<blockquote>One of the problems with LHC@Home is that the work unit can end at almost any time. I once tried to see if I could make a histogram of the results so I could get better average times on the turn counts ... no such luck...

Now that I have a better "feel" for the work unit contents I may try again ... the only thing that may be a problem is that I am not sure that the "order number" is in the same character position ...</blockquote>

That's right, but all my wjun4C_v6s4hhpac WUs were finished between 6 and 12400 seconds, the w5_lhc_coll_IP15_trip_meas WUs are taking up to 22300 seconds.

What are these new workunits?
http://lhcathome.cern.ch/workunit.php?wuid=700416

It has a different name and takes much longer to compute.

Work is now available, it seems. I've got WUs downloading.

But only very few, they are all out now. :-)

Lot of new work now!

Don't forget, that the most hosts are slower and not running LHC 24/7.

First application now available, for the i686-pc-linux-gnu platform only. We are generating WUs, and of course we are noticing a lot of problems, as expected. Please report any problem, using the forums.

Orbit@Home Project Update: we are testing the scientific application, and adding the few more features needed in order to make it completely automatic. This first version of the scientific application will be able to determine the orbit of any asteroid, using only the astrometric observations. After completing our tests, we plan to generate work units and test it on orbit@home, hopefully within 2-3 weeks from now.
At the same time, since the BOINC team has recently introduced a number of new features, we will sync the orbit@home code to the latest BOINC version and fix all the related problems.

sulphur cycle experiment launched
Fri, 26 Aug 2005

From today, anyone downloading a new experiment from climateprediction.net will download an extended version of the experiment, which adds a fully interactive sulphur cycle to the model, to investigate the so-called 'global dimming' effect. People whose computer spec. (available memory or speed) is not sufficient for this experiment will continue to run the standard, 3 phase experiment. We expect this experiment to continue until early next year.

IIRC orbit@home will have some workunits with deadline below 24h, but these will be crunched in minutes, not hours.

But for most project 4 days will be too short, just a simple example:

An average PC needs 8 hours for one Einstein@home WU, if it is running only 3 hours every two days, you need 5 days until the WU is finished and returned. But most project are downloading two WU's at the same time, so you need atleast 10 days to finish your jobs.
