Unable to compile sample SOP with hcustom 2020年2月24日12:36

Houdini doesn't like the dll, can't catch any error but it's not loading it,
I suppose visual studio 2019 is not matching with Houdini 18,

this table is not really clear to me, I'm downloading visual 2017 and see if its gonna work

Unable to compile sample SOP with hcustom 2020年2月24日6:25

Same Dummy problem here:
try hard to understand witch mvs have to use,
atm win 8, Houdini 18.0.348 Apprentice

set MSVCDir=“C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.24.28314”
C:\Program Files\Side Effects Software\Houdini 18.0.348\bin\hcustom.exe" geo2voxel.C


receiving the error: MSVCDir incorrect environment variable - check iostream exist (and it does)

Update:
I had a misspelling, now is working

dopNet simulation.memusage() and memory performance 2018年9月3日9:32

Hi,

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

I currently querying the memory used in this way

def memConsumed():
    try:
        sim = hou.node("../.").simulation() 
        return "%s" %(str(hou.DopSimulation.memoryUsage(sim)*0.000001))
    except:
        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:

memoryUsage(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 reporting the value with the summing of the child value?

C) There are any record field that describe if any gas solver is multithreaed or not? right now the only way that i find to see is is to turn on a profile and check rolling over for each microsolver.

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 file for each stub-step

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




thanks,
Simone.
