Java线程在哪个处理器上运行? [英] Java thread running on which processor?

问题描述

是否可以使用Java本机线程找出运行线程的处理器(在单个系统上还是在多个系统上)?如果没有，是否有任何图书馆可以帮助您?

Is there a way to find out which processor (either on a single system or mutliple systems) your thread is running on, using Java native threads? If not, is there any library which could help?

推荐答案

JVM的线程调度程序是特定于JVM的，因此没有通用"解决方案.据我所知，没有可用的现成可用，而是使用:

The JVM's thread scheduler is JVM-specific, so there is no 'universal' solution. As far as I know there is nothing available out-of-the-box, but perhaps using:

• Sun JVM；
• Solaris-或Mac，如 Tom Hawtin-粗线所指出；
• DTrace .

• the Sun JVM;
• Solaris - or Mac, as Tom Hawtin - tackline points out;
• DTrace.

您可能会有些运气:

• 跟踪thread-start探针，其探针为args[3]本机/OS线程ID.这是由主机操作系统分配的ID"
• 使用Solaris特定的实用程序将本机/OS线程ID映射到CPU.

• trace a thread-start probe, which has as args[3] the "The native/OS thread ID. This is the ID assigned by the host operating system "
• map the native/OS thread ID to a CPU, using Solaris-specific utilities.
