Can anyone help me with a major Einstein problem I have?

Basically every task I download immediately reports computation error!

I completely reinstalled my pc this week getting rid of three crappy hard disks and replacing with a pair of 500Gb SATA drives. Now running Ubuntu 8.04 64Bit and Vista 64 bit.

Installed Ubuntu without issues as before but am now getting this problem with Einstein. WCG and Rosetta work fine so I am very confused. Tried a manual install with the .sh script and also installed via Synaptics manager but both give me the same result. Any ideas? Or any ideas where to investigate or what log files to look at?

Not too fussed just now since will just stick with WCG and Rosetta just but really want to sort this since I was racking up a nice amount of credit running Einstein on Linux.

I am not over clocking. I saw this problem once a few weeks back when pushing my q6600 to 3.15Ghz but back at stock 2.4 now so really confused. I thought it may be a permission problem but surely all projects would suffer same result?

An example task result is this:

Any help is greatly appreciated.

32 bit libraries?

If I recall Ubuntu64 doesn't have them pre-installed and a number of apps require them on 64 bit distro's. Try use Synaptic Package Manager to install ia32libs (or similar name).

Trouble is you may have used you quota of 16 WU for today, so if necessary, after installing the 32bit libraries, disconnect and re-connect to force a new installation and download a new batch of WU.

Good luck!

I've tried to search for the 32libs but synaptic Package Manager cant see any, probably my fualt for being a linux greenhorn

meely-mouthed get out clause: the following was taken from an Ubuntu 7.04 Live session, it may be different on the installed version.

In synaptic package manager, search for "ia32-libs". It will probably find several dependencies that need installed alongside.

Still not sure if that was sneaky's problem, but it's worth a punt.

It worked!

Cheers Nightlord for the good advice. I would have really struggled to get this going myself.

I just searched for ia32 in synaptic package manager. I installed ia32-libs and dependencies and it all worked.

I didn't to do this the last time I installed Ubuntu but maybe I installed something else that required these package.
Anyway one to remember for future issues.

Thanks again.

Just noticed that I have a lot of "Validate Errors", I take it I won't get any credit for these? if not, I've lost a load of time and credits because of the einstein server crybaby

just discovered this post on Einstein@home - they have server/upgrade issues just know ..

Nightlord · Posted: Mon Aug 04, 2008 5:34 pm Post subject:

The Einstein server upgrade work should be completed today (according to their plan last week). As I type this though, I'm still having upload problems. It'll work itself out, then think of the credit Cool

......unlike Cosmo that granted me zero credit for many hours crunching just because my wingman happened to be assigned the new app while I was assigned the old. Apparently new and old apps are not compatible. I think it was about a dozen or so WU's across a range of boxes, each one lasting several hours each before I pulled the plug. Will check back in a few weeks. Evil or Very Mad

The server is up and I finally managed to report all the WU's, but there was a hiccup during the migration process. For several hours there was a problem with uploads that trashed WU's. SO far I've lost 16 Sad

OK, so this has been a very stable and responsive project. And the project lead scientist personally comes to the forum to apologise (see here). So, I'm prepared to live and let live. At least there is feedback, rather than a deafening silence such as you get from other projects that trash your WU's Rolling Eyes

and see here for the new credit [issues?]

http://einstein.phys.uwm.edu/forum_thread.php?id=6806

http://einstein.phys.uwm.edu/forum_thread.php?id=6802

the basics, OK on 1 result only! ...

Linux

old = 4 hours 237 points given = 59 points per hour

new = 6.3 hours 192.24 given = 30.51 points per hour Rolling Eyes

50% less

Mmm, there's a pattern emerging here what with an even more brutal "correction" on cosmology and rieselsieve going offline. The good payers are being reined in/ self-regulating and we are in serious danger of WCG being averagely rewarding. Of course it's how Boinc should be but a bit boring. Sad

I've not posted about this over at Einstein for fear of being black listed or otherwise condemned with sideways glances.

But here I think I can speak a bit easier.

There are two things that really annoy me about this whole credit adjustment......

Firstly, there appears to be a small group of people going round each high paying project telling them to decrease their credit rates, but I see no evidence of the reverse - pressure to increase badly paying projects.

Secondly, projects like Einstein have just converted over to using "optomised" science apps as standard build, yet they are compared in the credit rates with stock apps at Seti. It is clear to me that if I wanted to reach a high project RAC, I will have to go back to Seti and run optomised apps.

There are a few alternatives, I could go back to ABC and run true 64bit apps that crunch twice as fast as 32bit, or I could increase the commitment on GPUGrid (PS3Grid). Meanwhile, I'm pushing on to 1M on this project while looking at QMC and Milkyway.

The puritan tendancy is a bit irksome. As you say it's all about reducing credit rather than equalising it. Sad

On the whole though this Boinc credit crunch is a good, if rather boring, thing. If each project was always trying to be more generous than every other one, and got off with it, then we would have run away inflation, Zimbabwe style, and soon our hard gained 92 million amassed over 4 years would be acheivable by a low end laptop running Cosmo@home for an afternoon. Shocked

Anyhoo I'm going to use my belated discovery of the optimised Seti client to get my Seti million, boost my RAC (and that of TSBT) and delay the inevitable serial demotions which are my future prospects!
