Mistake in caculating Benchmark Average

There is a basic principal that you cannot average averages. The overall result for the benchmark should be calculated by dviding the sum of the target results by the sum of the baseline results. This is not the same as dividing the sum of the index results by 6. Changing the way this is calculated will give a more mathematically valid way of comparing performance from one host to the other.

NAME
Math::VecStat - Some basic numeric stats on vectors SYNOPSIS
use Math::VecStat qw(max min maxabs minabs sum average); $max=max(@vector); $max=max(@vector); ($max,$imax)=max(@vector); ($max,$imax)=max(@vector); $min=min(@vector); $min=min(@vector); ($max,$imin)=min(@vector); ($max,$imin)=min(@vector); $max=maxabs(@vector); $max=maxabs(@vector); ($max,$imax)=maxabs(@vector); ($max,$imax)=maxabs(@vector); $min=minabs(@vector); $min=minabs(@vector); ($max,$imin)=minabs(@vector); ($max,$imin)=minabs(@vector); $sum=sum($v1,$v2,...); $sum=sum(@vector); $sum=sum(@vector); $average=average($v1,$v2,...); $av=average(@vector); $av=average(@vector); $ref=vecprod($scalar,@vector); $ok=ordered(@vector); $ok=ordered(@vector); $ref=sumbyelement(@vector1,@vector2); $ref=diffbyelement(@vector1,@vector2); $ok=allequal(@vector1,@vector2); $ref=convolute(@vector1,@vector2); DESCRIPTION
This package provides some basic statistics on numerical vectors. All the subroutines can take a reference to the vector to be operated on. In some cases a copy of the vector is acceptable, but is not recommended for efficiency. max(@vector), max(@vector) return the maximum value of given values or vector. In an array context returns the value and the index in the array where it occurs. min(@vector), min(@vector) return the minimum value of given values or vector, In an array context returns the value and the index in the array where it occurs. maxabs(@vector), maxabs(@vector) return the maximum value of absolute of the given values or vector. In an array context returns the value and the index in the array where it occurs. minabs(@vector), minabs(@vector) return the minimum value of the absolute of the given values or vector. In an array context returns the value and the index in the array where it occurs. sum($v1,$v2,...), sum(@vector), sum(@vector) return the sum of the given values or vector average($v1,$v2,..), average(@vector), average(@vector) return the average of the given values or vector vecprod($a,$v1,$v2,..), vecprod($a,@vector), vecprod( $a, @vector ) return a vector built by multiplying the scalar $a by each element of the @vector. ordered($v1,$v2,..), ordered(@vector), ordered(@vector) return nonzero iff the vector is nondecreasing with respect to its index. To be used like if( ordered( $lowBound, $value, $highBound ) ){ instead of the (slightly) more clumsy if( ($lowBound <= $value) && ($value <= $highBound) ) { sumbyelement( @array1, @array2 ), diffbyelement(@array1,@array2) return the element-by-element sum or difference of two identically-sized vectors. Given $s = sumbyelement( [10,20,30], [1,2,3] ); $d = diffbyelement( [10,20,30], [1,2,3] ); $s will be "[11,22,33]", $d will be "[9,18,27]". allequal( @array1, @array2 ) returns true if and only if the two arrays are numerically identical. convolute( @array1, @array2 ) return a reference to an array containing the element-by-element product of the two input arrays. I.e., $r = convolute( [1,2,3], [-1,2,1] ); returns a reference to [-1,4,3] median evaluates the median, i.e. an element which separates the population in two halves. It returns a reference to a list whose first element is the median value and the second element is the index of the median element in the original vector. $a = Math::VecStat::median( [9,8,7,6,5,4,3,2,1] ); returns the list reference [ 5, 4 ] i.e. the median value is 5 and it is found at position 4 of the original array. If there are several elements of the array having the median value, e.g. [1,3,3,3,5]. In this case we choose always the first element in the original vector which is a median. In the example, we return [3,1]. =back =head1 HISTORY $Log: VecStat.pm,v $ Revision 1.9 2003/04/20 00:49:00 spinellia@acm.org Perl 5.8 broke test 36, exposing inconsistency in C<median>.
