Dealing with the Linux OOM Killer at the program level

Do this in cases when you dont want to change the os-level settings, but only want to disable the OOM killer for a single process. This is useful when youre on a shared machine/server.

The OOM killer uses the process level metric called oom_score_adj to decide if/when to kill a process. This file is present in /proc/$pid/oom_score_adj. The oom_score_adj can vary from -1000 to 1000, by default it is 0.

You can add a large negative score to this file to reduce the probability of your process getting picked and terminated by OOM killer. When you set it to -1000, it can use 100% memory and still avoid getting terminated by OOM killer.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

C99 List of Undefined Behavior

From N1256: (See http://port70.net/~nsz/c/c99/n1256.html#J.2)

A "shall" or "shall not" requirement that appears outside of a constraint is violated (clause 4).
A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2).
Token concatenation produces a character sequence matching the syntax of a universal character name (5.1.1.2).
A program in a hosted environment does not define a function named main using one of the specified forms (5.1.2.2.1).
A character not in the basic source character set is encountered in a source file, except in an identifier, a character constant, a string literal, a header name, a comment, or a preprocessing token that is never converted to a token (5.2.1).
An identifier, comment, string literal, character constant, or header name contains an invalid multibyte character or does not

	You need the terminal color codes. For linux it's the following (your system might be different, look it up):

	//the following are UBUNTU/LINUX, and MacOS ONLY terminal color codes.
	#define RESET "\033[0m"
	#define BLACK "\033[30m" /* Black */
	#define RED "\033[31m" /* Red */
	#define GREEN "\033[32m" /* Green */
	#define YELLOW "\033[33m" /* Yellow */
	#define BLUE "\033[34m" /* Blue */
	#define MAGENTA "\033[35m" /* Magenta */
