This might be subject to change, but some preliminary info to end speculations here:
大概说一下,可能还会有变化。
Most likely S5R4 will start with Applications very similar to the last Beta Apps, i.e. SSE2 App for MacOS Intel, switching x87/SSE App for Windows, switching G3/AltiVec App for MacOS PPC (which will remain the slowest one in comparison), and an App that switches SSE2/SSE/x87 Apps for Linux.
S5R4的计算程序应该会和之前阶段的beta测试程序(优化程序)相似,比如MacOS Intel平台的SSE2版、Windows平台的X87/SSE版,MacOS PPC平台的G3/AltiVec版(可能会是相对比较慢的一个),还有Linux平台的SSE2/SSE/x87版。
The next improvements targeted for the Apps are getting the Windows App compiled with MinGW, so gcc-specific improvements could be ported to Windows (SSE2 optimizations), and, more general, get the "weighted" Hough code up to the speed of the currently used "unweighted". As the main improvement there is the prefetching, I'd suspect systems with a faster memory interface (AMD) to be a little faster in that part at the beginning.
Windows平台的计算程序会改用MinGW来编译,这样一些gcc相关的改进将能够移植至Windows平台(SSE2优化)。由于预读取方面的改进,刚开始时可能拥有更快的内存接口的AMD系统会表现更好些。
However before that we have to get S5R4 running at all, and an almost equally high priority is a major server code upgrade. I doubt that any major work on the App code will be done before that.
在所有这些之前,首先还得把S5R4给跑起来,服务端的代码升级也要优先处理。这些工作完成后才会去处理计算程序代码。
