I'm running boinc-7.2.42 on powerpc-linux-gnu and I have noticed that it's not getting new work units any more. In fact, I noticed this a long time ago but haven't looked into it until now. The last message from stdoutdae.txt was:

10-Jun-2013 06:10:54 [Milkyway@Home] Sending scheduler request: To fetch work. 10-Jun-2013 06:10:54 [Milkyway@Home] Requesting new tasks for CPU 10-Jun-2013 06:10:57 [Milkyway@Home] Scheduler request completed: got 1 new tasks 10-Jun-2013 06:10:59 [Milkyway@Home] Started download of 79_constrained_rev_3.prmtrs 10-Jun-2013 06:11:01 [Milkyway@Home] Finished download of 79_constrained_rev_3.prmtrs 10-Jun-2013 06:13:17 [Milkyway@Home] Computation for task ps_separation_79_DR8_rev_1_1366886102_23900132_0 finished 10-Jun-2013 06:13:17 [Milkyway@Home] Starting task ps_separation_79_DR8_rev_3_1370577207_2197297_0 using milkyway version 50 in slot 0 10-Jun-2013 06:13:18 [Milkyway@Home] Sending scheduler request: To report completed tasks. 10-Jun-2013 06:13:18 [Milkyway@Home] Reporting 1 completed tasks, not requesting new tasks 10-Jun-2013 06:13:20 [Milkyway@Home] Scheduler request completed 14-Jun-2013 11:22:39 [Milkyway@Home] Sending scheduler request: To fetch work. 14-Jun-2013 11:22:39 [Milkyway@Home] Requesting new tasks for CPU 14-Jun-2013 11:22:41 [Milkyway@Home] Scheduler request completed: got 0 new tasks 14-Jun-2013 11:22:41 [Milkyway@Home] No tasks sent 14-Jun-2013 11:22:41 [Milkyway@Home] Tasks for NVIDIA GPU are available, but your preferences are set to not accept them 14-Jun-2013 11:22:41 [Milkyway@Home] Tasks for AMD/ATI GPU are available, but your preferences are set to not accept them

...and this was the end of it. My system doesn't have a usable GPU (PowerBook G4), it was always using the CPU for the tasks.

Looking at all_projects_list.xml now I can see that "powerpc-linux-gnu" is no longer listed in the <platforms> tag, this post seems to confirm that.
I'm only wondering if there has been an official announcement of dropping powerpc-linux-gnu support and the reasoning behind it. Does anyone have more information on that?

I don't know about any "official" announcements, but Linux PPC isn't listed on the applications page. As an avid OS X PPC user, it's harder and harder to find work for my machine; I imagine the user base is probably even smaller for Linux?

WUprop PowerPC Linux:

Here's the projects which still support OS X PPC, fewer and fewer all the time. I know SIMAP will be disappearing by the end of this year, due to their discontinuing the BOINC side of their project altogether.

While we currently do not compile for Linux PPC, you are welcome to compile your own version of our application since it is open source. You can find the code and instructions at https://github.com/Milkyway-at-home/milkywayathome_client. Just remember you will have to recompile each time we do a new release to ensure your work units keep validating.

(On a side note this should probably be moved to the number crunching section, more people will see it there who can help.)

If you guys have any questions that aren't explained in the documentation on github please feel free to ask.
