is it new with version 5.24 that you don't get any credit for WU that stop with a computation error, I had a few these last days.

Credit issuance is up the projects. Rosetta always grants credit for work performed. This is done in a daily job. Your computation errors are given credit. But you have to look at the WU details to see it. Like this one. They don't show in the full WU list.

Crunch more Rosetta!

And if you're getting numerous errors, please consider connecting to the RALPH project with a 10% cpu time share - so the errors can be tracked down and killed off.

i wondered because there is 1 or 2 workunits from June 21st still without credit, so I guess the servers must be busy.
Yes, I registered at ralph.
Also I never had much problems with errors using rosetta 5.22

Looking at your WUs for June 21st, from all three machines, I find this one, and this one. As you can see by displaying the specific WU details, both were granted credit. As I mentioned before, they WU LIST does not show the credit granted for the errored WUs.

Hmm... don't know if it'll ever be a real problem, but this gives a potential loophole for getting excess credits which will still be open once the RosettaBench system is active. Return a deliberate -161 error with 3 hours of CPU time reported ... !

I saw a machine a few weeks ago with 'high' benchmarks, 100% unsuccessful work units, very high RAC and credit score. Did wonder at the time how it was getting credit if the WUs were failing. No doubt an innocent explanation exists. Hope this never happens deliberately.

In those cases I agree, if a computer only produces errors, why should it get credit... Because then it's not even helping the project.

I certainly agree, this approach to granting credit opens that door for abuse. I did just want to point out that often times a WU will end in a failure, but successfully crunch several models. So they are helping the project both by completing models, and by debugging.
