→Billing units formula: change GPU multiplier
<pre>
BillingHours = MAX( CPUs, RAM_GB * 0.215, GPUs * 3531.0 81818 ) * hours
</pre>
One of our '''GPU-equipped nodes''' has 40 CPUs, 186G of RAM, and two GPUs. To use that node for 24 hours would cost
MAX( 40, 186*0.215, 2*35 31.81818 ) * 24 = 70 63.636 * 24 = 1680 1527 billing hours.
The rate per GB of RAM is chosen so that using either all the CPUs or all the RAM on a basic node costs the same 40 billing units.
In this example, the billing rate is 40 and the elapsed time is 2 minutes 9 seconds, or 0.0358 hours,
so the job cost 1.43 billing hours.
(The multiplier for GPU hours was changed from 35.0 to 31.81818 on 2024-04-16.)
