Condominium model

Palmetto cluster operates in a condominium model which allows faculty to invest in the cluster. Investments into Palmetto are based on purchases of compute nodes. By purchasing a compute node faculty get priority to use an equivalent hardware across whole Palmetto cluster. All not used compute cycles are made available for general Clemson users. Owners may preempt other users making the hardware they purchased immediately available. Purchased nodes are available to faculty for a period of 4 years, after that the priority to use them expires.

Being an owner allows users to

  • have immediate access to the amount they have purchased by preempting other users
  • have a dedicated group on Palmetto cluster
  • invite external collaborators (not associated with Clemson) to use their purchased resources
  • have extended maximum time for a single task up to 336 hours (14 days)

For more information about condominium model and purchasing Palmetto nodes, including Palmetto nodes on grants please contact Jeronica Williams or Marcin Ziolkowski

Temporary storage

Palmetto includes several file systems designed for storing temporary files

  1. Local disk on compute nodes
  2. Following global scratch systems
File system Directory Capacity Features
OrangeFS /scratch1 233 TB - distributed file system based on OrangeFS
- available to all compute nodes and the login node
- no quota per user
- files not accessed for 30 days deleted on first day of each month
- designed for parallel I/O
ZFS /scratch2 150 TB - single server sharing space to all compute nodes and the login node
- no quota per user
- files not accessed for 30 days deleted daily
- designed for general I/O patterns (small and/or single process I/O)
XFS /scratch3 129 TB - single server sharing space to all compute nodes and the login node
- no quota per user
- files not accessed for 30 days deleted daily
- designed for general I/O patterns (small and/or single process I/O)

Long term storage

Long term storage solutions are available to users seeking a dedicated high performance storage. This service is provided for fee to Clemson users. Palmetto users may purchase ZFS storage with either dedicated server (purchasing of 150TB) or shared server (purchase in 1TB increments).

Long term storage space includes snapshots of changes and mirror system for disaster recovery.

Cypress Cluster

Clemson cyberinfrastructure includes a dedicated Hadoop environment, called Cypress, that is integrated with Palmetto’s infrastructure. The Cypress Cluster uses the Hortonworks Data Platform distribution of Hadoop and Spark to support data intensive computing and analytics. Cypress is available to all students, faculty, and staff with Palmetto Cluster accounts.


  • available for free to all Clemson students, faculty, and staff
  • 3.64 PB (petabyte) global Hadoop Distributed File System (HDFS)
  • 40 worker nodes (responsible for computation and data storage)
    • 256 GB of RAM per node
    • 16 nodes each have 12 1-TB local disks
    • 24 nodes each have 24 6-TB local disks
  • one dedicated Cypress Cluster user node for job submission and data staging
  • Hortonworks Data Platform distribution of Hadoop, Spark, and other Hadoop ecosystem services

For more information about investing into Cypress Cluster please contact Jeronica Williams or Linh Ngo

More about Cypress


The Cypress Cluster and data related support are provided by the Data Science group:

Open Science Grid

Open Science Grid (OSG) is a freely accessible distributed computing resource for scientific calculations designed to handle huge number of “small” computational tasks - high throughput computing (HTC).

Clemson University has been working with OSG on providing seamless access to the OSG resources for Clemson researchers. OSG has been recently integrated into the Palmetto cluster for sending and receiving high throughput jobs using the OSG framework. Access to OSG is free of charge.

Access to OSG from Palmetto is available using Connect Client software. OSG uses separate accounting system and before trying it Clemson users need to request an OSG account.
