The Institute for Environmental Modeling (TIEM), based in the Department of Ecology 
and Evolutionary Biology, maintains what is likely the finest computational
facilities associated with any research and graduate program in computational 
ecology in the US. This includes an extensive networked collection of
UNIX workstations and a 14-processor Symmetric MultiProcessor (SMP) with 10 GB of
RAM and over 800 GB of fast-channel access disc storage. The SMP is a 
Sun Microsystems Enterprise 4500 and as configured is the most powerful 
computer we are aware of dedicated for use in computational ecology anywhere
in the world. The SMP is part of the SInRG (Scalable Intracampus Network Grid)
project at UT funded with support from the National Science Foundation. The 
availability of a variety of other Grid Clusters through SInRG provides 
an extensive collection of heterogeneous computing resources for computational
ecology in addition to the SMP. For details on SInRG see
