摘要

多媒体应用具有动态、自适应的实时性要求。以UNIX System V Release 4为代表的当前调度实践缺乏满足这些需求的必要信息和接口。为了解决这个问题，我们创建了SMART(多媒体和实时调度程序)接口。它显式地考虑了特定于应用程序的时间限制，并从调度器向应用程序提供动态反馈，使它们能够适应系统负载条件。本文介绍了该接口的设计及其在Solaris UNIX操作系统上的实现，为支持多媒体应用提供了一个有效的符合svr4的全功能环境。

SMART UNIX SVR4 support for multimedia applications

Multimedia applications have dynamic and adaptive real-time requirements. Current scheduling practice, as typified by UNIX System V Release 4, lacks the necessary information and interfaces to meet these requirements. To address this problem, we have created the SMART (Scheduler for Multimedia And Real-Time) interface. It explicitly accounts for application-specific time constraints and provides dynamic feedback from the scheduler to applications to allow them to adapt to the system loading condition. This paper describes the design of the interface and its implementation in the Solaris UNIX operating system to provide an effective SVR4-conformant full featured environment for supporting multimedia applications.
