在大部分机器上,unsigned int的最大值要比int的最大值大两倍,比如说再也给16位的机器上,unsigned int的最大值为65535,int的最大值为32767。 尽管int类型的大小依赖于C编译器的实现,但是在给定的平台上int对象的大小和unsigned int对象的大小是一样的。因此,使用unsigned int修饰第三个参数的代价与int是

Llama.cpp是用C/C++实现的用于部署LLM推理模型的开源框架,支持多种后端。主要是使用了作者开发的ggml这个库。关于ggml, 请参考之前的文章深入理解GGML。 Llama.cpp项目地址在https://github.com/ggerganov/llama.cpp,主要是支持llama系列的LLM。 这里引用项目中README中一段描述: ...
