In a previous article, we put together a list of10 useful commands to collect system and hardware information in Linux. In this guide, we will narrow down to the CPU/processor, and show you various ways of extracting detailed information about your machine CPU. Just to give you an overview...
例如,getrusage 是一个常用的系统调用,它能够获取到当前进程的资源使用情况,这在Linux内核源码的 kernel/resource.c 文件中有具体实现。 1.2.1 getrusage系统调用 getrusage 系统调用提供了一种机制,允许开发者直接获取到进程的资源使用情况,包括 CPU 使用时间、页面错误次数、上下文切换次数等。这些信息对于分析程序的...

具体请参见dcmi_set_device_cpu_num_config接口原型。 buf_size 输入 unsigned int buf长度,buf_size参数固定配置为16。 返回值 类型 描述 int 处理结果: 成功:返回0。 失败:返回码请参见返回码。 异常处理 无。 约束说明 表3-22 部署场景 Linux物理机 Linux物理机容器 root用户 运行用户组(非root...
4:控制CPU 5:内存带宽 6:片上内存 8:DDR 10:片上内存带宽 12:vector core 说明: 当设备类型为AI CORE或vector core时开启profiling,查询占用率为0,实际无意义。 utilization_rate 输出 unsigned int * 处理器利用率,单位:%。 说明: 当设备类型为内存时,utilization_rate输出值为-1,无实际意义。

在linux主机下执行 lscpu 命令,可以得到如下结果: $ lscpu | grep -i'core.*:|socket' Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 1 意思是我的linux主机有 1 个 cpu,每个 cpu 的核心有 2 个,每个核心支持 2 个线程。那么在进行多线程编程的时候,如何为某个线程指定 cp...
3. 进程与CPU的绑定 在Linux中,用结构体cpu_set_t来表示CPU Affinity掩码,同时定义了一系列的宏来用于操作进程的可调度CPU集合: #define _GNU_SOURCE #include <sched.h> void CPU_ZERO(cpu_set_t *set); void CPU_SET(int cpu, cpu_set_t *set); ...
The above output displays CPU architecture, number of CPUs, cores, CPU family model, threads, CPU caches and much more. Get Block Device Information with lsblk The lsblk utility displays information about all the basic storage devices of your system such as hard drive, its partitions and the ...
