export.design(design, filename = output, type = "csv")

Makefile Generation

./doe_makefile_generate.pl $output.csv

Experiment execution

make -C $output
cat $output/*.txt > $output.txt

Output reformating

open INPUT, $input;
$output = $input;
$output =~ s/\.txt$/.csv/;
$output = "res_".$output;

open OUTPUT, "> ".$output;
while($line=<INPUT>) {
  if($line =~ /^platform: *(.*)$/) {
    $platform = $1;
  } elsif($line =~ /^run.no: *(.*)$/) {
    $run_no = $1;
  } elsif($line =~ /^optim: *(.*)$/) {
    $optim = $1;
  } elsif($line =~ /numflows: *(.*)$/) {
    $num = $1;
  } elsif ($line =~ /Elapsed time : *(.*)/) {
    print OUTPUT "$run_no, $platform, $num, $optim, $1\n";
  }
}
print $output

Typical R analysis

Whole run

Let's do a real set of experiments now down to the final plot.
