Almost all of the current process scheduling algorithms which are used in
modern operating systems (OS) have their roots in the classical scheduling
paradigms which were developed during the 1970's. But modern computers have
different types of software loads and user demands. We think it is important to
run what the user wants at the current moment. A user can be a human, sitting
in front of a desktop machine, or it can be another machine sending a request
to a server through a network connection. We think that OS should become
intelligent to distinguish between different processes and allocate resources,
including CPU, to those processes which need them most. In this work, as a
first step to make the OS aware of the current state of the system, we consider
process dependencies and interprocess communications. We are developing a
model, which considers the need to satisfy interactive users and other possible
remote users or customers, by making scheduling decisions based on process
dependencies and interprocess communications. Our simple proof of concept
implementation and experiments show the effectiveness of this approach in the
real world applications. Our implementation does not require any change in the
software applications nor any special kind of configuration in the system,
Moreover, it does not require any additional information about CPU needs of
applications nor other resource requirements. Our experiments show significant
performance improvement for real world applications. For example, almost
constant average response time for Mysql data base server and constant frame
rate for mplayer under different simulated load values. |
