Moved epcc and amsmath package inclusions into packages section, put amsmath before hyperref.
Changed log_vs_log_sqrt_p plot from using bash to pure gnuplot by using 'system()' call. Updated log_vs_log_sqrt_p to show several sums of those two terms. Added replicated_systolic_comm_fits to fit the comm times to the log_vs_sqrt_p plots.
Poked at replicated_systolic_loop.tex.
