Class
Foam::cpuLoad
Description
Class to maintain a field of the CPU load per cell.
The optionalCpuLoad is a base-class for cpuLoad to simplify the
implementation of optional CPU time caching. This is achieved via the
optionalCpuLoad::New function which returns a optionalCpuLoad with dummy
functions if loadBalancing is false otherwise it creates or looks-up and
returns a cpuLoad with the given name.
Used for loadBalancing.
