mlemanczyk 07efd5d2a1 Accelerator locks removed 2025-11-23 14:59:29 +01:00
mlemanczyk 5cac51479e GPU memory allocations protected with lock to prevent shared memory access issues. GPU usage limited for the best performance. 2025-11-19 16:49:01 +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.

mlemanczyk f4e365194d GpuContextPool removed, because we share context and accelerator between threads, using streams to separate. 2025-11-07 12:52:20 +01:00
mlemanczyk 7c035239b4 Cleanup. Classes & structs extracted to their own files. 2025-11-07 10:34:31 +01:00
mlemanczyk 119690086a ConcurrentDictionary removed. Kernel made dependent on the shared GPU context. 2025-11-07 10:16:33 +01:00
mlemanczyk de2a78b27b Streams added to all kernels and GPU operations to separate threads from each other. 2025-11-06 18:53:55 +01:00
mlemanczyk 64d615c402 Various optimizations to separate non-static data between threads and resolve read/write access issue. 2025-11-04 20:45:56 +01:00
