Talon 3 Launches

Slurm, the workload manager for UNT's High Performance Computing StudioPhoto of the backside of Talon 3April 17, 2017 – Talon 3's launch began in earnest April 5, 2017, with a workshop to unveil a new batch-queuing system and user-support portal. A small group has been beta testing the new cluster, said DaMiri Young, manager, High-Performance Computing.

The HPC team has implemented a new job-control system for Talon 3 called Slurm, an open source, fault-tolerant, and highly scalable cluster management and job-scheduling system for large and small Linux clusters.

"It is advisable to begin familiarizing yourself if you haven't already. Unfortunately, currently-running jobs and job scripts are not compatible with the new system. The plan is to close the UGE queues on Talon 2 next week and let those jobs in execution run to completion. You will need to rewrite/resubmit your job to the SLURM system unless you utilize the run script," Young said.

It has 14 cores in each of the Intel Xeon E5-2680 CPUs in the 208 new Dell servers.
It has 355 servers in 13 racks that include the 208 Dell new servers and 147 Talon 2 servers that will be redeployed in Talon 3.
