AQUA's complex work units have meant extremely long running times, especially on slower systems. This has been a problem for volunteers as well as the project managers. We have been working intensely on improving the efficiency of our applications. One major achievement has been very high CPU utilization on multi-core computers. But this solution will not be of any use on single core CPUs. We appreciate all of our volunteers and their help, but sincerely believe that slower machines can be of much more benefit in BOINC projects with shorter running work units. For this reason AQUA will no longer send work units to single core CPUs. Hyper-threading CPUs are supported, though. Should we again release a CUDA version of our application, single core CPUs will be supported if the system has a CUDA card. Vectorization of our code also implies that SSE2 support is a requirement for running AQUA's applications.
因为项目的大任务运行时间长,如果用户的计算能力相对较差的话,对用户和我们都是一个麻烦。
我们非常感觉所有用户的贡献,但那些相对较慢的计算机可能更适合处理那些任务较小的项目。
因此我们将停止将任务分发到单核的处理器(不包括超线程的),除非这些机器上还配备了CUDA显示卡。

In order to better utilize CPU and GPU cycles, we've optimized our code considerably. Though all platforms and OS versions are affected, the 64-bit Windows application has specially gained in performance. Hopefully this will reduce the running times needed to process heavy work units.
为了更有效地利用计算资源,我们已经对代码进行了相当程度的优化。虽然所有平台应该都有提升,但64位windows平台的提升是最大的。希望这能够减少完成大任务所需要的时间。

AQUA now has a screensaver for its Windows application! The nice graphics display is complemented by useful information, showing the user the multiple chains involved in Parallel Tempering Monte Carlo, and the amount of progress the application is making.
Windows平台的计算程序有屏保啦! |
