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 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
mlemanczyk 13498dc460 Most device buffers integrated into PrimeOrderCalculatorAccelerator. PrimeOrderCalculator switched to partial factoring on GPU. 2025-11-26 03:16:39 +01:00
mlemanczyk b9ca95bf8c PrimeOrderCalculatorAccelerator.Rent is now created outside of the loops and re-used for all calculations. 2025-11-24 22:51:53 +01:00
mlemanczyk 57a50e2a37 Pow2Mod kernel specific methods moved to Pow2MontgomeryKernels. 2025-11-24 18:04:07 +01:00
mlemanczyk 070e2a14fd MontgomeryDivisorData converted to a pooled class to limit GC pressure. MontgomeryDivisorDataGpu added for GPU operations. PrimeOrderCalculator kernels precompiled during warmup. 2025-11-24 15:14:31 +01:00
mlemanczyk 801b1be3e3 Cleanup 2025-11-18 04:22:39 +01:00
mlemanczyk 342eff2726 GpuKernelPool.GetOrAddKernels removed in --mersenne=bydivisor mode. PartialFactorResult.WithAdditionalPrime will now modify the current instance instead of creating new copy for better performance. SmallPrimeFactorViews renamed to SmallPrimeFactorGpuTables for consistency with other static tables. 2025-11-17 23:33:59 +01:00
mlemanczyk c413ee1162 Revert "Stream handling simplified to avoid dictionary lookups in favor of array lookups with known indexes." 
This reverts commit a84445ef2a.
