Some Software I wrote...

Research

I participated in the development of the HARTIK kernel, implementing a CBS scheduler in it, and developing some device drivers.
The HARTIK development is no more active (see SHaRK for the most recent development branch). Here you can find a version of HARTIK that I maintain, and that provides a simpler building system and some bugfixes.
I developed a QoS manager implementing Adaptive Bandwidth Reservations, as described in ``Adaptive Bandwidth Reservation for Multimedia Computing'', by myself and Giorgio Buttazzo (see my publications page).

Software

HARTIK

The HARTIK development stopped some time ago, when SHaRK became stable. However, I still use HARTIK for some experiments, and it is one of the kernels on which I run adaptive reservations (the other one is Linux/RK). For this reason, I maintain a version of the HARTIK kernel, presenting some improvements respect to the original one (mainly, some bugfixes and an improved building system. Moreover, the latest HARTIK release changed some function names and syntaxes respect to my one).

This version of HARTIK can be compiled on DOS (using DJGPP V1 and V2 -- I don't support Watcom anymore) or linux systems. In order to install it, download the file h050701.zip, unzip it with unzip -a h050701.zip, enter in the hartik, and copy the correct configuration file from the mk directory: copy mk\djv1.mk config.mk or copy mk\djv2.mk config.mk for DOS, or cp mk/linux.mk config.mk. Then, you can type m all for DOS, or make all for Linux. After that, you can build an example entering in the examples directory and typing, for example, make APP=aster.

Please, mail me for any kind of problem.

The QoS Manager

The QoS manager implementing the Adaptive Reservation abstraction is distributed together with some other software, such as a MultiMedia demo for HARTIK and a port of the MPEG library (used for all my experiments).

In order to install the package containing all these programs, download y050701.zip, and decompress it with unzip -a y050701.zip on a DOS or linux system. The following directories will be created:

yamme is a directory containing all the other ones
include contains the header files for all the provided libraries
mpeg_pla contains a port of the MPEG library, based on the Berkeley MPEG player
qosman contains the original QoS manager developed for HARTIK. Note that this directory will be eliminated when all the QoS Manager code will be included in the portable implementation (see qoslib)
qoslib is a portable reimplementation of the QoS Manager, also included in the latest Linux/RK distribution. I am currently working on porting all the qosman code in this directory
mmdemo a MultiMedia demo for HARTIK, mixing some video, audio, and control applications
examples some example programs, using the MPEG library and the QoS manager.

In order to compile everything, you need to unzip h050701.zip and y050701.zip in the same directory. After that, enter in the hartik directory to configure and compile HARTIK as shown above. Then, you can finally compile the QoS manager and the other libraries and demo by simply entering in their directories and typing make or make APP=<program_name>.

Unfortunately, most of this material is still undocumented; some preliminary documentation about the portable QoS Manager can be found here. Please, let me know if you need more information.
