NBMiner v39.6

• optimize:ethash LHR mode significant improvement:

  • higher hashrate, more stable LHR unlocking for both -lhr-mode 1 and -lhr-mode 2
  • default LHR mode changes to -lhr-mode 1 for LHR GPUs
  • default values of LHR mode increased, -lhr-mode 1 -> 74, -lhr-mode 2 -> 71
  • added 3 new options for LHR auto-tuning control, at most cases you don't need to change:
    • -lhr-reduce-value: the amount to reduce -lhr value on a single -lhr tuning. defaults to 0.5.
    • -lhr-reduce-time: When LHR lock is detected, and the time since the last lock exceeds this value, the -lhr reduce will not perform. defaults to 15, which means 15 minutes.
    • -lhr-reduce-limit: the maximum number of times to reduce -lhr value, defaults to 6.
  • Typical hashrate: 3060Ti LHR on defaults options, 45.5 MH/s @ mem+1200 (win10)

• feature: ergo also adapts the 3 new LHR options.

• feature: add -cmd-output option to specify command line outpu to stdout or stderr, 1=stdout, 2=stderr, defaults to 2.

• feature: disable SNI extension for ssl connections by default, can be enabled with -enable-sni option

• delete: cuckatoo & cuckatoo32 support

• 优化: ethash LHR 模式显著优化

  • 算力更高，解锁更稳定的 -lhr-mode 1 （高算力模式）和 -lhr-mode 2（省电模式）
  • 针对LHR显卡，默认的模式改为 -lhr-mode 1
  • -lhr-mode 1中的-lhr默认值提升到74，-lhr-mode 2中的-lhr默认值提升到71
  • 新增三个用于控制LHR自动调参策略的选项，绝大多数情况下不需要修改：
    • -lhr-reduce-value：单次降低的-lhr值，默认为0.5
    • -lhr-reduce-time：距离上次被锁的时间，超过该时间则不进行-lhr降低，默认为15，即15分钟
    • -lhr-reduce-limit：最多降低-lhr值的次数，默认为6
  • 典型算力：3060ti LHR 默认LHR选项，45.5MH/s @ 显存+1200 (win10)

• 功能: ergo同样适配-lhr-reduce-value, -lhr-reduce-time, -lhr-reduce-limit三个选项

• 功能: 新增-cmd-output选项，可指定命令行输出到stdout或者stderr，1=stdout，2=stderr，默认为2

• 功能: 默认对ssl连接关闭SNI扩展，可通过-enable-sni开启

• 删除: cuckatoo 及cuckatoo32算法的支持
