| ''ssh'' common account text login hosts are **pinnacle.uark.edu**, **trestles.uark.edu**, and **razor.uark.edu**. **trestles** and **razor** login hosts are deprecated and will be shut down as those clusters are integrated into the **pinnacle** Slurm scheduler. Each login host presents the same view of your files but has a different job scheduler and job queue (**pinnacle** Slurm, **trestles** Torque, **razor** Torque). The CSCE cluster has an ''ssh'' login host **karpinski.uark.edu** with separate accounts and files and a Slurm scheduler. The CSCE cluster is also available through [[ https://pinnacle-portal.uark.edu ]]. | ''ssh'' common account text login host is **hpc-portal2.hpc.uark.edu**.
