+=====Interactive Job=====
+The login nodes are not for any substantive computation, including compiling.  Instead, request an //interactive job// through the PBSPro scheduler:
+<code>
+qsub -I
+</code>
+You will then see (after a short delay) a display similar to:
+<code>
+login2:~$ qsub -I -q serial -l select=1:ncpus=12:mpiprocs=12 -P WCHPC
+qsub: waiting for job 2665052.sched01 to start
+qsub: job 2665052.sched01 ready
+cnode0040:~$
+</code>
+Note that you are now connected to a //compute node// as indicated by the prompt: you are on ''cnode0004'' and all commands you run will execute on this compute node and **not** on the ''login2'' node.
