You are right that I mistakenly thought I was running the gnu time program when I was really using the bash time argument. Am I right in guessing that this reports the time it takes the bash command to execute and not the time it takes the program to run, or is there a difference?

GNU time gives more detailed output, such a page faults, etc. I thought I tried /usr/bin/time at some point, but that didn't work. I will have to give that a try and see if I can get it working. Which says that it's there. One of the issues I as thinking of is that the log file already exists, so I would want -a, but I didn't know if I could do -a without first having used -o to create the file.

This is the current version of the script,
Code:
#!/usr/bin/bash

# t value
TIMEOUT=1000
# n value
NCLIENTS=4

echo "testing output" > test_times.txt
echo "" >> test_times.txt

# list input file sizes here (number of compounds)
SIZE=( 1K 10K 100K 500K 1M )

for SIZE in ${SIZE[@]}
do
   echo "Runtimes for servlet 4," $SIZE "structures" >> test_times.txt
   echo "" >> test_times.txt

#  list values for N here
   CPDS=( 10 100 500 1000 2500 5000 10000 25000 50000 75000 100000 )

   for CPDS in ${CPDS[@]}
   do
      echo "Runs where N="$CPDS >> test_times.txt 

#     list number of repetitions for each run
      REP=( 1 2 3 4 5 )

      for REP in ${REP[@]}
      do
         echo 'run' $REP 'test_ActiMol_'$SIZE'.sdf -n 4 -t 1000 -l 100 -d t -N' $CPDS >> test_times.txt 
         ( time ./servert.exe -n $NCLIENTS -t $TIMEOUT -l 100 -d t -N $CPDS \
           -i  'test_ActiMol_'$SIZE'.sdf' \
           -o  'test_ActiMol_'$SIZE'_'$CPDS'N_'$REP'.s' ) >> test_times.txt 2>&1

         echo "TIMEOUTS=" $(grep -c "TIMEOUT" 'test_ActiMol_'$SIZE'_'$CPDS'N_'$REP'.s') >> test_times.txt
         echo "SEGFAULTS=" $(grep -c "SEGFAULT" 'test_ActiMol_'$SIZE'_'$CPDS'N_'$REP'.s') >> test_times.txt
         echo "NUMBER PROCESSED=" $(wc -l 'test_ActiMol_'$SIZE'_'$CPDS'N_'$REP'.s') >> test_times.txt
         echo "" >> test_times.txt

#        print something to the terminal to monitor progress
         echo 'completed run' $REP 'test_ActiMol_'$SIZE'.sdf -n' $NCLIENTS '-t' $TIMEOUT '-l 100 -d t -N' $CPDS

      done
      echo "" >> test_times.txt 

   done
      echo "" >> test_times.txt
      echo "" >> test_times.txt 

done

unix2dos test_times.txt

It seems as if some of the multiple echo statements could be reduced using the here-document that Corona688 suggested. I will look into that. It also seems that I could echo a couple of newlines at once instead of doing it several times to insert several blank lines.
