<p><b>New page</b></p><div>Please record useful notes about the new SiCortex machine here. <br />

== Specifying nodes ==<br />
A node specific hello world program:<br />
<pre><br />
$ cat hosthello.c<br />
<br />
#include <unistd.h><br />
#include <stdio.h><br />
<br />
int main()<br />
{<br />
char name[100];<br />
gethostname(name, sizeof(name));<br />
printf("%s says hello!\n", name);<br />
return 0;<br />
}<br />
</pre><br />
Compile<br />
<pre><br />
$ gcc hosthello.c -o hosthello<br />
</pre><br />
and run one process (-n1) on one node (-N1) named sca-m0n10 with<br />
<pre><br />
$ srun -p sca -N1 -n1 -w sca-m0n10 ./hosthello<br />
<br />
sca-m0n10.scsystem says hello!<br />
</pre><br />
Run two processes (-n2) on two specific nodes (-N2), sca-m0n10 and sca-m0n11, with<br />
<pre><br />
$ srun -p sca -N2 -n2 -w sca-m0n10,sca-m0n11 ./hosthello<br />
</pre><br />
<pre><br />
sca-m0n10.scsystem says hello!<br />
sca-m0n11.scsystem says hello!<br />
</pre><br />
