The KU Community Cluster utilizes the condo model to bring together hardware purchased from different researchers into a single heterogenous cluster. This allows participating researchers to have dedicated use of their purchased nodes, or they may run larger computing jobs by sharing idle nodes owned by other researchers. The main benefit is access to a much larger cluster than would typically be available to a single research group.

The cluster hardware and software is administered by CRC staff. This removes the need for postdocs or graduate students from maintaining your computing system. CRC staff also assists users with any problems they may have using the cluster and helps new users by conducting training sessions and one on one sessions.

Bi-annual purchases will be done for fall and spring semesters dependent on funding. One time purchases can be facilitated, but volume discounts may not be achieved, increasing the price of the hardware.

At this time, you must be an owner of hardware in the KU Community Cluster or be sponsored by an owner group within the cluster to gain access. There is no free partition of the cluster and we currenlty do not have a rate charge of core hours.


CRC offers a Standard Compute Unit (SCU). A SCU is defined as:

  • Dual Intel Xeon 6248 CPU (40 cores @ 2.4GHz
  • 192GB 2933MHz DDR memory
  • with or without EDR Infiniband
  • Gigabit Ethernet 
  • 1TB HDD 7.2K
  • 5 Year NBD Hardware Warranty

On top of the base SCU, we have also offered:

  • SCU w/ 384GB 
  • SCU w/ 768GB
  • SCU w/ SSDs
  • SCU w/ (4) V100 GPUs
  • SCU w/ (2) V100 GPUs

All owner groups will recieve 1TB of $WORK storage for free. Any additional space of $WORK can be purchased for $100 per TB per year. Invoices for storage will be sent 1 year after the storage's start date.

Interested in Purchasing Form

What is your estimated budget for this purchase? This will help CRC estimate amount of servers interested buyers wish to purchase to negotiate bigger discounts through a bigger purchase order.

How many SCUs are you interested in?

Total amount of cores you wish to see in the SCU. CRC tries to propose the best "bang for your buck" CPUs. Leave blank if it does not matter to you. For reference, previous years SCU: (2014 - 20 cores) (2016 - 24 cores) (2018 - 40 cores)
The total amount of memory you require for each server. Leave blank if it does not matter to you. Previous years we offered 128, 256, 512GB of memory. Due to the new Intel CPUs, 3 DIMMS had to be populated with each CPU thus we offered 192, 384, and 768GB of memory in 2018.
If you don't need a total memory amount, but amount of memory per core, enter that here. CRC strives to provide at least 4GB per core.
Is there anything else you wish for CRC to consider when deciding on what type of SCU to propose?
