Am I the only one getting -146 errors on the MacPro?

Here's my box: http://setiathome.berkeley.edu/show_...hostid=2806480

Can I do anything about it?

Are you also running SETI Beta?

My 1.25 eMac just went over 212 RAC, that is the best that I have seen from it.

Still 230 below my Dell laptop though. 1.6 Pentium M.

@zombie67: Nope. BOINC manager 5.4.9 with the superbench core client substituted and Alex's worker. On the MBP and I386Mini there's no such problem.

I'll have a second box like this up soon. Then I'll know whether it's a unit specific 'feature' (=>reinstall from scratch) or another reason to look into.

I should mention that these -146 errors occur within a big batch of short WUs resulting in -9 errors. Is it possible that the worker isn't able to cope with the format of certain WUs?

I think your problems have to do with the inability of BOINC or the worker (don't know which) to allocate the shared memory it needs. I got the same errors on certain short WUs on my Quad once I started crunching with v7.1, and they went away after I implemented this fix.

Hey, check out the SETI@home page, I'm user for the day.

Wow, 24 hours of fame. Go me.

Someone, possibly from this thread, must have nominated me. If you're reading this, thanks for the nod.

Too all Intel buddies out there...

I'm having troubles downloading WUs on Intel machines... the most I get to download on a single machine is 5 at a time, which can last couple of hours max. And this happens to all the Intel machines I've BOINC'ed at work. However, my home PowerPC iMac downloads days of WUs.

Tried re-installing BOINC and repairing disk permission, but to no avail.

Any remedies to this problem...? Coz I'm running SETI@home as a daemon and sometimes I don't have access to them to keep the WU cache filled, they might just ran out before my shift ends.

Thanks.

I'm not having any problems with Intel machines downloading WUs. I have an iMac, Mac Book Pro and Mac Pro all downloading just fine.

What does the log say?

Have you checked the "Connect to network about every......" settings in the projects general preferences. I find it best to have this set to 3 days.

For months I've had it set to 10 days, I've even set the client to "Run always", and created a separate preferences for these Intel systems.... but the systems always failed to download more than 20K sec of WUs....

halimedia · Nov 9, 2006, 10:02 AM

I have a similar situation with an Intel mini I started crunching with a couple of days ago. Its cache hovers between four and five WUs (including those currently crunching).

I'm guessing that the initially small WU-cache could be due to the fact that BOINC and SETI-Enhanced might use a combination of average WU-turnaround time and host-RAC as a metric to determine the size of the WU-cache. If this is so, it would take quite some time for the RAC to be high enough to allow for the cache to build up.

This is all conjecture, however. Unfortunately, I don't remember how long it took other machines to build up their WU-caches. Time will tell, I suppose...

Edit: I have the WU-cache size set to 3 days, and an identical mini with the same setting that has been crunching for several months has a cache of nearly 50 WUs.

Thanks for the feedbacks guys.... guess I'll have to wait...

FYI: Computer summary

My G5 is at 1,199.32 which is the closest it's been to a 1200 RAC. So it's
certainly possibly - just a little more.

Gecko_r7 · Nov 9, 2006, 11:29 PM

Almost there, Todd. Sooo close!

Pulling for you!

Maybe tomorrow am?

Team MacNN now has EIGHT (8) machines in the top twenty Hosts on Seti at Home for Recent Average Credit.

Fifteen (15) machines in the Top Twenty Hosts are Apple Mac's

Maybe Reader50 will give us a headline in the Team News page.?

Maybe Apple will give us a headline?

btw G5 owners should check THIS out

*AND* we just moved up a notch, from 20th to 19th !

If it were easier to find the Intel version of Alex Kan's worker, we could probably do even better. It was only by pure chance that I came upon it and realized that I could use it on my computer.

Index of /~alexkan/seti

He keeps all of his workers there...

He's right. If you go to our home page, and then click on Resources, and then click on SETI optimization, there is *nothing* there about alexkan's stuff. There is a bunch of dead links and old stuff. It should probably all be replaced with a single link to alexkan.

By the way, my G5 2.5 dual is currently at RAC 1214.56!
(Update - just a few short hours later 1,217.76!)
(Update 13Nov06 - still up over 1200 - 1208.18).
(Update 14Nov06 - WOW! 1,255.08!!!!!)
(An hour later! 1266!!!!)
As of 16Nov06 the highest yet - 1,284.40! (an hour later - 1288).

We will see how long it lasts up there!
