Abstract

IntelligentI/O is a rule based general model for performing "intelligent" processing of Input/Output operations in an Operating System. In a new interface layer between the applications and the kernel I/O functions, rules determine actions to be performed at I/O time which in turn invoke programs in user space. IntelligentI/O permits complete implementation in user space applications that would normally require ad-hoc kernel modifications such as a Network File System. It also serves to implement features that would normally have to be embedded in an application, such as Automatic Format Conversion or Revision Tracking. We later present SuperFile, a simple yet powerful existing implementation of the IntelligentI/O model, together with a number of applications developed using SuperFile.
