[gold-users] Question regarding gquote and goldsh ChargeRate Create

We are just starting to look at Gold to manage our allocations at NCAR
in Boulder, Colorado.
This is what I was trying to do...
Currently the accounting unit GAU is calculated for our Bluefire system as
|GAUs charged = wallclock hours used * number of nodes used * number of
processors in that node * computer factor * queue charging factor
where computer factor = 1.4 and queue charging factor = type of queue.
This is how I have loaded up our charges
goldsh ChargeRate Query
Type Name Rate Description
---------------- -------------- ---- -----------
Resource Processors 1
QualityOfService ComputerFactor 1.4
QualityOfService Capability 1
QualityOfService Economy 0.5
QualityOfService Hold 0.33
QualityOfService Premium 1.5
QualityOfService Regular 1
QualityOfService Standby 1
Using the above, I can use the gquote to get close to the output of this
simple charging algorithm...
gquote -p aircraft -u bertie -m lightning -P 32 -t 3600 -Q Economy -X

I am having a problem getting gold to multiply in the ComputerFactor of
1.4. The rest of the equation is working
||wallclock hours used * number of nodes used * number of processors in
that node * ||queue charging factor
The computer factor is just a factor placed into the equation based on
the speed of the machine when compared to the speed of a machine used as
the standard (i.e. 1)
When I use the -X option in the gquote for the ComputerFactor this is
just a guess on my behalf. I am not at all clear from the Gold
documentation as to what exactly the -X --extension option really does?
In order to implement this charging equation stated above, would we need
to modify the code of Gold?
Any insight that you might have would be greatly appreciated.
