Enter a model name: === Verification check vc-memory-leak start (2019-08-09 02:20:55) === !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!! !!!!! !!!!! VERIFICATION CHECK: vc-memory-leak !!!!! !!!!! !!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Description: Check that the model has no memory leaks. This is tested using the Valgrind memory debugging tool (http://valgrind.org) by performing a series of energy and force calculations on a randomly distorted face-centered cubic (FCC) cube base structure for both non-periodic and periodic boundary conditions. Separate configurations are tested for each species supported by the model, as well as one containing a random distribution of all species. Configurations used for testing are provided as auxiliary files.
