If a tree falls in a forest and there is no one there to hear it, did it really fall?

Of course it did - that's in the definition. But did it make a noise?

F.

A tree in an atmosphere will always make a noise when It falls, Even when Humans are not there. It just means a Human wasn't there to hear the sound, Animals were there and did hear the sounds the tree made as It fell to the ground. As a tree in a vacuum will make no sound as a vacuum can not transmit the vibrations that air will transmit to Your ears.

I didn't, As It was already petrified and as such can fall like a rock which since the tree's petrified, It's already dead and not living, As to how It got there, Somebody brought It there I'd think.

A petrified tree in a vacuum? No wonder it fell down!

ROFLMAO, you guys.......

It was knocked over by Surveyor 1 which crashed into the Lunar surface back in the 1960's, As to Who brought the tree to Luna, It must have been ET(Not of the Movie), As the Astronauts didn't have that much room for that piece of dead wood in their space craft(weight limits).

Sorry by my ignorance, but ... What does 'cpu affinity' in BOINC?
What is the improvement vs 5.10.28 in this feature?

Thanks!

Sorry by my ignorance, but ... What does 'cpu affinity' in BOINC?
What is the improvement vs 5.10.28 in this feature?

Thanks!

On multiprocessor machines, if enabled in the global preferences, BOINC core client launches as many project processes (WU's), as many processors are available (or allowed to use). Unfortunately, the official client currently does not assign each process to a specific processor, and hence Windows spreads individual threads of the process among all available CPU's. In some cases, when a task intensively uses the L1/L2 cache, it can lead to loss of performance due to the CPU change and cache misses.


I 'snitched' it from truxofts homepage..

...
If I remember correct, Josef W. Segur said, if you want to be sure that the upload and report of the result will be written well at the server you must have 0.002 days (~ 3 minutes) between that..
...

When Keith noted the apparent relation between reporting quickly and validate errors in the SETI Beta forum, I suggested the 0.001 day setting because it is easy to remember and seemed long enough that any possible server delay would be over. It seemed to help, so the word spread to the community.

As I recall, you were having validate errors here while using Crunch3r's 5.9.0 and reporting immediately, then switched to 5.10.13 and the 0.001 setting but still got validate errors. You were wondering if 0.001 might not be enough, so I suggested changing it to 0.002 just in case that might help.

Of the reported cases where a validate error has been correlated with work fetch causing a report fairly quickly after an upload completed, I don't recall any longer than 22 seconds, but the number of times users have checked has been small relative to the number of validate errors. As an old engineering type I'd choose a larger safety factor than Crunch3r has, but the one minute is almost certainly enough.

                                                                 Joe

I'm sorry!

..you see, I'm going old.. ;-)

However.. Y'all wanna have the 32 bit client too ?

Oh, yes, please!

Sooo.. it all depends on what "PILL" you choose on my page...
(maybe tomorrow i'll upload the 32 version of the client)

we'll see if i can find the time to do so ;)

Of course, a lot of people would happy if you would publish a 32 bit client!! :-)

Crunch3r has release 32 bit BOINC

Thx a lot, Cruch3r. :)

You are using opt. app Rev. 2.4 without V
I think it would not give you more performance, but with V you could run this app with WinVista
and you have then the variable credit multiplier.

You can get it from Crunch3rs homepage too.


You have the Core 2 Duo Processor.. so I don't know, if 'CPU-affinity' would give you more performance.
Because it's one CPU.

For example my Core 2 Quad have 2 Core 2 Duo, so it could give more performance.

And if you have a mobo with 2 separate CPUs, it could give you more performance too.

But you could test it, and tell us your experiences.

@ Josef W. Segur

If I remember correct, my 'validate errors' were all the time the 'no command' errors. And finally I think it had nothing to do with the time between upload and report.

We had a long time to solve this problem. ;-)

Finally I think it's a problem with the firewall.

Sometimes I have this problems again.

The next time, I will install a new 64 bit OS, and will see then if this problem will continue.


BTW.
Thank you very much for your support in past (and in future? ;-) !! :-)

I made the update from BOINC V5.10.13 to V5.10.28 and let it run.
So the Benchmark-test was running.
Then I closed BOINC.

Then I took the files (32 bit) from Crunch3r to the BOINC-folder.
Started BOINC.

No Benchmark-test was running.
I wanted to do it manually, but nothing was going.

Now it's no longer possible to let run the Benchmark-test manually?

Only every 5 days automatic?


BTW.
I modified the title of this thread..

With my new computer that I just got to replace this one, I decided that I needed a boinc manager that would work well under Vista and I am now running Crunch3rs on it along with this worker.

Thanks Sutaru. I know.

I'm runnig now 2.4 SSE3 from lunatics becouse I have win32xp and I don't need Vista compability.

I was crunching with the 2.4V SSSE3 from Crunch3r since september when he publicate it. As the multiplier that contain the WU's, now is always the same, I don't need (by the moment) this feature. Since Nobember I'm testing 2.4 SSE3.

And I think the 'affinity CPU' could works with my CD2. I think the 'affinity' is by 'core' not by 'CPU'.

Now I'm going to get Crunch3s BOINC Win32 version and test it.

Best Regards Sutaru and Thanks Crunch3r.

Well... Now is runnig...

Sutaru, the affinity works! windows task manager shows affinity only for CPU 0 or CPU 1 (cores) in the two tasks what are runnig (yesterday the two task shows affinity for both CPU's).

But there are sonmething wrong in the benchmarks...
