Here's a case where my wingman and I produced different results for the same WU, but both were deemed valid. Can someone explain why this happens?

Not an original explanation: The Scientists get the one that has done most (well really both go directly to Harvard). The validation in this case is considered sufficient when the 2 results have match on the part that the slowest wingman did.

The validation in this case is considered sufficient when the 2 results have match on the part that the slowest wingman did. But this situation is different from that. There was no "slow wingman" here. The machine that completed only 3 of the 16 jobs exited in less than 1 hour. That's what has me puzzled. |

Exactly as what I explained and understood, yours is then the one that has the scientists interest having done the most. Why some tasks do early exits I've not heard, neither what RC = 0x4 or RC 0x100 means. Let's see what techs or scientists have to pitch in on this. Then we can start collecting some of the bits into the "don't worry, these are benign messages" FAQ. Depends on how long this phase will run.

I haven't seen an update to this question anywhere else. Sekerob, can you tell us what happens when both crunchers don't finish the WU (due to whatever reason)? You have already stated that the scientist care about the one that did the most work, but what about the parts that aren't done yet? Will they figure out what WUs haven't been done and recompile new WUs with the unfinished parts?

That will probably be taken care of in "child" WUs as in other projects.
I do not know that for a fact in cep2 but assume it is true as I have gotten a few that were surprisingly short running, both for me and the wing man (around 4 hours). The rest are running 6 hours and up. I have only had one time out so far. Happened a couple weeks ago. |

There are no child results created FAIK. The tasks have series of dependent jobs (simulations) one taking the input of the previous or root. Why in a quorum sometimes one computes more than the other I don't know, but the validation process is set to accept that and to move on as defined by the scientists.

Just curious. And still no answer by some scientist found. :-(
I have some WUs where I finished all 16 jobs successfully while my wingman had 'Application exited with RC = 0x100' e.g. within job 12 and was skipping all succeeding jobs, but both tasks validated without problem. On the other hand if the wingman has 'Application exited with RC = 0x4' his task becomes inconclusive and then invalid. Not a real problem, but I'd appreciate a scientific explanation for both return codes and their difference. Or did I miss something? |

I can't get any CEP2 WUs to finish on a Athlon XP rig running Ubuntu 10.04 with all updates. All units fail with RC = 0x4. Could this project require SSE2 cpu support? I had another rig with a P4 HT cpu that did not have this problem. Just looking for some information before sending the box to the scrap heap. Thanks.

My wingman has an error I haven't seen before; thought I'd post it in case it's not already a known one. (His result was declared valid, by the way, as was mine which ran correctly all the way through to the end.)
