PaJFit
(Parallel Job Fit) is simple software for simulating the scheduling of
parallel jobs. It
has
a reduced set of
classes that can be modified according to the user needs. It has
been developed in Java without any special library. PaJFit can be
very useful for those who want something very simple for developing
scheduling algorithms and visualise the output.
For now, it supports jobs with hard deadlines and jobs with specified
starting time (advance reservations). Both types can be rigid or
moldable. Users can use both GUI and command line
(useful for scripts).
Important note: I have
been developed this software according to my research needs for my PhD
cadidature at University of Melbourne, Australia. Therefore, please do not
expect a very well designed
object-oriented framework for developing scheduling algorithms. It is not
a
product. However, I am making it available since other people may find
it useful. Of course, suggestions are very welcome ;-)

Version 0.3: This
version has
support for multi-site environments and has a lot of optimizations to
execute the simulations much faster. This version is
based on what I developed to perform the experiments of the report "A
Flexible Resource Co-Allocation Model based on Advance Reservations
with Rescheduling Support", 2007. I'm still refactoring some parts
of the source code and writing the documentation to improve the
usability of the simulator. So please, if you want to have the code in
the way it is now, just let me know.
Version 0.2: This version is
based on what I developed to perform the experiments of the paper "SLA-based
advance
reservations with flexible and adaptive time QoS parameters",
published in Proceedings of ICSOC'07. Here I mainly included support
for
flexible advance reservations and some other heuristics. For details,
please check the paper. Software:

Version 0.1: This version is
based on what I developed to perform the experiments of the paper "Impact of Adaptive Resource Allocation
Requests in Utility Cluster Computing Environments",
published in Proceedings of CCGRID'07. However, I simplified some
things. I mainly removed the job preemption because I thought it was a
bit complicated. I also included some support for advance reservations.
