Do you have see the new first user of rosetta?

https://boinc.bakerlab.org/rosetta/top_users.php

And its host:
https://boinc.bakerlab.org/rosetta/top_hosts.php
https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=105526

And this is the onli assigned WU:
https://boinc.bakerlab.org/rosetta/workunit.php?wuid=3530614

Looking at the benchmark, i think that joseph is cheating and with the quorum of 1 WU it's very easy to do. Please set the quorum to 2 WU and reset the total credit for that user and its host.

Bye,
GHz

This has already been discussed - the benchmarks on that machine are wrong. There is no evidence of cheating. This user's data will have to be adjusted after the project staff returns from the holidays.

Setting the quorum to 2 (or redundancy in general) has been discussed as well. Unless the _current_ plans (I believe) to replace the benchmarks with flops-counting fall through, there is little or no need to waste the computing resources on redundancy. The occasional problem like this one host can be dealt with manually.

I don't. Any cheat would surely set a value that was plausible, at least making it all numeric! I think it is another knock on effect of the buggy WU

PS - see also the user has a zillion credits thread in this forum

Do you thik that is a boinc error?

Ok :)

Flops-counting? Where I can find information about it?

until the problem is only one user there are no problems...;)

It's fallen to "page 2"... the Code Release and Redundancy thread. Contains _almost_ all the info we have right now. :-)

Who says it's occasional .. ?? I pulled this off one of the Hosts & it's by no means a rare instance as I can find many more like this ... 4,962.45 Credits for 11.68 hours of Processing Time. Is it any wonder the Rosetta Project is so Popular these days with this kind of Credit being asked for & the Project graciously giving it out.

There is discussion on ways to solve it - all are going to be manual processes until flops-counting can be put in.
