The Active Block I/O Scheduling System (ABISS) is an extension of the hard-disk storage subsystem of Linux, whose main purpose is to provide a guaranteed reading and (eventually) writing bit rate to applications.
ABISS is conducted by Philips Research in Eindhoven, the Netherlands (see http://www.research.philips.com/technologies/storage/index.html). http://abiss.sourceforge.net/abiss-7.tar.gz md5sum 081abbfa1d11ce268dab300576edc194 sha1sum 7851ebd768fc1a96207836b5189450c90e4ddd05 This release upgrades ABISS to the 2.6.11 kernel, brings some major cleanup and introduces experimental support for writing with a guaranteed rate. The highlights: - the "allocator" functionality has been completely removed. It represented a very complicated way for doing things that can be done much more efficiently and cleanlier in the file system driver, complicated the inner workings of ABISS, and wasn't of much use in its present state anyway. - removed the abiss_detach message, which was a no-op - this release adds an experimental mechanism for delayed allocation of file blocks. In its current form, this is mainly intended for exploring performance aspects, and may have yet undiscovered fascinating bugs. This may also be of interest for a broader audience, hence the cross-posting to linux-fsdevel. - ABISS now tries to guarantee the accepted data rate also when writing. For now, this only works for FAT and ext2, and when delayed allocations are enabled. All this is still very experimental and only works most of the time.
