MacOS G5 App 4.27 available

Topic 13426
(moderation:
I've been working on the PPC code a bit more with what I learned from the coding for x86 and made a new version. I've seen it run about 20% faster than the previous 4.23 App on some machines.
However, applying all the measurements we need for copmpatibility of an "official App", this code slows down even behind the 4.23 App, at least on G5. So for now I made an App that maintains the maximum possible compatibility without loosing speed. It turned out to be a G5 App that should run on MacOS 10.4 as well as on 10.3. It is available from our Power User Apps page. I haven't seen a single invalid result from this code in internal tests.
I'll continue to investigate this level of "maximum useful compatibility" for G4 machines. For G3 I don't have any more ideas for speeding up the Apps anyway.
Happy crunching!

Sorry. There was indeed an error in the app_info.xml. I updated the package, new md5 is ecfa6c45e790b135c72587e1e2fad4ec.

Put them in the folder
/Library/Application Support/BOINC Data/projects/einstein.phys.uwm.edu/
and restart the BOINC Manager.
More detatiled instructions for such packages can be found on the Beta Test Page, look for the MacOS PPC section.

Have you actually completed a Task with the new version? Don't count on the time estimated by the Client, the estimation is based on the old App.
There are some postings in the threads here that discuss short and long WUs. See e.g. Bruce's "Information about S5" (sticky thread in Cruncher's Corner).

Which versions are these compared to, especially on the G5? I suspect it was 4.23, or was it 4.12, too?

No need to feel sorry at all!
Does that mean that the 4.26 runs 18% faster than the 4.23 on your G5? Or that the 4.27 ran 18% faster than the 4.26?
Anyway - I'm still curious to know how much faster the 4.27 is compared to the 4.26 on a G5. I'm sure that's the perfect question for you now!

Have these errors been with the old, buggy package? It was only up for ~19 hours.
You should make sure you get the new one. The error messages look like the client didn't leave you any App at all in the project directoy. Make sure you either remove the buggy app_info.xml (which will bring the client to downlaod the 4.12 again) or replace it with the one from the current package (which will tell the client to preserve and use the 4.27 App).

RE: I am soooo sorry ... It

Thank you - that's almost too good to be true.
Do me a favor and look into the folder
/Library/Application Support/BOINC Data/projects/einstein.phys.uwm.edu/"
to see if there really is a 4.26 App. The old (erroneous) app_info.xml may under certain circumstances have reported the 4.27 as 4.26.
That actually was my fault - I tested the App more or less thoroughly, but not the app_info.xml...

TextEdit should be able to open the file. However the app_info wasn't buggy for 4.28, so I think I know which one you are using there.
I have written app_infos for the Mac with TextEdit, what's wrong with saving the file (as long as you didn't modify it to break)?

RE: Is the app_info.xml

Yes.
Yes. I think the 4.27 is roughly 20% faster than 4.26 (it only runs on G5, so we can't make it the "official", i.e. automatically downloaded App, though).
You should note a reduction of the CPU times you need for a Task, i.e. simply crunching faster. The variation between Tasks from the same set (i.e. having names that start with the same letters and numbers) is about +-5%, so the change should be notable even in "worst case". If the time your machine spends for BOINC is rather constant, over a week you should also notice an increasing RAC for that machine.

To get new S5RI work with this App, you must install a new app_info.xml. Stop the client, replace the old app_info.xml with this one, and start the client again.
