There must be a few WUs getting lost out there. You know how each
unit is sent out with a _0, _1 and a _2 suffix so that each unit is
calculated three times and cross-checked? Recently I've noticed a
few _3's and _4's and today I got a _5. Obviously a few results are
being lost or not returned. My understanding is that, if all three
'units' haven't been returned by the expiry date they send out
however many other copies are needed to get the three results. A _5
must mean that all of the original three units were lost.
Just thought I'd mention it. Anyone seen one higher than _5? Just
curious.
It could also mean that the first returns weren't within
"computational" sameness. Meaning that the first return may have asked
for 35 credits while the second was asking for 68 credits and the
third was asking for 2 credits. Something is wrong and the units
would be sent out again and again until 3 returns are within alowable
limits. Those limits are set by the Scientists and can of course be
changed.
True, true. I was thinking in these cases it may have been due to loses
resulting from the server outages and maybe people uninstalling BOINC and
the WUs dissapearing.
Could be a large part of it.
Oh, I just looked and on two of my machines I have an _8 but I just
manually made one machine connect and got all _0s and _1's.
