Multimedia applications are increasingly populating the workstation
desktop. However, operating systems lack the necessary resource
management mechanisms and interfaces to support the real-time
requirements of these applications. To address this problem, I created
SMART, a Scheduler for Multimedia And Real-Time applications.  SMART
supports both real-time and conventional computations and provides
flexible and accurate control over the allocation of processor time.
I have implemented SMART in the Solaris UNIX operating system and
measured its performance. 

In this talk, I will present the design and implementation of SMART,
describe how SMART helps to reduce the burden of developing
applications with real-time constraints, and present some experimental
measurements that quantitatively compare SMART versus other schedulers
in executing real-time, interactive, and batch applications. The
results demonstrate SMART's effectiveness in supporting multimedia
applications.
