3/9/2024 0 Comments What does qw mean in sge queueUsers are not allowed to ssh or rsh from the login host directly to a compute node. Running interactive jobs on cluster nodes You will lose any data and/or computations associated with the running job. Any compute-intensive jobs found running on a login node will be KILLED WITHOUT NOTICE. Rather, it is ONLY for text editing and for submitting jobs to the cluster. Do NOT run jobs on jhpce01! This machine is not for doing any sort of computation. The logon machine ( jhpce01/jhpce02) is only used for login. When the cluster nodes are all at maximum capacity, jobs waiting to run will be subject to a functional share priority algorithm. ![]() You may submit jobs which request more than your slot limit and they will all be queued to run as your other jobs finish. The Grid Engine project was sponsored by Sun Microsystems as an open source community effort to facilitate the adoption of distributed computing solutions.īy default, one job uses one slot, but see Requesting multiple SGE slots for a multi-core job. To obtain an account on this machine, please refer to the instructions at Įverything related to job submission, scheduling, and execution on the cluster is under the control of Sun Grid Engine (SGE). The cluster can be accessed via the machine jh. Currently these are optional but they will soon be required, so we recommend that you set up one or both of these immediately.Ĭonfigure key-pair authentication: key-pair authenticationĬonfigure 2-factor authentication: 2-factor authentication Using the cluster Don’t believe us? Read this scary article from wired magazine. We prefer that you use key-pair authentication for logins from your normal machine or 2-factor authentication when logging in from any other machine. Setting up keypair and 2-factor authentication ![]() Requesting multiple SGE slots for a multi-core job.Notes about specifying resource requirements.A special note about h_vmem and h_stack.Using a default SGE specification file.Two steps to submitting an R BATCH job to the cluster.Submitting batch jobs from the login node.Running interactive jobs on cluster nodes.The information below is no longer relevant in JHPCE, but is being retained for historical purposes. We are building out a new web site which will be be made specifically for the new SLURM environment. Most of what is documented below can be found in the updated orientation slides, which can downloaded at: The information below is largely SGE specific and likely not relevant. ![]() UPDATE – – The JHPCE Cluster has been recently migrated from SGE to SLURM.
