dopNet debug the performance - some question


Recommended Posts


I've some question about the dopNet, and the memory performance:

I currently query the memory used in the simulation in this way

def memConsumed():
        sim = hou.node("../.").simulation()
        return "%s" %(str(hou.DopSimulation.memoryUsage(sim)*0.000001))
        return "NONE"
sys.stderr.write("\nMEM CONSUMED :   %s MB" %(memConsumed()))

A) Is working but the memory usage is quite different off from the memoryGrowth on the performance profile, is this last on reliable for the dopNet?
B) I'm looking some method to go more in deep, I saw every object have record of the memusage, but unfortunately this one is not the sum of every child dependency in the network, example:

memmoryUsage(x) = 10000000000

SIM_Objcet                           > 100
    SIM_SolverMulti              > 150
        SIM_SolverSop(01)    > 75
        GAS_SubStep          > 5000
            ...          > 30
            ...          > 999999
        SIM_SolverSop(02)    > 350  

It may have sense to check the "self memory consumed", but in a debug prospective this is not really efficient IMHO
Is there anyway to  have the memusage  as a sum of the relative child?

C) are there any record field to describe if any gas solver is multi thread or not? right now the only way that I've is tun a profile and check rolling over for each micro-solver.

D) any way to read the time usage for each node? (without dealing with the infoTree, I was expecting sidefx putting a field in the basic record for that like memusage )

E) there is anyway to append the profile file .hperf frame by frame? right now I'm saving a profile by stubstep

so far this is my output

Profiler stopped and archived
Profiles saved: /xxxxx_20180904_10_51_19/14.25.hperf

(note the field are a list of interested one)
I still need to work to read the solver process and collect all the info to process a % print
