Investment criteria and standard node configurations are reviewed annually at the beginning of each fiscal year by OIT. This page has been updated for FY22.
If you are working on a proposal and need the ISAAC facilities document it is available here (UT authentication required).
Faculty and other University researchers may purchase compute nodes to be placed in the ISAAC HPC cluster using sponsored research funds, startup funds, or other funds for a private condo. These private condo nodes are exclusive to investors, their project(s), and project members. In addition to private condo exclusive use (the default) private condo resources can participate in the responsible node sharing program. If you wish to investigate purchasing nodes or know what you want and are ready to purchase nodes for use in a private condo the cluster, please submit an HPSC Service Request (ticket) at this link. A staff member will contact you to discuss details regarding the purchase and once you want to commit to a purchase you will work with the Associate CIO for Service Level and Capacity Management to develop a service level agreement (SLA) that will apply for the equipment purchase (equipment, cost, service period, etc.). For FY22, the standard SLA period for a compute or GPU node investment will be three years. Other periods will be considered on a case-by-case basis including a proposal or award performance period.
Note that costs below are estimates and final costs will be determined based on equipment configuration usually in the form of a vendor quote or an OIT Service Level Agreement document corresponding to the funding source. Federal research R accounts can only be charged the direct equipment cost since our facility is not a cost center. A vendor quote would be provided for inclusion in a proposal. After an award, the vendor quote would be requested again as usually vendor quotes are only good for 30 days.
Intel, AMD, and Dell have come out with new generation technology for FY22 that Dell calls their 15th generation technology based on Intel Xeon Ice Lake processors and AMD Milan processors. For a period of time we will be able to get 14th generation Dell technology, but at some point in time it will no longer be available and Dell will no longer provide quotes for previous generation technology. We already know we will no longer be able to order AMD Rome processor based technology. The compute node costs below are an estimated one-time costs for the three year period.
Note all prices below are estimates, pricing change approximately monthly, and Dell advised us in July 2021 that due to the industry-wide shortage of chips, glass, and other parts, memory prices and lead times are increasing.
While 14th generation compute node technology is still available, below specifices a powerful compute node that can handle significant HPC workloads. The pertinent technical specifications are listed below.
The estimated cost for a this 14th generation standard compute node is now just over $10,000. Modifications can be made to the above configuration on a case-by-case basis while available.
With the 15th generation standard compute node, investors will obtain a powerful compute node based on Intel Xeon Ice Lake processors or AMD Milan processors that can handle significant HPC workloads. The pertinent technical specifications are listed below.
Intel Ice Lake based compute node:
The estimated cost for a standard Intel processor compute node is approximately $12,700. Modifications can be made to the above configuration on a case-by-case basis.
Information for a Dell PowerEdge R6525 with AMD Milan processors will be available soon.
With the standard 14th generation GPU node while still available, investors will obtain a compute node that can handle standard HPC workloads and has significant GPU performance for GPU-intensive applications. The pertinent technical specifications are listed below.
The estimated cost for a single standard GPU node is approximately $24,500 depending on the type and quantity of GPUs. Modifications can be made to this configuration on a case-by-case basis.
With the standard GPU node, investors will obtain a compute node that can handle standard HPC workloads and has significant GPU performance for GPU-intensive applications. The pertinent technical specifications are listed below.
As of August 10, 2021 Dell informed us the NVIDIA V100S GPU is not available in the 15th Generation. Will obtain sample quotes for Ampere GPUs of which now there is an entire product line (A100, A40, A30, A10 and also T4). The estimated cost for a 15th generation GPU node with two T4 GPUs is $15,020 and with two A100 GPUs is ~$28,000. Modifications can be made to this configuration on a case-by-case basis.
Information for a Dell PowerEdge R7525 with AMD Milan processors and either T4 or A100 GPUs will be available soon.
Unpurged Lustre project storage space (/lustre/haven/proj/…) is available as well as purged Lustre scratch space (/lustre/haven/user/…). Project storage spaces have quotas enabled and Lustre scratch does not empose quotas. University of Tennessee projects receive 1 terabyte (TB) of Lustre project space for no additional cost to the research project. Any project storage beyond 1TB for University of Tennessee sponsored projects and other funded projects should be purchased. External organizations and University faculty leading sponsored projects or other funded projects can purchase storage resources on the high-performance Lustre storage system for their research projects. The FY21 cost per terabyte was $59 and the FY22 cost per terabyte is being calculated and will be available soon. Also, Lustre file systems have a finite number of files that the entire file system can contain. Any project or researcher that uses more that 10 million files will also be charged $100 per year for every 1 million files over the first 10 million.
Please note that the previously listed storage costs only includes the storage equipment, administration, and maintenance of the file system and does not include backups. Backups of Lustre storage are the responsibility of the end users. On a case-by-case basis arrangements can be made for limited amounts of some type of backups, such as, as a duplicate copy or snapshot and should be discussed and included into any investment Service Level Agreement. For more information on the available file systems, please refer to the File Systems document.
