Detailed Description
Timer class, assumed to be an attribute of engineering model, serving stop-watch facility for engineering model.
It can handle several timers independently, each corresponding to different solution stage, etc. Each timer is capable to track elapsed wall clock time as well as user time.
Member Enumeration Documentation
Enumeration to distinguish different type of timers.
EMTT_NetComputationalStepTimer timer (and particularly its wall clock time) should measure only computation itself, no communication, therefore it should be measure of workload (in terms of wall clock time) on particular processors. It also typically not include time needed to solve the system of equations, since this has to be done in parallel, so solution takes the same time on all processors and include unwanted synchronization.
