			A node specific hello world program:
			<pre>
			$ cat hosthello.c

			#include <unistd.h>
⚫	http://www-theor.ch.cam.ac.uk/IT/servers/zippo/
			#include <stdio.h>

			int main()
			{
			char name[100];
			gethostname(name, sizeof(name));
			printf("%s says hello!\n", name);
			return 0;
			}
			</pre>
			Compile
			<pre>
			$ gcc hosthello.c -o hosthello
			</pre>
			and run one process (-n1) on one node (-N1) named sca-m0n10 with
			<pre>
			$ srun -p sca -N1 -n1 -w sca-m0n10 ./hosthello

			sca-m0n10.scsystem says hello!
			</pre>
			Run two processes (-n2) on two specific nodes (-N2), sca-m0n10 and sca-m0n11, with
			<pre>
			$ srun -p sca -N2 -n2 -w sca-m0n10,sca-m0n11 ./hosthello
			</pre>
			<pre>
			sca-m0n10.scsystem says Hello!
			sca-m0n11.scsystem says Hello!
