I've released setiathome_v7 for Macintosh. It's possible this version will no longer run on powerpc OS X 10.3.9. OS X 10.4 may be required.

Great!

Thanks,

Ah, good one. Now finally i can stop using my own 10.5+ version.

It just sent me the PowerPC version for my Intel iMac.
Could be a BOINC problem. Also having an Intel CPU the end of my client_state.xml looks like this :
<platform_name>x86_64-apple-darwin</platform_name>
<core_client_major_version>6</core_client_major_version>
<core_client_minor_version>10</core_client_minor_version>
<core_client_release>58</core_client_release>
...
<alt_platform>i686-apple-darwin</alt_platform>
<alt_platform>powerpc-apple-darwin</alt_platform>
...
</client_state>
powerpc on Intel CPU host as alternative platform ?

With a detach and reattach of the project, it sent first the i686 app and started running the first unit with it, then when it fetched one more WU it sent the powerpc app and started the other with that.
Something weird going on with the scheduler.

That's pretty weird. I'll go through the logs to see if I can figure out what's going on. Is anyone else seeing this?
I'm not sure why an app would report emulated powerpc as an alternative platform. Alternative platforms should only get work if the main platform isn't available.
I wonder if any x86_64 linux machines are getting i686 clients.

Please keep those Mac's on and crunching (but cancel the PPC results) so I can catch them in the act.

Good to see the SAH v7 update, but janitorial work awaits...
http://setiweb.ssl.berkeley.edu/beta/apps.php
The (dynamically generated) HTML page seems to have no indication of its last modification date.
Grabbed a couple of MAC tasks. Will let you know if I see anything strange.
P.S. Does this mean you might compile a stock MAC version for Astropulse also?

Rosetta ppc to i386 translation is part of OSX.
Also here is a technical note from Apple Developer, maybe that explains the found alternative platform and (indirectly) shows a way how to avoid it. The universal Mach-O binary in this case is BOINC.

Unfortunately, there is no way to tell which app is going to be used for the WU before they start and this one started sometime during the night.

The other 3 used the i686 app.

I'm hoping that now that some statistics are in, the scheduler will realize that i686 is a faster app.

I'm pretty sure that this was a deliberate decision to include ppc on the part of the BOINC developers, so that intel based Macs could participate in projects that didn't have intel apps. I don't know if any such projects exist anymore.

4-5 years ago that decision was of course not only logical but also comfortable. Both sides, user and developer, had the ease of a single choice. Maybe after new OSX version Lion is out, later this year, a reconsideration would show a slightly altered situation.

Is Lion removing the PPC emulation?
____________

Yes.
No Rosetta
While Apple dropped support for running Mac OS X 10.6 Snow Leopard on PowerPC Macs, 10.7 Lion will remove support for running PowerPC code on the new machines via Rosetta, a translation bridge that enabled Intel Macs to continue to run old software.
Rosetta was not installed by default in Snow Leopard, but could be installed by users who needed to run old programs that had not yet been updated to run natively on Intel Macs. In Lion, Rosetta support is gone entirely, spelling the end of the line for PowerPC as an architecture.

It's possible this version will no longer run on powerpc OS X 10.3.9. OS X 10.4 may be required.
FWIW—and touch wood!—my 733-MHz G4 running “Panther” seems to be doing OK with its first task: last time I checked it was well stuck in, on course for a fifty-hour running time. It may be worth noting that the graphics are disabled on this system. (I had to turn them off a couple of years ago, following a BOINC upgrade, when the science apps became prone to crashes whenever the screen-saver started or a graphic window was opened.) The graphics do work just fine on my “Tiger” G5.
____________
Update: that first task from my G4 running OS X v10.3.9 completed successfully (in 49.1 CPU-h) and has been validated.

Good to know that 10.3.9 is still good.
