The Georgia Cancer Center's Bioinformatics Shared Resource provides expertise in integrative computational-based analysis solutions to basic, clinical, and translational research applications.
Bioinformatics support ranges in scope from simple consultations to more in-depth collaborations. We require the participation of the investigator during the course of our data analysis because we believe that input into the biological parameters are tantamount to success of the analysis.
Campus users have access to several advanced computing servers owned by the Georgia Cancer Center, including a High Performance Computing Server (HPC) that has 544 total compute cores and an aggregated memory of 2.9TB. The system is composed of 15 PowerEdge R430 1U systems (128 GB RAM each node), 1 PowerEdge R830 (high memory 1024 GB RAM node), and a high-speed 40GbE interconnect for intraserver communication. The HPC also houses 652 TB RAW storage capacity known as Qumulo, allowing the functionalities of effective management and maintenance as well as highly efficient analysis of large data sets, and is committed to the Bioinformatics Shared Resource. Training or a knowledge of Linux is required to use the HPC server.
Booking of server time is done through ilab. iLab allows researchers, PIs, financial managers, and core managers to ensure that they are using valid payment information (Chart Field Combination or CFC) at each step of the request and billing process for core facilities. Financial managers assign CFCs to lab members who will order services from AU cores. Researchers can order services with valid CFC, and core managers can bill for these services knowing that they are using valid CFCs.
