I issued the following command, but I don’t see a change on the node:

[root@smaster1 ~]# qmgr -c “s n compute-0-1 max\_running=1”  
[root@smaster1 ~]# pbsnodes compute-0-1  
compute-0-1  
Mom = compute-0-1.local  
Port = 15002  
pbs\_version = 14.1.2  
ntype = PBS  
state = offline  
pcpus = 40  
max\_running = 1  
resources\_available.arch = linux  
resources\_available.host = compute-0-1  
resources\_available.mem = 131744464kb  
resources\_available.ncpus = 40  
resources\_available.vnode = compute-0-1  
resources\_assigned.accelerator\_memory = 0kb  
resources\_assigned.mem = 0kb  
resources\_assigned.naccelerators = 0  
resources\_assigned.ncpus = 0  
resources\_assigned.netwins = 0  
resources\_assigned.vmem = 0kb  
resv\_enable = True  
sharing = default\_shared

[root@smaster1 ~]#

You can see this attribute set by running pbnsodes compute-0-1 | grep max\_running
