mlemanczyk 7a242b3bfa PrimeOrderCalculator.PartialFactorCpu simplified to work only with spans and throw exception if the number of factors is exceeded. PrimeOrderMode removed in favor of bool flag. 2025-12-10 12:47:25 +01:00
mlemanczyk 86f20ed083 Support for q > 2^64 added in --mersenne=bydivisor mode 2025-12-05 23:33:21 +01:00

mlemanczyk 86192a71b0 Divisor checking optimized to only flag if divisor was found or not without returning complete array of hits. We'll now also track residues for 13, 17 & 19 as the most frequent ones. 2025-12-03 00:57:25 +01:00
mlemanczyk f43c67c86f Tasks will now save calculations progress and resume calculation upon restart. 2025-12-02 00:42:38 +01:00
mlemanczyk 941733905b Hybrid device mode implemented as the current --mersenne=bydivisor CPU execution path. CPU path is now limited to CPU calculations, only. 2025-12-01 03:45:39 +01:00
