In this case it’s when the job (b)egins, (e)nds or is (s)uspended. This changes it to what ever you put for “Name” (“-N foo” would name the job foo). N Normally SGE names your job after your submit script. This tells it to use your current directory instead. Qsub Options -cwd SGE assumes all scripts run from / or $HOME. Takes a script file as an input4 In the scripts qsub flags begin with #$ and are generally optional. It also handles all of the queuing and scheduling. It provides the commands: qsub qrsh qstat qdel Running Jobs The Sun Grid Engine (SGE) is installed on the grid. 20% of each groups’ nodes are added to the common pool, and the rest they get to have exclusive access to. As a “tax” for IT to maintain the hardware, software, cooling, etc. That I have access to? Nodes are added to the grid by research groups that purchase them. Only 1, what if I want more? More on that later. Getting to a Node the Right Way Issuing the command “qrsh” on hnode will give you a shell with 1 CPU on any available host you have access to. If you’re wondering how complete: it’s the same no as mentioned for running jobs on hnode, but without the exceptions.īut if I can’t use SSH how do I get to a node? qrsh Getting to a Node So I just ssh to any node I want? No. So I’m logged in and want to compile and run a project for my research/class. So I’m logged in and I want to compile on a compute node. Getting Stuff Done So I’m logged in and I want to compile on hnode. Now What? I see “ ]$” so now what? I don’t know, that’s up to you. This will tend to be incredibly slow if you’re not on campus, and sometimes even if you are. X forwarding to use gedit, gvim, XEmacs or whatever other graphical editor you like3. Here’s the kind of things that are allowed on hnode: Small, < 5 second, compiles. So What’s hnode for? That not up there isn’t completely inclusive. To clarify: This means under no circumstances, never, not just once, not because you’re in a hurry, not because people are hogging the nodes. Everyone has to log in and work on this node, so be sure to play nice. More on this later.ĭo NOT12 run your jobs here. Or consider compiling your code somewhere else. Feel free to write and compile your code here. If you dont have these talk to the help desk at the lab in the KC for help. Logging In Hostname: Username: NetID Password: NetID Password
