We've added two mechanisms that give better estimates of result completion time (and thus better scheduling and fewer missed deadlines): 1) we track the 'CPU efficiency': the average fraction of CPU time that BOINC apps receive while they're running (this can be less than one on systems that run compute-intensive tasks other than BOINC); 2) we dynamically maintain a per-project upper bound on the ratio of actual CPU time to predicted CPU time.

我们增加了二个机制,以更好地估计任务完成时间(能更好地安排任务,更不容易过期): 1)我们跟踪'CPU 效率':当BOINC客户端运行时会统计平均Cpu-time(当前台程序计算量大时,统计值可能为零); 2)我们动态地更新每一个项目的实际Cpu-time与预测的Cpu-time的差别。

We've improved and simplified the CPU scheduling and work-fetch policies, using a detailed simulation of BOINC's weighted round-robin scheduling. When the simulator predicts that a deadline will be missed, the client switches to earliest-deadline-first scheduling. When the simulator predicts that fetching additional work will cause a deadline to be missed, it suspends work fetch.

我们改进了和简化了CPU预测和任务分配政策,使用BOINC细节循环模拟调度。当模拟器预测到有要到期任务时,客户端会优先计算能及时完成的任务。当模拟器预测到下载新的任务将导致一个已有任务过期,它会取消任务下载。

Account management system are web sites that let participants sign up for multiple projects with just a few clicks (and no account keys). The BOINC manager (development version) now lets you select, change, or get updated account info from an account manager.

帐户管理系统是让参加者通过简单的点击参加多个项目的网站(无需项目帐户密匙)。BOINC的客户端软件(开发版)现在可以让您通过帐户管理选择,改变,或取得最新的帐户信息。

BOINC now works in Windows 'service' mode on computers with dialup connections and the 'confirm before connect' preference set. The connection confirmation and setup process has been moved to the BOINC manager, which (unlike a service) is able to do GUI activities.

现在运行于windows'服务'模式下的使用拨号连接的BOINC,加入'连网前确认'选项。连接确认和设置功能被移至BOINC管理程序-(不同于服务)能进行GUI交互操作。
