目前应该是 deepbit 欢乐时间. 现在 deepbit 还没有出数据, 立此日志为据.

验证: 21:53, 21:55, 22:07 三块是 deepbit 的. 22:01 的属于 bitcoins.lc

俺有兴趣，昨天收到你的邮件还没捐助呐，估计明后天才能捐助。你给的代码还不会折腾，不是程序员，之前几台矿机都是按照指南搞的，囧

目前情况: 服务端算法不良导致错过了 deepbit 的一小波高潮. 已修正.

如果有相当的计算能力，比如几百m甚至上g的话，这个跳跃应该还是相当可观的。之前我也想到了，但不知道咋算法，个人菜了点，呵呵。推荐有计算能力的朋友试试，我自己就算了，只有一块破显卡～～

cont.
每有 long polling 送来新 block 的时候, 就会自动查询新的 best pool. 此外每 300s 查询一次, 以减少 shares 浪费.

这个提高的原理是什么？感觉像是提高工作队列的效率？

fcicq

2011-07-06 10:12:56 +08:00

那只是提升之一. 独家的 pool 推荐算法, 客户端支持 hopping 缺一不可. 重复提交(从其他分支移植来)减少网络损失, failback 功能(已进入官方版本, 但 hopping 与其有冲突, 做了大量的修改以保留该功能) 让人安心不怕 DDOS...

虽然话说如此, 服务端暂时稳定性还不够, 被 deepbit 和 btcguild 搞的挺难受的...

忘了说那个 queue 的功能了. 那个在另一篇里有说明, 防止 miner is idle, 保证长期满速工作.

实测 14h, 比理论收入高 23.9%, 未计 deepbit PPS, 未计 bitcoins.lc 上未确认的 shares (预计 0.03+)

@fcicq 这个有搞头，安装起来麻烦不，有温度监控自动重启等功能么？

fcicq

2011-07-11 22:34:45 +08:00

@milazi 只有 miner 的功能(能定时/在 block 变化时切换到当前最优的 pool), 其他监控什么的都不管. 今天的新功能是无缝切换, 已经可以做到不停 GPU 了(如果要切换的 pool 挂掉的话就不会切换了), 如果切换的话至多损失 1/frames 秒的计算能力. 之前需要重试连接 4 次以触发 failback, 约需 15s.

2011-07-11 22:46:49 +08:00

今天 0:00 - 21:00 数据, 实测比预期(1055 * mhash / difficulty * 21/24)高 +21%. 其中包括一台机器不到 30min 的停机时间.

fcicq

2011-07-11 22:51:54 +08:00

啊. 应该是 20h. 比预期高 27%.
