Got home from work today and found this Task on one of my G4s. It is flagged as v6.04, with a hugely over-long estimated completion time of 166 hrs (vlars normally take this box about 40 hrs), and a new entry in the Details section for S@H v6.04.

Is this a new ap version, or a glitch? If a new ap, what changed?

It looks like it's a new app for Mac OS/X 10.3+ .
http://setiathome.berkeley.edu/apps.php

AFAIK, after 10 granted Cr./WUs with this new app and the estimated times should be again correct.


But little strange..
If this overview is correct, this app wasn't testet at SETI@home Beta Test.
http://setiweb.ssl.berkeley.edu/beta/apps.php

So maybe it's a mistake.

Or maybe only a cosmetic modification of the app.

Oh, joy! That means my other G4 will get its first 6.04 on Thursday. 10 tasks will take about 2 weeks for either box, unless we get another shorty storm.

Well, at least the current estimates are too long, rather than too short. Plus, each validated task should start scaling the DCF back to where it belongs. Just gonna be fun to watch for the next two weeks.

Ohh.. or was this 10 granted Cr./WUs and the following Cr./WU are correct?
Yes I guess this is correct.

Because of the estimated times it will go down slowly, independent of granted Cr./WUs.
Every time a new result, the estimated times of the WUs go little down.

So maybe it will last some days/weeks if the estimated times are again correct.

Sorry, my mistake.

BTW.

You are an advanced SETI@home member?

You know there are also optimized applications for MACs available?

(Message 1112592)

Hmm.. maybe currently they are outdated.
If stock 6.04 is really different compared to 6.03, someone will release quickly also updated optimized apps.

There were no new commits to the SETI@home Enhanced source code so I think it's probably just a rebuild using a more recent compiler than the 6.03 version.

They did try to build a 6.97 SETI@home v7 Mac application for SETI Beta, but the currently supported Apple version of GCC doesn't have support for AVX code so they left the earlier 6.92 in place there. Last time I looked, Apple had GCC 4.2.1 but at least 4.4 is needed for AVX. It's a puzzle that Apple is producing machines with Sandy Bridge CPUs but doesn't support the new instructions yet. That would only apply to Mac/Intel machines of course.

Beware of the bolded text, as you said the client side dcf will go low, maybe v. low, before 10 tasks are validated and the server side estimates are corrected. At that point the server will possibly give the correct estimate, but the local dcf will then lower those estimates. The net result could be d/load of hundreds of tasks.

Yes, that is one thing I'll be watching for, but I doubt I have to worry about hundreds of Tasks with too-short estimates. These are 10-year-old mac G4s, not relatively new i-5s, and my caches are set to 0+4. Maybe I'll change that to 0+2 until things settle out.

Don't be too sure, on my quad which I recently had to rebuild, I also installed Win7 at same time, the client DCF went down to 0.087 just before server side estimate for GPU tasks kicked in. Some of the DCF reduction was because Seti servers were off-line for a few days at the critical period.

Looks like Apple is not going to support the newer builds either as they have changed to clang as the supported environment.

Charlie might want to look into Macports instead. They have GCC up to 4.6.1 currently.

Or what is the problem here?


[EDIT: The app overview say this new 6.04 app is for OS 10.3+, why get lower OSs this new app? They should get 6.03?
Why make the app with OS 10.5 and 11.1 errors?]

I'm not sure of the issue with the "failed: errno=88". However the oldest OS I see there is Darwin 9.8 which is MAC OS 10.5.8
Darwin 9.x = 10.5.x Leopard Darwin 10.x = 10.6.x Snow Leopard Darwin 11.x = 10.7.x Lion

It is sort of like converting 12 hr time and 24 hr time. Darwin version -4 = MAC OS version.

Ahh.. thanks for translation.. ;-)

I didn't know that Darwin 9.8 mean 10.5 MAC OS.

I thought if there stay 10.3+, then 9.8 is smaller.. ;-D


For example, Donald's (OP) PCs have Darwin 8.11, this is also 10.3+ MAC OS?
[EDIT: If I calculated correct it's 10.4 MAC OS. ;-)]


Hmm.. but I guess there is something with 6.04 if 6 MACs don't like it..
I know one more MAC because of an other thread in Q&A: 'Computation Error - Message 1150480'.

Here is another one to look at
http://setiathome.berkeley.edu/workunit.php?wuid=814725863
I have the _2 Task, it will start on Saturday 09 Sep 2011. I am running Darwin 8.11.0 = OS X 10.4.11 (missed the upgrade to 10.5), we'll see how my ancient G4 handles it.

If the new app is buggy I might have to fire up the Mac's at work to help out. Currently I just have these machines in the lab:
Dual G5 Power Mac, with MAC OS 10.3, 10.4, or 10.5
Core Duo iMac, with MAC OS 10.4, 10.5, or 10.6(x86 only)
Core 2 Duo iMac, with MAC OS 10.6 or 10.7
I can run any of those configurations if need be. I don't normally run BOINC on those systems anymore since it was a bit of a hassle with how we load OS's for test.

Well.

The VLAR http://setiathome.berkeley.edu/workunit.php?wuid=788127643 with the 166 hr est. run time that got this thread started, completed in 36 minutes, with a -9 result_overflow, but it validated against a Wintel cruncher, so I'm not worried.

That box (iBook G4) also completed this 0.74 AR Task http://setiathome.berkeley.edu/workunit.php?wuid=815237216 in about 5 minutes with a -9 result_overflow. We'll see if it validates.

Ditto here. Both my macs started to generate these errors with 6.0.4. I'm having a horrible time trying to reset the project too now. I have two macs both running the current Lion, 11.1.0 and 11.0.1 on a iMac i7 and a mac mini 2011 server i7, respectively.

I currently suspended the project on those two machines. I'm going to try the optimized application route for these machines. I just did that for my Windows machines.
