Ahh, you learn something new every day!
Sounds like he was a colleague of Murphy. :-)
There’s another rule that says the first 90% of a job takes up 90% of the time allocated, and then the last 10% takes up another 90%.
But my favourite such principle is Hofstafdter’s Law:
“It always takes longer than you expect, even when you take into account Hofstadter’s Law.�
(If you’ve read anything by Douglas Hofstadter you’ll know he enjoys recursion of all kinds.)
Just one more example of a rule of physics that we have not discovered yet.

This thread wouldn't be here if some information about the server status and the reasons why the "server is down"-messages keep coming up, was available on the Einstein homepage.
This is a short status update. All of us have been quite busy, as you probably can imagine, trying to fix all kinds of problems, and we still are.
I hope to have time to post some more info here as soon as it becomes available.

Hi there at EAH,
I know now that You all do YOu best to fix and solve the current situation, but to NOT disapointing the crunchers, it would be good that the news are regular updated. The last Info is from Jan. 7. :-( !
I'm getting that too. It just started about half an hour ago for me, when BOINC sent a request, and it got 12WU's (2-day cache) and reported 68. Way to go E@H!
to get needed time, take expected time, multiply it by 2 and switch over to next larger time unit
The problem with the original Westheimer's rule is that it's recursive...
No, seriously:
- We have started distributing Work of a run called S5RI this morning
- Lasting longer than the short Workunits of S5R1 this will lower the load on our database server, so things should go back to a more or less normal state from now (and already are...)
Actually the situaton went pretty bad because of a number of issues that happened at the very same time:
- hardware problems with the fileserver, causing delayed and thus accumulated reports
- S5R1 was coming to an end, with almost only short workunits left
- faster machines have been added after X-Mas :-)
- Bruce was (and in some sense still is) moving with his family from Milwaukee to Hannover, which means that everything at UWM was on David's shoulders
- currently due to the storm warnings in Germany facilities are shutting down and people are sent home, so we'll see how things go today
- We have started distributing Work of a run called S5RI this morning
- Lasting longer than the short Workunits of S5R1 this will lower the load on our database server, so things should go back to a more or less normal state from now
You might need to delete your app_info.xml-file. If this file is in your projects/einstein-directory it will prevent the new version to be downloaded.
After deletion, restart Boinc and the new WU's start coming :-)

I run only 2 projects on my 14 machines, with a .01 cache. I've NEVER run out of work and I don't babysit BOINC.
Just leave BOINC alone! It will send the units on its own!

They are named S5RI.

Storm warnings? That little bit of wind?
It is a little bit worse than last week's storm, isn't it? ;-)
