Not sure what has happened here as both machines pulled the same WU but hours apart...

Any idea's as to why this has happened? I do know that if you download units at the same time you can get a duplicate but the downloads were a good 14 hours apart.

2nd question - will I get credit for both units?

Posted: **Tue Jul 23, 2013 4:28 pm**

Work units are assigned to several machines across the spectrum. Your two machines just happened to catch the same work unit. You will receive credit for both of them when finished.
Nothing unusual, just the luck of the draw.

Its very unusual, hence the post. WU are usually only resent out if a machine has sent a partial WU in, the WU is corrupted or has missed a deadline - Unless something has changed recently?

Posted: **Tue Jul 23, 2013 4:44 pm**

It has not changed, and is a rare occurrance. WUs are sent only once unless a problem comes up. Then the server generates a copy. If there are multiple failures, like with a bad WU, multiple copies can be sent.

And yes, you will get points for both, if you wanted to let the 2nd copy keep running.

A mod will be along shortly to check on the WU and mark it as bad if needed.

From the format of the log files, both machines are running the V6 client. As long as you did not clone the installation so both machines have the same ID's assigned, this happens occasionally and is okay. If you did clone the F@H installation, then you need to completely uninstall it from one of the machines, including data files, and reinstall. On connecting for the first time the client will be given an unique ID. Without unique ID's a WU request from the second system a short time after a request from the first can result in getting a duplicate download, and on return the duplicate upload is discarded if you have a successful return from the first. If the returns are from two different machine ID's they are not considered duplicates.

Normally a WU is sent out to only one machine. If it does not come back within the preferred deadline, then the WU will be sent out again. Usually that is to two other machines. This is repeated until there is a successful return or enough failures occur that the WU is suspended from assignment as a possibly bad WU. In this case the WU has no reports in the database, will mark this for rechecking later.

Look carefully at the first page of the logs. Do they show the same UserID/MachineID? (Not to be confused with UserName, which should be the same.)

Posted: **Tue Jul 23, 2013 5:38 pm**

No cloning, both machines were done from a fresh install months apart and the user ID's are different. - and having chewed through several kilowatts of leccy i'm not about to dump a WU.

You will only every get credit for one WU (If they are the same). You might as well get rid of a 2nd copy and start a new WU.

This is not actually true. As long as the machines have unique ID's, two copies of a WU that happened to be assigned to the same user will get credit. Where persons have not gotten credit for working on two of the same WU has been when they cloned a F@H install to another machine after it had connected to Stanford and the folding servers at least once and been assigned an User ID.

To follow up, both have finished and been turned in:

Hi Nathan_P (team 33),
Your WU (P8105 R0 C12 G84) was added to the stats database on 2013-07-23 22:05:03 for 253933 points of credit.

Hi Nathan_P (team 33),
Your WU (P8105 R0 C12 G84) was added to the stats database on 2013-07-24 05:05:07 for 285356 points of credit.

Posted: **Thu Jul 25, 2013 7:27 am**

Thanks, things are now back to normal and both machines have pulled different WU.
