Einstein@Home running much slower than SETI@Home?

Your S@H WU was very probably crunching a WU with special signals resulting in a "Informational Message -9 result overflow". When this happens, the crunching of that WU is stopped prematurely.

I'm running a P4 HT . S@H CPU time is in the range of 4h.15min to 4h.30min. and E@H in the range of 11h.15min. to 11h.45min.

I agree that the execution time of E@H sounds about right. The execution time of S@H sounds too fast.

This can not be considered as a problem: it is a WU that maybe contains signals from earth source or other sources surrounding us.

If a WU with this kind of signals is crunched, that WU will generate a hughe number of signals that are detected.

Once the volume of the file that contains the found signals goes over a certain limit, the application will automatically stop crunching that WU and will generate the "Informational message -9 result_overflow" message.

I crunched some 1500 WU for S@H with Boinc and had some 70 WU's with this message.

WU stands for work unit

if you look at your uploaded WU you will see that several other people are working on it, however only you have reported the Result that's why your credit for it is still pending.
if you click on your result ID you will find more detailed information among other things the version of BOINC client that was working to produce that result

dont confuse WU and Result.
WU is what has to be worked on.
its result is what you report about your WU as a result of your work.
hence WU and its result have different IDs

Jeeze Thierry, did you have to tell, I was hoping Jim thought I was smart or something!
