MemoryConstrained

MemoryConstrained[expr, b] evaluates expr, stopping if more than b bytes of memory are requested. MemoryConstrained[expr, b, failexpr] returns failexpr if the constraint is exceeded.

Examples

Limit memory usage:

MemoryConstrained[Range[10^8], 10^6]
(* $Aborted - requires too much memory *)

Provide fallback value:

MemoryConstrained[Range[10^8], 10^6, "Too much memory"]
(* "Too much memory" *)

Successful within limits:

MemoryConstrained[Range[100], 10^6]
(* {1, 2, ..., 100} *)
