You can run a simple example by copying the directory 

~mheroux/Trilinos/test/petra_power_method

and setting the following environment variables

setenv TRILINOS_HOME /home/u/mheroux/Trilinos
setenv TRILINOS_ARCH SOLARIS
setenv TRILINOS_COMM SERIAL

Then type "make" in the petra_power_method directory.

Running "petra_power_method 100"  will generate a tridiagonal 
matrix of dimension 100 and find the largest eigenvalue via the 
power method.
