Where are the Intel Macs of this world?

We are in need of some Macs (intel). More than enough windoze up to now :-)

BTW I see that the graphics button is greyed out is this because mt 3 ghz Mac Pro has the x1900 video card rather than the standard one? it seems to be the same for all 4 of the Data units that I just started crunching... not wqanting to sound selfish but a big part of the fun of these projects for me is in 'seeing' my computer actualy do something with the data via the graphics window...

I have suspended Einstein and Seti and the IBM cancer projects for 24 hours to give your project a good start after that it will get 25% of the time and share with the others

Cheers and good luck with your research

Hi Randolph,

We don't have a screensaver yet, but are working on it. It has been kind of pushed to the back of the todo list because of the many problems we have discovered with our app. See many other posts if you want to have details on this.

Thanks
Andre

WooHoo! In a week or so I should be adding a new MacBook Pro (Core2Duo) to the mix. (Tax Man overdid it last year, and is sending me back some love!)

I wish father Tax Man was as good to me as to you :-) Congrats!

As a side note: I have been able to reproduce the problem where a mac delivers different results for the same workunit. It only happens when the app is interrupted a lot (e.g. by the boinc manager to run other projects). We think checkpointing has something to do with this and are currently researching this issue. Hopefully we'll have it solved soon!

Hi,

yesterday I have added 6 Intel Macs (MacPro 2x Dual Core 3 GHz).

But there is not enough work for all my 6 Macs.

Hmmm, that is certainly interesting. There are currently 345 workunits in the shared memory reserved for Intel macs. I will investigate why you don't get any and get back to you. Might have something to do with the new host identification string that the new boinc client returns to the server and thus messing up our HR rules.

Thanks for letting us know.

No, that is only valid for replicas of a workunit: the same user won't be able to get more than one replica of a workunit.

Is it the issue where the same "owner" can't get WUs issued to his/her other machines?

Only that we are still working on the checkpointing issue and have not found a good solution yet. If we can find a good solution for this problem, we should be able to go to our beta test phase and get a lot more machines involved.

Thanks
Andre

Andre, do you have some news about the MacOS application ?

Yes, if you are asking this much work, then that is the answer. You might set your work fetch period a little shorter, so you won't get the 'no work' message so often. Of course when we get some more macs on the project, the throughput will be greater as well.

Cheers

Perhaps this could be the solution of my "problem"

One Wu last ca. 1 hour 40 Minutes and 4 WUs each Computer runs togehter. That would be each computer need 58 WUs a day. In my preferences i fetch work for 3 days. This would be 174 WU per computer. My 6 computers try to get yesterday 1044 WUs. This first 2 get each about 170 WUs and the others about 40 ... 20 and so on.
Perhaps this could be the solution

Wow! Somebody's been busy the last couple days! I've gone from over 5,000 pending to only 3,000 pending! Sweet!

Yep. Frank down here in the forum attached 6 macs a couple of days ago. In one way that is good to get the pending credits number lower, but it is bad, because the pending list of mac results in the shared memory has gone up dramatically and since we don't have that many active macs, it might take a while before this goes down again.

Andre

Yes the list of mac results is now huge all the time. Those 6 macs own a lot of the shared memory segment lol. I think this new thing with WUś being able to be issued to the same cruncher but on different hosts has to help here. Even Linux/Intel doesn't come close to this many WUś reserved

Frank, how do you get the speed out of BOINC? You're consistently putting out more than double the workunits that I am. You're processor is only slightly faster, so I can't figure out how you do it. Would you share how it's done?

@ Frank, Did your MACs stop getting WUs from the queue in shared memory? There's 362 WUs and they've been there for awhile.

Frank mentioned to me that he is still crunching, but doesn't get any work anymore. So that means we'll have to check what's weird about these tasks. What I've found already is that these are actually quite old results send out because the rest of the workunit is inconclusive; why Frank doesn't get them I don't know yet...

I didn't make anything. I'm using boinc_5.8.16. The macs have 2 prozessors with 2 cores, therefore each mac crunch 4 WUs at the same time. The crunching time is about 1 hour 36 minutes per WU.

Andre, do you know if 1000/day is normal for my MacPro?

Hello John,

I don't know much about MACs (somewhat out of my price range), but I can think of a few things that might cause the difference.

1. You have Xeon 5150's at 2.66 GHz and he has Xeon 5160's at 3 GHz. BTW, I just checked and other than the clock speed, the specs on these are

64 bit Support: Yes
FSB: 1333MHz
Hyper-Threading Support: No
L1 Cache: 32KB+32KB
L2 Cache: 4M shared
Manufacturing Tech: 65 nm
Multi-Core: Dual-Core
Processors Type: Server
Series: Xeon
Vista Ready: Yes

2. The newer versions of BOINC are very sensitive to the amount of memory and swap space being used. They will pause processes if they detect that the limits are being exceeded. I've seen a good explanation of this but I'll have to find it again. Depending on the size of your swap file and how much else is going on in your systems, this might be it. BTW, what do you each have in your BOINC general preferences for:

On multiprocessors, use at most ?? processors

Use at most ??? percent of CPU time
Enforced by version 5.6 and greater

Use at most ?? % of page file (swap space)

Use at most ?? % of memory when computer is in use
Enforced by version 5.8 and greater

Use at most ?? % of memory when computer is idle
Enforced by version 5.8 and greater



3. I don't know about the x86 Macs, which I think are based on some form of unix, but I was surprised to find a thread on the BOINC forums that says that Linux CPU clock governor (powersaver) ignores processes running with the lowest priority, including project applications . The thread is titled "CPU Clock Throttling". I've never heard that before.

My guess is that #1 is effecting CPU time used and #2 is effecting wall clock time used.

Hope this helps.

Hi John,

To have a look at those settings:

1. Go to the Docking@Home website

2. On the left side of the web page, in the section titled "Returning Participants", select "Your Account"

3. On the "Your Account" page, in the section titled "Preferences", look for the top entry which says "General preferences
specify when and how BOINC uses your computer" and click to the right of it where it says "View or edit".

4. Now you should be on the page where all those settings I talked about are. There is a default set and then you can specify separate preferences for "Home", "School", or "Work". These settings apply to ALL the BOINC projects.

If you've never messed with these settings, then all your computers are set to "Home" and are using the default settings/preferences. It is possible that you have some old defaults in there. IIRC, at one time, the default setting for "On multiprocessors, use at most ?? processors" was 2 processors, but now I think it defaults to 16 processors. If it's set to 2, then you're only using 2 of the 4 cores. If it IS set to 2 processors and you change it to 4, you'll need to watch your machine for overheating since it will be running all 4 cores constantly. I don't know if overheating is a problem on MacPro or not since I don't have a Mac and all the machines I do have are single core Celerons or Semprons.

If you change the preferences on the website, then when you're finished you'll need to go back to your local machine in BOINC manager, select the Docking@Home project, and click the "Update" button in the BOINC manager to have it download the new settings from the servers.

EDIT: tried to clarify a point.

Hope this helps,

-- David

Also, the Xeon 51xx and 53xx perform much more slowly with only 2 DIMMs. They really need 4 DIMMs to get the max performance out of them. This has been demonstrated over on SETI several times now.

I am running Boinc Manager 5.8.16 on Intel Mac iMac Core Duo


I haven't run any work units for over a month.

Hello Billy,

I think those are probably very old work units that are orphaned because of changes in the HR rules and in the BOINC software itself.

The work queues are being drained, and new HR rules are being put in place. I doubt that anyone else will be able to get work until the new work units are generated. I'm guessing that the new work units will arrive sometime late today or during the day tomorrow unless a new problem is found.

Regards,

@David, Zeroing out the shared memory WUs may stop some of the questions. If there is 0 available, we won't expect to be able to get them.

Yay! The workunits are back!

Would probably be easier to wait for beta which shouldn't take too long anymore, but if he/she wants to drop us an email at dockingadmin at utep.edu that is fine.
