You got the same amount of credits as a PIV 3GHz and it seems yours gave some kind of error ???

Looks like it is the known problem of the validator granting credit to the first result when it is returned past the deadline.

1. First WU is sent out.
2. Deadline passes (was due back by 2/24)
3. System hands the WU out again to another computer.
4. First computer returns WU. Since it is past the deadline it should be marked as invalid but it is not and credit is granted.
5. Second WU is returned but since the first one has credit, the second one gets the same amount of credit.

I had the same kind of thing happen this evening. https://boinc.bakerlab.org/rosetta/workunit.php?wuid=6346111

Perhaps this may be related to the new variable work unit length?

For instance, if host "a" misses a deadline aor errors out and the wu is resent to hosts "b" and "c" what happens if host "b" has a work unit length of 2 hours and returns a result getting x number of credits. Then host "c", which has a work unit length of 8 hours returns a result also. Why should "c" receive the same credit as "b"?

Is this in fact the way the system works?

I updated the validator today to fix this issue. I also granted the appropriate claimed credit for results whose granted credit was less than the claimed credit. The difference was added to the user, host, and team totals.
