One of my machines has stopped grabbing units from SETI and Einstein. The only other project I'm running is SIMAP, which is assigned half time, but for the past three days it's the only project running in BOINC manager. Same behavior after quitting app and restarting machine. Any ideas why only one of my machines would do this?

What exact values have you assigned as resource shares for each of the projects? What are the affected machine's prefs for 'Switch between applications every...'? Are all your machines crunching all three projects? SETI working fine here; can't comment about Einstein.

I have two machines, each with resource shares of SETI:100, Einstein:100 and SIMAP:50. They've both been crunching all three projects, but my G4 suddenly stopped grabbing work units for SETI and Einstein. Preferences are default for both machines... "switch between apps every 60 min."

Try resetting each of the projects.

I agree, resetting looks like your best option. Seems like all your settings are OK...

I just had a weird SETI-experience myself: on a DP G5, I had one WU crunch for over 600 (!) hours before I noticed it and re-started BOINC. Interestingly, the WU completed fine and quickly thereafter, showing a normal WU CPU-time. All the while (i.e. during those 600+ hours), the other active thread kept crunching properly. Strange...

I've seen this too (DP 2.5 G5); occasionally a unit will keep crunching forever but make no progress. Suspending and restarting the unit clears it. (or killing the seti worker - it automatically restarts). They've all been recent - within the last 2-3 weeks, maybe a total of 4 times now. Becuase this also increases the interval at which a machine reports units back to HQ, I've taken to checking my machines on the seti accounts page daily to see which haven't reported for 48 hours or more, this seems to indicate the problem has occured on that machine.

Resetting doesn't help. The messages say "resetting project, rescheduling CPU-exit tasks" -- but it's not downloading any new work units for SETI or Einstein.

Did you check the settings in the 'Activity' dropdown menu ?

The only problem is that the authors don't explicitly mention OS X support, and if I thought remotely testing/debugging Intel binaries was hard, getting this working can't be any easier. Also, not everyone is going to have the kinds of graphics cards that will actually be useful for this.

The GPU possibilities indeed are exciting, but call me a die-hard and the eternal optimist, but I really believe the rumors of the death of PPC are grossly exaggerated...at least in the context of S@H crunching (reminds of the scene in MP's, The Holy Grail)

I was just checking for some recent updates/articles re: compilers for CBE (Cell broadband engine).

Came across this:
Sony Computer Entertainment Inc.
linuxoncell-GNU

If S@H can be run on PS3 (or any CBE server blade/PCI-E board (Cell Broadband Engine (BE) Processor Solutions) , it may be the crunch-box of all crunch boxes to beat.
At @ $600.00, there are probably quite a few of us who'd "pony-up". Heck, I might even play a game or two finally.

GPUs are exciting, but THIS could really be a coup d' etat over X86......and by PPC.
Can you imagine the stir this would generate the first time a CBE cruncher appeared on the Seti computer list.
Oh my!

Alex: Is this just a fantasy or is there enough software already available for this to be possible?

Activity drop menu has run and network activity based on preferences. All my project prefs are set to the defaults. I haven't changed anything on either machine, I'm not sure why one is behaving differently. Could it be that SIMAP is racking up too many WUs so when SETI and Einstein check in, they don't have any room to schedule.

Set the activity to 'run always' and 'network activity always available'. Just highlite it and clik your mouse so a tick appear next to it. See if that makes a difference or not.

Hi Karl.
VERY interesting. The interviewer was rather lame, but the comments made by Cell's Proj. Mgr. about "running Linux and other STANDARD OSs...was revealing. While the monitor used in the rendering demo was a Mac display, I'd assume the demo was running on Linux. Do you think same? I also read a couple of days ago that Yellow Dog will offer a Cell-compat Linux distro.

Cheers!

Didn't help. Should I try to delete my .plist or something?

Thanks for sharing this, Karl! Can you imagine SETI @ 40x G5 performance?

That would make one hell of an upgrade card

Last try, is to make sure your prefs are set not to high - not to low viz memory and disk space etc. If you uninstall, get it all, use spotlight to find the files, then start over again with a fresh install of the latest version.
