Gandalf: Are the deadlines on these new wu's 3 days by any chance? Re-sends still are being sent it seems... which makes sense as otherwise the guy that has already completed is left in limbo This is the 13th and the deadline indicates the 16th, so I guess that makes it three days. I can only assume that I ran into a timing differential. The MCM1 WUs were halted just after the one PC had received its downloads. Otherwise, why weren't re-sends sent to my other three PCs? Part from looking at the time left and doing calculations, it is far easier ti look at the name of the WU. If it ends with _0 or _01, it isn't a resend. If it ends with anything higher than _01, it is a resend. The higher the number, the more times it has been resent   Crunching in memory of my Mum PEGGY, cousin ROPPA and Aunt AUDREY. |

Woke this morning to four more tasks sitting there chugging away on elapsed time and no CPU time. Fortunately they were all on the same machine so I just rebooted it.
----------------------------------------Hope this gets addressed when the WU start flowing again. It could lead to a lot of lost CPU cycles.  Distributed computing volunteer since September 27, 2000 |

Is there any environment commonality in these Elapsed counting, no CPU time incidences? You say you booted... did that set CPU time in motion? Is it always the same OS, version, service/user (as was found to be an issue during previous betas of MCM). When looking in with Process Explorer, properties > performance any oddities.
----------------------------------------Whilst, these 4 were repairs no doubt. What did the previous copies do? ATM, the present beta 7.26 is seemingly only to focus on the random seeding issue [to prevent 'some duplication', at least not heard anything different being in view. 2 of 3 batches have circulated [0000000 and 9999979, turning out to be 9999975], the wait on the 3rd special build batch, no one haven broken silence of it going around. :!

Most of my systems are running Ubuntu. All of them are running in service mode.
----------------------------------------There appears to be no commonality between WU and it appears to be quite random across systems. The machine in question is a 12 core HT server and only those four got stuck. After reboot the elapsed time reset to the CPU time and they're happily crunching along. This has been an ongoing issue since Beta 7.24, I did not encounter it previous to that. In the past I would just abort the units that got stuck and the wingmen/repairs would continue without issue. Like I say, it's quite random. Less than 5% of the cores ever experience this problem when it occurs and it can be days between instances. My only hunch is that it has something to do with an unavailable internet connection. Distributed computing volunteer since September 27, 2000 |

Nope, I gave up on Ubuntu wifi years ago. This has happened on my windows systems as well. Just moved into a new house and the DSL has been spotty. It seems to be working better now though.

Just recognized, I also have one work unit with status 100% but running without checkpointing for 134 hours now.
System: Intel i5-3320M, Win7 32bit, Boinc 7.0.28 <stderr.txt> Commandline = projects/www.worldcommunitygrid.org/wcgrid_mcm1_7.24_windows_intelx86 -SettingsFile MCM1_0000033_4508.txt -DatabaseFile dataset-17_72_SDG_v1.txt Initializing wcg_learn_limit = 500000 Running Until today also no result from my wingman. https://secure.worldcommunitygrid.org/ms/devi...s.do?workunitId=885072792 Deadline will be reached in two days. Do you expect any reasonable result or shall I abort it? Regards, Rutor |

New work is downloading, but none of it can start because some files are failing to download ...
"Temporarily failed download of wcgrid_mcm1_7.26_i686-pc-linux-gnu: http error" |

Kremmen,
The download servers are serving lots of large files right now and clients are having to backoff to help allow files to be served as quickly as possible. Thanks, -Uplinger |
