==== Description: ====
ARSim is a simulator for adaptive reservations that has been developed at the
Real-Time Systems Laboratory (ReTiS) of Scuola Superiore Sant'Anna, Pisa
(Italy) for simulations relative to research papers.
It may be used for the purpose of emulating a system in which physical
resources are shared among different concurrently running applications, and
the low-level scheduling algorithm adopted by the OS to assign each resource
to the applications in each available time-slice may be reasonably abstracted
away as a "fluid model". This is a model in which one can rely on a
"bandwidth" or "resource share" abstraction, in which each application
temporal behavior in accessing the resource may be approximated as the one
resulting from having, for each application, a dedicated resource that is
slower than the physical actual resource by a factor equal to the allocated
"bandwidth" or "share". Such a model is commonplace for QoS evaluation and
performance estimation, as done in the real-time research community when
dealing with soft real-time systems.
By Adaptive Reservations we mean an allocation scheme in which the percentage
of resource available to each application may be dynamically varied at
run-time, based on application requirements.
ARSim embeds a modular and expandable architecture, in which different models
for task behaviors are available for the simulation, ranging from
stochastic-based models to models that simply read data from a trace input
file. Also, different types of resource allocation controllers are available
ranging from ones based on a deterministic/WCET-based design, to ones based
on a stochastic/probabilistic design.
Also, new components may be easily added into the framework by defining new
classes that implement the top-level interfaces.
Currently, the source-code (under a GPL license) is available at the
following URL:
