I examined this, and found out that there is actually 197
assignments checked out to this individual (188 to the same
machine ID (7 dbl-chks, 5 factoring, 176 L-L tests)). By
my estimates, this single machine ID has >5 yrs worth of work
for even the faster state-of-the-art PC. While they have
various run times, they all have 16 days to go and 16 days
until expiration... They all were also updated on the same
date and time (10-Feb-00 17:55). None appear to have had
any work performed on them at all!!
While I normally might think this might be a person switching
over to use PrimeNet from previously not using it, and possibly
using a large cluster (using the same ID for the entire cluster),
there are a few indications this isn't the case. First, their
ranking on PrimeNet is 8112 and 2323 for primality testing and
factoring respectively, and their P-90 CPU hrs/day at 13.79.
Second, their ranking on George's list is 6800 (with only one
additional exponent tested above PrimeNet's count). Finally,
they have 6 other machines that actually appear to be performing
some kind of work.
In any case, these exponents will expire in 16 days. As a
result, I'm not concerned about it. Within 3 weeks
they'll be re-circulated among other users. The only thing
that would cause concern, is if the user intentionally updates
these exponents in the next two weeks...
