I think the 6.02 app for OSX will be significantly faster (hopefully as fast as the i686 windows and linux apps).

I'm at almost 50hours for my first one and it is still showing 100hours to go. Looking at the progress bar looks like it will be just about in that range.

I've been able to build an i686 version that works on 10.4.8 (and possibly earlier 10.4).

The powerpc version has been taking longer, mainly because there are so many dependencies to build on a slow single processor PPC, it's just taking forever.

Eric

Good luck Eric you have my sympathy. I know how slow it feels every time I run the G4. I only can imagine how slow it is to compile code and then test it is.

And this morning it looks like to machine I was compiling on at the lab crashed during the night or it powered down for some reason. I won't be able to get there to start it up until tomorrow. I may have found a dual processor G4 that I can use, though.

I've got a 6.01 running on a dual G5 that's at 99.6% and should report soon.

Double check on your G5 it maybe 10.4.x capable. I think they originally shipped with 10.3 or very early 10.4. Look in the system profiler in the dock and get the machine model # and name then search apples support website and should tell you the original OSX shipped with that model. I know that some apple enthusiast websites have a list of older Macs and what versions of the OS they support.
Edit Your G5 should be way faster than any G4 based PPC Mac. I looked the second year revision of the G5 based towers where shipped with 10.3.5 and I think the 3rd and final year of the G5 based towers shipped with 10.4.2 or 3 been awhile and my google foo is weak today.
Edit # 2
Just Doble checked All version of G5 based Macs can run 10.4.x the last version was introduced before 10.4.3 was released. I just went and searched out the release press releases of both the towers and the iMac G5s. You just need a late release generic system install disk for OS X 10.4 I think Apple sold version with the following on the disk 10.4.0 10.4.4 or 5 and I think the last sold 10.4.8 on a disk but the last one may never have happened. The key being if your model came late in 10.4.x the sold in stores disks may not have the support info for models late in the run of that OS slipstreamed into the generic instal disks. However you should be safe with a disk that wants to install 10.4.4 or later. 10.4.x was the longest lasting of any version of OSX released I think it was 20 or 22 months.

Message 42099 - Posted: 2 Apr 2012, 21:33:47 UTC - in response to Message 42098.  

Unfortunately it's in use by someone else who needs 10.5 on it, so I can't downgrade. Originally it had 10.3 on it and was the closest thing I had to an OSX development machine.

Anyway, the dual G4 is proving the be faster than the single G4 I was using last week. I'm in the process of finking in the final package I need for the compile. With luck I'll have something in beta tomorrow. Of course, then it's a week to get results back.

My only problem is I have a MB running on mine will be around 20 hours after the shutdown tomorrow before that one is done. I did not want the G4 going cold while I was waiting for the new build of AP. Oh well I will grab one when done. Edit 1 The other problem is the Intel machine is running a team challenge on PG until 18:00 UTC April 3rd. So the AP on it is delayed 48 hours. Will pick a 6.02 in a 48-72 hours after that.

I have tasks running on two macs now. Any chance for OSX GPU apps? I have both nvidia and ATI.

GPU apps are the next step, but I'm probably going to need to switch over to SETI@home v7 GPU apps first and finally get them out so that can go over to the main project.

You might be able to get OSX GPU apps from the folks at http://lunatics.kwsn.net/ earlier than I have them available.

Urs is working on Optimized AP currently for OSX currently and he is the only developer doing work for OSX.

Well I tried to do a test on OS X AP 6.02 on my G4 as part of the test. I have a partially run MB on board on that system and it can't be done before the WU deadline.The server posts a message saying it won't be done in time and refuses to send a WU. What are deadlines for AP here on Beta? I will finish the MB in about 38 hours and I will see if that will allow the WU to barely fit in the window to pick it up. If not Eric sorry I won't be able to help you test the newer version of AP on an old G4 on OS X 10.4.11 system.

Edit

I think I can pick up one when the MB is done because the machine could grab one when I first set it up with a 6.01 version of the application that then died with a missing library link error.

For some reason the scheduler is greatly overestimating the run times for 6.02 (as in saying a 250 hour run will be 1700 hours). I'll think of a way to temporarily fix it before I leave work today.

Try it now. I'm not sure how long I can let it go with these settings.

It's not letting me grab any work. Am aborting the 40% done MB will try again in just a second. Got one now it just needs to download. will post in a few minutes after the download is done.

Ok still pulling the last file. Set NNT so if it fails the computer won't try to load and trash many WU. Now that the larger files are done it could do several if I don't catch it. Ok running now 27 second and no problems. waiting on the progress bar start. No immediate death of the WU like the last time. Progress bar has now started @ the 1 minute mark. Looks good for the start. will post when done or on error. So far so good.

Edit the WU is claiming a run time of 981 hours on a 800 MHz G4 single CPU machine.

The AP is now in High Priority mode and will stay there for awhile.

edit

Looking at the CPU usage it is really saw toothed. The CPU runs for 30-40 seconds at 100% and then it drops all tasks running to 3% and then 1-2 seconds later it is back to 100% for 30-40 seconds. Is this the 100 MHz frontside data bus starving the CPU of data so you get a 1-2 second cache refill every 30-40 seconds?

I think the low CPU period is probably during checkpoint writes. The fold buffer is about 2.5MB in size.

Now we just need to be patient and let the results come back. We've got one normal (full run time) result for 6.02 Darwin Intel at this point. When I've got about 10 I'll consider promoting it to the main project.

Just a hint @ the run time for 6.02 on a G4 800 MHz 4.8% done in 14h 25m = 300h 20m if progress is linear. Now faster machines will give faster results I hope mine is one of the slower PPC machines(I would hate to see a slower machine).
