I pushed search limits for 1021 a bit further into large primes territory, so memory requirements are higher now (all primes up to 1011 are checked). CPU version requires 2.85 GB of system memory. GPU version fits in 1 GB on GPU, but requires 8 GB of system memory after refactoring.


I ran a few of the 10^21 beta tasks (CPU) on a 4GB Win 7 laptop. The tasks ran happily, using about 2.83 GB on 4 cores..
