llama.cpp的rocWMMA flash attention进入主线了，现在可以用RDNA3/3.5/CDNA1+的tensor core加速flash attention实现更好性能的prefill和batch decode。较小模型的单用户吐字速度也有些许提升，应该不会再落后于Vulkan。不过目前主线版本暂时还需要手动打开编译选项。

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
