All my work units are being sent to me twice for validation (computer 682).

Apparently they have seen the same problem at nanoHUB.

By default, all BOINC workunits are executed twice for validation. This validation is executed in systems with the same architecture (OS and hardware combination).

I think the concept is well known to crunchers, the question arises when the same work unit is sent to the same machine twice. All that does is show that a machine performs consistently, if a gross overclock can produce incorrect results reliably,you pass it.
