首先是为了更好发挥动态PGO的性能，JIT编译器中为分层编译引入了更多的编译层数。需要引入更多编译层数的原因主要有两点。第一，插入各种采样的指令和代码是需要代价的，考虑到第0层编译的主要目标是为了降低编译的时间，提高应用的启动速度，在第0层编译过程中就不能插入太多的采样指令。因此编译器首先增加了一个新的编译层——采样第0层来解决这个问题。大部分的方法将在第一次运行时编译到缺少优化、缺少采样指令的第0层，在运行时发现该方法被调用了多次之后，JIT编译器将这个方法重新编译到采样第0层，再经过一系列的调用之后，JIT编译器将利用采样得到的信息对该方法重新进行编译并优化。第二，在原始编译器模型中使用即时运行（R2R）方法编译的代码不能参加到动态PGO中，尤其是考虑到几乎所有应用程序都会调用的核心库代码是采用R2R的方式进行运行的，如果这部分的代码不能参加动态PGO将不能够完全发挥动态PGO的效果，虽然核心库在提前编译的过程中会使用静态PGO进行一部分的优化。因此JIT编译器为R2R编译好的代码增加了一个新的编译器，在运行时发现这部分代码被调用多次之后将会被JIT编译器编译到含有优化和采样代码的采样第1层，随着调用次数的增加这部分的代码将可以利用采样得到的信息进行优化。下面这张图展现了不同编译方法在运行过程中可能达到的编译层级。

异构编程/运行时系统的任务映射机制主要有两种：一类是直接映射，即独立完成并行任务向异构平台映射的工作，另一种是间接映射，即需要借助其他异构编译和运行时系统协助来完成部分任务映射工作。直接映射系统一般在运行时系统中实现，而间接映射通过源到源变换和是运行时分析相结合的方式实现。

oneAPI是Intel公司提出的一套异构并行编程框架，该框架致力于达成如下几个目标：（1）定义一个跨架构、跨制造商的统一开放软件平台；（2）允许同一套代码可以在不同硬件制造商和加速技术的硬件上运行；（3）提供一套覆盖多个编程领域的库API。为了实现这些目标，oneAPI同上文中已经提到过的开放编程标准SYCL紧密合作，oneAPI也提供了一个SYCL的编译器和运行时；同时oneAPI也提供了一系列API库，包括`oneDPL`、`oneDNN`、`oneTBB`和`oneMKL`等。

我对于oneAPI的理解就是Intel用来对标NVIDIA的CUDA的一套高性能编程工具箱。首先为了和NVIDIA完全闭源的CUDA形成鲜明的对比，Intel选择了OpenCL合作同时开发SYCL，当时也有可能是Intel知道自己的显卡技不如人，如果不兼容市面上其他的部件是没有出路的，同时为了和CUDA丰富的生态竞争，Intel再开发并开源了一系列的`oneXXX`。 diff --git

最简单的方法是在浏览器中输入[这个网址](https://vscode.dev)，就可以在浏览器中打开一个VSCode Online，这个版本的VSCode可以支持打开本地的文件，并且进行编辑。不过这个编辑器并不支持大部分的插件，而且并不支持程序的编译与运行，并不是一个可以开箱即用的编辑器。那么还有什么办法可以让我们拥有一个联网即可得的个人定制化开发环境呢？ @@ -53,9 +54,9 @@
