would like it to be error free.

But complaining about it will not achieve anything. The only thing that will help is to give money. I am not financialy able to do so at the minute. However if my situation changes I would make a donation to the cause.
