Hi,

have you tried using the profiler?
oplrun -profile x.mod x.dat

I am using the profiler in the graphical interface. It's great! But I want to run a series of problems and record the memory consumed for each one. Right now I have to write the value by hand. It would be nice if I could automate this, write the value to file.

here is an undocumented way to do this while using oplrun.
When using oplrun -profile, the following example will output the profiler output in the scripting log, which you can redirect for example in a IloOplOutputFile.
This way, if you launch multiple sub problems, you will be able to see the memory consumption of each of them.

range r = 1..10; dvar int+ x[r] in 1..10;   execute PRE 
{ writeln(
"Hello PRE"); 
}   execute 
{ writeln(
"Hello"); 
}   subject to 
{ ct: sum(i in r) x[i] >= 0; forall(i in r) cts: x[i] >= i; 
}   execute POST 
{ writeln(
"Hello POST"); 
}     main 
{ thisOplModel.generate(); cplex.solve(); thisOplModel.postProcess(); 

static function printProfile(n,prefix) 
{ 

for(; n; n=n.next) 
{ writeln(prefix,
"n.name = ",n.name); writeln(prefix,
"n.section = ",n.section); writeln(prefix,
"n.time = ",n.time); writeln(prefix,
"n.selfTime = ",n.selfTime); writeln(prefix,
"n.peakMemory = ",n.peakMemory); writeln(prefix,
"n.localMemory = ",n.localMemory); printProfile(n.firstChild,prefix+
"  "); 
} 
} writeln(
"Profiler:"); printProfile(thisOplModel.settings._profilerRootNode,
"  "); 
}
