(moderation:
Hello ladies and gentlemen,
I am running BOINC Einstein@Home and have completed two WU's which are still on my computer, unsent. The BOINC manager shows me he downloaded two more WU's and the unsent ones are still there on my computer, struck at 100%
They are shown in green on my account, like if they were never reported. Their ID's are 35224119 and 34955408.
My network works (sucessfuly pinged Einstein@Home) and anyway, the computer i wrote this message on is the one running BOINC. Also, even if no WU were uploaded, two brand new ones were downloaded. BUT, the download date seems a little bit old: my personnal page says i got them yesterday and am nearly sure i downloaded them this afternoon 03/11/2007. I said NEARLY sure.
I cant' do anything with the "transfert" tab like forcing an upload or something.I restarted my computer without apparent effect.
The server is up and running, i was beginning to think there were two servers, one which sends and one which recieves but the christmas tree is all green.
My system is an GNU/Linux ubuntu 6.10 with the 2.6.17-12-generic kernel
Here i copy/paste my message tab in the BOINC manager:

Post scriptum:
WOW ! You fixed it even before i posted it ! That's scientific community symbiosis ! Thank you thank you very much folks, i've never seen a so efficient community.
P.P.S Uh, more seriously, now that it's fixed, I would appreciate if someone tells me the ins and outs of the scheduler since it appears to be the culprit there...
EDIT: Erm.. some spelling grooming.

Welcome to E@H!
This is confusing many users: Whenever BOINC completes a result, it will NOT automatically upload it immediately. Instead, it will try to combine many completed results in a single transaction. Of course if no second completed result appears for some time, eventually also a single completed result will be uploaded and reported. It's all about minimizing the stress on the server side part of a BOINC network.
The BOINC gurus here might want to explain this in more detail, but I guess that's the basic story.
Happy crunching!

Thank you for the explanation, Bikeman. :-)
I forgot to mention i had read the FAQ and found no matching entry. Maybe a "why my completed WU's aren't sent to the server ?" could be of some use.
Have fun.

Strictly speaking, there are

Strictly speaking, there are two completely separate processes.
1) Uploading
This is when the scientific data gets transferred to the Einstein servers. If you are connected to the internet, and networking is allowed, it does happen immediately after a workunit finishes crunching: you can see the file progress (briefly) on the transfers tab, and there will be messages in the message tab:
02/11/2007 14:31:20|Einstein@Home|[file_xfer] Started upload of file h1_0414.90_S5R2__130_S5R3a_0_0
02/11/2007 14:31:29|Einstein@Home|[file_xfer] Finished upload of file h1_0414.90_S5R2__130_S5R3a_0_0
02/11/2007 14:31:29|Einstein@Home|[file_xfer] Throughput 16684 bytes/sec
However, the task will still show at 100% in the tasks tab, and there will be no indication on this web site that anything has happened.
2) Reporting
This is when all the administrative tidying-up happens: letting Einstein know that there is a new scientific result that needs checking, filling in all the statistics about how long the work took etc. Depending on your version of BOINC, this can happen up to 24 hours after the scientific data upload. Only once its been done do you see any acknowledgement of your work on the website. This is also the point at which the WU disappears from your tasks tab, and you see this in the message tab:
02/11/2007 14:45:59|Einstein@Home|Sending scheduler request: To report completed tasks
02/11/2007 14:45:59|Einstein@Home|Reporting 1 tasks
02/11/2007 14:46:04|Einstein@Home|Scheduler RPC succeeded [server version 601]
Hope that helps: feel free to copy it into a FAQ if you want.
The >Update Project< function
)
The >Update Project< function allows you to report finished tasks manually to the server, but there is no need to use it unless you want to report them immedately because you may go to vacation for the next weeks or so.
