Cromwell runtime 'memory' units
In WDL you can specify which unit your 'memory' runtime parameter is in. eg M, G, but also whether you are using binary or base 10 units (1024 vs 1000).
Cromwell consumes this parameter, and you can request the parameter as M or G, eg memory_gb memory_mb. However the docs do not state if that uses base 10 or base 2. Actually I could not find the documentation of that memory_x at all, maybe I read it in a tutorial not the actual docs.
Is it possible to specify the base? What units are possible?
