执行引擎主要包括了解释器(Interpreter),即时编译器JIT(Just In Time Compiler)和垃圾收集器(Garbage Collection)。 目前大多数执行引擎采用解释器与即时编译器并存的架构,解释器和即时编译器相互协作,各自取长补短,选择最合适的方式来权衡编译本地代码的时间和直接解释执行代码的时间。 执行引擎结构 解释器(Interpreter) ...
首先,它是resources.limits.memory确定系统内存大小而不是resources.requests.memory. 后者只是让 Kubernetes 集群找到与请求的内存匹配的节点来在其上运行 pod。 其次,如前所述,heapJVM只能指定并严格控制内存的大小,而不能指定non/off-heap内存。因此,即使系统内存增加,non/off-heap内存使用量也可能成比例增加。 为了...

For the purposes of the Java programming language memory model, a single write to a non-volatile long or double value is treated astwo separate writes: one to each 32-bit half. This can result in a situation where a thread sees the first 32 bits of a 64-bit value from one write, ...
我参考的源码:GitHub-trung/InMemoryJavaCompiler Spring Bean 实例化 要将Config 类实例化成 Bean,我们可以在 xml 里预定义它,在编译结束后创建一个简易的 FileSystemXmlApplicationContext 实例化这个 xml 内的 Bean。 类加载器 首先要让 Spring 能够加载到这些编译好的字节码,这就需要 ClassLoader 的配合。类加...
