因此用户不能直接访问内核。虽然通过调用系统提供的 API（应用程序编程接口）就能实现 某个功能，但哪怕实现“将一条信息通过互联网传输给别人”这样简单的任务，都要手动调 新手必须掌握的 Linux 命令 66 用几十次 API 接口，使用起来太不切实际。而最外层的服务程序则是最贴近于用户端的，这 些服务程序是集成了大量 API 接口的完整软件，微信、QQ 就是这样的服务程序。 易、腾讯等门户网站的青睐。本书将在第 20 章讲解 Nginx 服务程序。 Apache 程序是目前拥有很高市场占有率的 Web 服务程序之一，其跨平台和安全性广泛被 认可且拥有快速、可靠、简单的 API 扩展。图 10-2 所示为 Apache 服务基金会的著名 Logo， 它的名字取自美国印第安人的土著语，寓意为“拥有高超的作战策略和无穷的耐性”。Apache 服务程序可以运行在 Linux httpd_can_connect_ftp --> off httpd_can_connect_ldap --> off httpd_can_connect_mythtv --> off httpd_can_connect_zabbix --> off httpd_can_network_connect --> off httpd_can_network_connect_cobbler --> off httpd_can_network_connect_db

Management），提供了异构内存互联的中心化管理机制，且 GMEM API 与 Linux 原生内存管理 API 保持统一，易用性强，性能与可移植性好。 加速器使用 GMEM API 将内存接入统一地址空间后，可自动获得 GMEM 面向异构内存编程优化的能力。与此同时，加 速器驱动无需重复实现内存管理框架，大幅降低开发维护带来的成本。 开发者使用一套统一申请、释放的 API，即可完成异构内存编程，无需处理内存搬移等细节。在加速器 r 内存消息交互框架提供了设备接入抽象层。在统一的地址空间下，GMEM 可以在数据需要被访问或换页时，自动地迁移数 据到 OS 或加速器端。 功能描述 Host Device GMEM API Process Main Remote Pager GMEM( 异构内存 ) GMEM Remote Pager GMEM( 异构内存 ) Co-process 统一虚拟地址空间 mmap/hmadvise 机与加速器进行搬移。在实际使用时，加速器可在内存不足时可以借用主机内存，同时回收加速器内的冷内存，达到内存 超分的效果，突破模型参数受限于加速器内存的限制，实现低成本的大模型训练。 通过在内核中提供 GMEM 高层 API，允许加速器驱动通过注册 GMEM 规范所定义的 MMU 函数直接获取内存管理功能， 建立逻辑页表并进行内存超分。逻辑页表将内存管理的高层逻辑与 CPU 的硬件相关层解耦，从而抽象出能让各类加速器复

unified management of both containers and node OS through Kubernetes, including atomic upgrades and API-based operations. Challenges In cloud-native scenarios, containers and Kubernetes are widely used status before the OS changes to implement collaborative scheduling of service containers and OSs. • API O&M: Kubernetes-native declarative APIs are used to manage and maintain OSs in a standard manner. devices, especially for devices that have certain restrictions on power consumption. • Difficult API adaptation: There are no unified APIs that mask differences in underlying hardware and networking,
