Post:
Hello,

I also noticed a credit difference for me. (I only do sixtrack)
in the statistics by application, I see 175,065,281 for sixtrack and 6,008 for theory while in the total statistics I see 194,195,947
In 'my account' page, the total credit is 194,308,844
I do not know where this difference comes from but I think it appeared when merging the sub projects of lhc@home.

Hello, it's been 10 years today that I started to participate in the project lhc@home.

I hope that these ten years of contribution and all these kwh have been useful to CERN in making the LHC a powerful tool for advancing scientific knowledge in quantum physics.
I also hope that your research will make the time travel possible soon :-)

Keep going on!

what can i do to correct the problem on other hosts? reset project?

I can't test new tasks now because all my hosts goes offline this night for holidays but i come back after and check all new tasks in error.
Thank you very much for solving this mysterious problem!

With lhc@home consolidation, did you consider to balancing credit between applications?
Actually, there is so much differences between projects credit calculation, and it's not fair to merge ranking in these conditions.

Hi!

There is a lot of WU to send now, and all my hosts receive a lot and get cache full :-)
But one of them not receive wu.It's a virtual machine under linux amd64 and xeon processor.
My others ohsts are physicals machines with intel i5 and linux adm64.

There is a problem with the intel Xeon and linux amd64? or with virtual machine?
Why only this host don't receive wu and can't get cache full?
