Trying to solve a differential equation numerically, I noticed that Mathematica used up all RAM to the extent that my operating system (Windows 10) lost responsiveness and hung up.



As a result I had to restart my machine, losing all unsaved progress in the Mathematica notebook I was working on.




Is there a way to limit the RAM amount Mathematica can possibly access during a calculation?

    You can use MemoryConstrained to constrain the amount of memory a computation takes.

    @CarlWoll Thanks! I wonder if there is a setting that applies this to the entire kernel session?

You can use MemoryConstrained to set a memory constraint for an evaluation. You can use $Pre to set a memory constraint for all evaluations:



$Pre = Function[
Null,
MemoryConstrained[#, 2000000000-MemoryInUse[]],
HoldAll
];


For example:



Range[10^9]



$Aborted
