Change Log
----------
v3.18.1
More speed for scrypt:
- additional scryptn2 optimizations for all CPU architectures,
- AVX2 is now used by default on CPUS with SHA but not AVX512,
- scrypt:1024 performance lost in v3.18.0 is restored,
- AVX512 & AVX2 improvements to scrypt:1024.
Big speedup for SwiFFTx AVX2 & SSE4.1: x22i +55%, x25x +22%.
Issue #337: fixed a problem that could display negative stats values in the
first summary report if the report was forced prematurely due to a stratum
diff change. The stats will still be invalid but should display zeros.
v3.18.0
Complete rewrite of Scrypt code, optimized for large N factor (scryptn2):
- AVX512 & SHA support for SHA256, AVX512 has priority,
- AVX512 & SHA support for sha256, AVX512 has priority,
- up to 50% increase in hashrate,
- memory requirements reduced 30-60% depending on CPU architecture,
- memory usage displayed at startup,
