Just manually updated the wu's from overnight crunching and host info is now remaining intact here after a credit update.

Yep. Host location was gone. Reset to correct venue (home, school, work) and all came good.


This corrected my problem also.

<blockquote>We are waiting to get another server which we will use for backup and testing purposes. We will install BOINC5 and MySQL4 on that and start alpha-testing. But I don't know when this will happen.

Anyway, we are not in hurry with BOINC5. We let other projects experiment with it for a while and see how they are doing:)

LHC is now the only one of five projects I run which is not v5 compatible and this version will become the standard soon I think. Any updates on this?

Yes lots of interesting reading there. This caught my eye. No need for optimised apps for LHC I think.

"The LHC simulation that was chosen to be the basis for LHC@home was SixTrack. SixTrack
has been developed over the last 20 years by Frank Schmidt, and is used by CERN and other
synchrotrons3 around the world to do beam studies. Like much of CERN's older software it
is written in Fortran. On the initiative of Eric McIntosh it is also used as part of the SPEC4
floating point benchmark. So CERN, when buying new computers, never have to estimate
how well a new processor will run SixTrack, but can look it up directly. Another added benefit
is that manufacturers will optimize their hardware and compilers to get the best benchmark
score, so modern CPUs and compilers are directly optimized for SixTrack performance."

Linux is always different than windows ;) My Xp machine just downloaded 4.67 with 18 wu's so all is still well.

Posted 22 Feb 2005 by Digitalis
Post:
AFAIK this is how it goes. In order to merge machines thet must have the same cpu and operating system. BOINC has changed the description of Intel cpus from "Intel(R)Pentium....." to "Genuine Intel(R) Pentium...." hence they are treated as separate machines. Your total credits will still be ok.
