Interesting paper. One issue you haven't commented on in the paper is
compliance of GPUs to IEEE 754 floating point arithmetic standards. My
understanding is that GPUs tend to be non-compliant (see
http://www.cs.unc.edu/~ibr/projects/paranoia/). I've written a couple of
articles with my colleague Luis Izquierdo highlighting issues with
floating-point in ABM. Though IEEE 754 doesn't solve these issues, I suspect
non-compliance will make matters worse. This may only be important in
activities such as statistics processing, rather than the other facilities you
mention in your paper, but if even the storage of floating point numbers
doesn't follow IEEE 754 format, then using the colour bands to store properties
of agents and environments could also be risky...

Hello all,
I just wanted to share my latest publication in JASSS on ABM simulation on
the GPU. In this paper, we describe a framework designed to execute in a
data-parallel mannner on graphics processing units that is upto 3 orders of
magnitude faster than the state-of-the-art simulation toolkits.
