Proposal Writing Information
Georgia Advanced Computing Resource Center Useful Information for Proposal-writing
The text below is intended to provide most of the information your proposal will need, if it includes reference to the GACRC for support of HPC resources or consulting in the use of HPC resources for your proposed research. We do not envision that each proposal will need all information. Please contact GACRC staff (firstname.lastname@example.org) for assistance in crafting language for your specific proposal, if required.
If your grant proposal includes the use of computing resources to be under the stewardship of the GACRC, whether you intend to purchase new hardware or software or use what is already available to you, the GACRC can assist you in the following ways (given adequate lead time):
- Writing cost justifications and Management Plan(s) for IT resources
- Preparing an IT budget
- Soliciting budget proposals from prospective hardware, software and/or service providers
- Conducting final negotiations with IT hardware, software and/or service providers before procurement
Brief GACRC Overview (Typical Grant Proposal Text)
The Georgia Advanced Computing Resource Center's (GACRC) equipment is located in UGA's Boyd Data Center (BDC). The GACRC has a fulltime staff of Systems Administrators and Scientific Computing Consultants, specializing in Linux/UNIX system administration, storage administration, and scientific computing consultation. One Linux cluster is available with a total core count of approximately 32,800 compute-cores. In addition to conventional compute nodes, the cluster has several large memory and GPU specific nodes. High-performance storage for the Linux clusters is provided for users' home directories and temporary scratch space. Slower storage resources are available for long-term project needs. The home directories, as well as the long-term project storage are backed-up to separate storage devices.
The computational and storage resources are available free of charge to UGA researchers and students. A Faculty Buy-In program is also in place which provides prioritized access to the GACRC-administered computational resources.
The GACRC regularly hosts training sessions on a number of subjects relevant to the use of its computational and storage resources. Prospective UGA users are required to attend an introductory session before being granted access to any of the GACRC compute resources.
The GACRC manages over 900 software packages, utilities, compilers and libraries. Of these over 650 are bioinformatics related.
Additional Details (As Needed)
Major Equipment: The computational resources at the GACRC encompasses a Linux cluster as well as a multi-tiered storage environment that serves it.
The GACRC's current research-dedicated Linux cluster, called Sapelo2, presents the following resources, purchased over a number of years since 2014. Included in this list are over 200 compute nodes in various configurations, purchased through the GACRC’s Faculty Buy-In program. The overall core count of the cluster as it stands in October 2022 is 32,812 with a total memory footprint of 147.8TB.
The following tables present a detailed overview of the various compute node configurations present on Sapelo2.
Two inter-nodal InfiniBand fabrics coexist within the Sapelo2 cluster. The older is a QDR InfiniBand fabric arranged in a 2:1 fat tree configuration. Switches are 2x Intel TrueScale 12800-120 and 14x Intel TrueScale 12300. The newer fabric is based on Mellanox EDR SB7800/SB7890 switches, also arranged in a 2:1 fat tree configuration.
