I thought for Rosetta all the machines should produce different results anyway because of the randomness seeded into the calculation? ID: 70327 · Rating: 0 · rate: / Reply Quote

I thought for Rosetta all the machines should produce different results anyway because of the randomness seeded into the calculation? Normally this is true. In this case though the outcome of the task was something other than success (could be a failure: could be the machine not completing the task before the deadline). BOINC will automatically send such tasks out again to another machine. Note the incrementing final digit at the end of the task name: that indicates how many times the task has been resent.

I thought for Rosetta all the machines should produce different results anyway because of the randomness seeded into the calculation? A validate error occurs when the validator (the process on the server that checks to see if the result sent back is acceptable or not) has some sort of error in the validation process itself. If the validator is programmed well enough, that means that this error was caused by the validator itself having an error that is not caused at all by the result. Sometimes, the programmer of a validator incorrectly makes the validator declare a validate error when in reality the result should be marked invalid. ID: 70344 · Rating: 0 · rate: / Reply Quote

Though the credit dose not appear on a Tasks For User page. Or on the Workunit Details page. Only on the Task ID page do we get to find out that it was valid after all :¬) Like this is one of mine https://boinc.bakerlab.org/rosetta/workunit.php?wuid=385050333 All three of you did get credit for the work done.
