Windows64 and Linux64 users can now run native 64-bit AQUA applications on their machines! We thus want to thank our volunteers with 64-bit operating systems and also contribute to the spread of 64-bit computing.

项目开始提供64位版本的计算程序!

The AQUA@home project needs enourmous computing resources, so we have been working on using NVidia GPUs to reduce the running time of our application. We are happy to announce that version 3.00 of AQUA's application, supporting NVidia CUDA cards under Microsoft Windows, is now available for testing. Linux and Mac versions will follow in the next few weeks. We hope to gradually increase the performance of this version.

因为项目需要非常多的计算资源,所以我们一直在开发能利用到NVidia显卡的计算程序。现在3.0版本的计算程序已经发布出来并开始公开测试,支持在windows平台上使用nv的显卡进行计算。linux/mac平台的用户还要再等几个星期。

// 话说利用gpu的项目已经越来越多啦~

Up to now AQUA used to employ a single core to process its data. Starting with version 2.18, AQUA's appication uses multi-threading to use multiple cores and speed up its computation. 32-bit and 64-bit Windows, Linux, and Mac platforms are supported. AQUA's application uses OpenMP to create and manage its threads. So now AQUA uses either CUDA or OpenMP (but not both at the same time) to decrease its execution time.

从2.18版本开始,本项目的计算程序将通过多线程同时使用多个处理器内核,以加速任务包的计算过程。

支持32位/64位的win、linux、mac。

Like using CUDA cards, multi-threading is a way for us to shorten the run time of our work units. Multi-threaded applications are new to BOINC, so you will see behaviour such as one application using all the cores in the computer. Please allow such work units to continue running. BOINC makes sure that all projects you are subscribed to will receive a fair share of your computing resources. We need your help in getting this research done. Thank you for your support!

和cuda一样,使用多线程的目的也是为了减少任务包的完成时间。

计算程序多线程化对boinc来说还是比较新的特性,因此你会看到计算机中所有处理器内核和被一个计算程序所占用的情况。但boinc会确保所有你参加的项目都能得到相同的计算资源,所以请不要试图中止掉这样的任务包:)

我想問aqua現在還有沒有cpu包?
每次更新都說我沒有支持cuda的n卡,所以不派包
但不是有cpu版的嗎?
我在用戶設定裡禁了cuda版後
它還是這樣說啊~

我也是这问题,不过原因是显存不够。

任务一点都不多,已断粮将近一周!

话说这个项目的 CPU 包确实是很有分量哦,可以慢慢算 3 个月!

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!

现在AQUA变得巨慢,10小时才算了15%。

我说,AUQA从此没落了?
还有三千多个WU屯着。

The new AQUA application (version 4) is now ready. The algorithm has been improved to better measure the size and place of the minimum gap in the evolution of a quantum system. There is also better load-balancing for multi-core CPUs. AQUA will be performing full-scale runs starting today.

新的AQUA计算程序(版本4)已经准备好了,主要是在算法上有进一步的改进,还有就是多核处理器上更好的负荷均衡,将在今天正式开始运行。
