One of 91르적 Advanced Research Computing group’s partners, the Ohio Supercomputing Center (OSC) will switch to Slurm for job scheduling and resource management on the Owens cluster during the December 15 downtime.\u00a0OSC highly recommends that all members of the client community test their workflow in the Slurm environment before the migration to avoid any interruptions to their work.<\/p>\n
Slurm has a completely different command line interface from Torque\/Moab, which is the current job scheduler and resource manager used on the Owens cluster. OSC has been working on compatibility scripts to ensure that the transition goes as smoothly as possible, but users should expect that some things may not work exactly the same.<\/p>\n
In addition,\u00a0there will be some unavailable modules after the migration. Check\u00a0this environment changes page<\/a>\u00a0for more information.<\/p>\n It is highly recommended that\u00a0all OSC users\u00a0test their jobs in the Slurm environment before the migration, in order to avoid any interruption to their production work.\u00a0Before the official Slurm migration on Owens, users can test jobs in Slurm by participating in Owens Slurm Migration Early User Program. No registration is required for the Program, and all OSC users are eligible. All jobs submitted during the Early User Program will not be charged.<\/p>\n Users who submit jobs through the terminal\u00a0can log into Owens in the Slurm environment via SSH to one of the following hostnames:\u00a0owens-slurm.osc.edu<\/a>\u00a0or\u00a0owens-login03.hpc.osc.edu<\/a>. Users can also select ‘>_Owens SLURM Shell Access’ under ‘Clusters’ with the OSC OnDemand tool.<\/p>\n After logging in, users should submit their jobs as they currently do on Owens.\u00a0If it does not work, the workflow will likely fail after the official Slurm migration. Please check OSC’s\u00a0Slurm documentation page<\/a>\u00a0or contact\u00a0OSC Help<\/a>\u00a0for assistance as soon as possible.<\/p>\n Users who use OnDemand apps\u00a0can submit jobs by selecting the ‘Owens SLURM’ option in any of the applicable forms through OnDemand.<\/p>\n Useful information regarding the transition can be found: Slurm migration documentation page<\/a><\/p>\n To stay up to date on system notices, users can follow\u00a0@HPCNotices<\/a>\u00a0on Twitter or visit\u00a0www.osc.edu\/events<\/a>.
