Assignment Thresholds

The server will reassign exponents where the computer is 60 days past due in updating the server.
The server may reassign exponents that where the assignment is more than one year old.

Thresholds for "do what makes the most sense" work preference
Minimum Pentium 4 equivalent speed to get first-time LL tests 2000 MHz
Minimum Pentium 4 equivalent speed to get double-check tests 800 MHz
Maximum exponent assigned to CPUs with 128KB or less L2 cache 10,000,000
Maximum exponent assigned to CPUs with 256KB or less L2+L3 cache 20,000,000

Thresholds for first-time LL assignments
Force double-checks if CPU reliability less than 0.7
and CPU confidence level is greater than or equal to 2.0
Preferred exponents are below 38,000,000
Minimum Pentium 4 equivalent speed to get preferred exponent 2400 MHz
Required CPU reliability for preferred exponent 0.9
Required CPU confidence level for preferred exponent 2.0

Thresholds for double-check assignments
Force trial factoring if CPU reliability less than 0.5
