Tiny command-line util that simulates lack of RAM by consuming memory in small chunks

simleak

Simulates a memory leak by consuming memory in small chunks. Suitable for testing performance and behavior of software in cases of having almost no available RAM.

Tested on macOS only so far, but build for Linux is coming.

Installation

As of now, there's no way to avoid building (which is quite simple though). Just clone the repo, run make build and you'll get the binary in target/build/simleak. Before running the command, make sure you have g++ and make installed.

Use

$ simleak -h
Simulates a memory leak by consuming memory in small chunks

  simleak [OPTION...]

  -m, --memory-limit arg  Sets memory limit in MBs (default: 32768)
  -c, --chunk-size arg    Sets chunk size in MBs (default: 32)
  -v, --verbose           Enable verbose execution log
  -z, --fill-with-zeroes  Fill the allocated memory with zeroes instead of
                          random values (faster)
  -h, --help              Print this help message
