Familiarity with a parallel storage system (GPFS, Lustre, BeeGFS, etc.) is highly desired. Similar familiarity with on-premise and cloud-based virtual machine environments (VMWare, AWS, OpenStack, Azure, etc.) is also highly desirable. The candidate must be able to meet with members of the research community, gather requirements, and suggest possible solutions and/or assist in using CIRC resources. The ability to evaluate new storage architectures, systems, and software tools to determine the best techniques for achieving performance and to identify future acquisition objectives is required. The successful candidate must be able to respond to emergency situations involving system troubleshooting, debugging, and monitoring triggers. Creating and maintaining documentation aligned with CIRC’s workflow tracking is also critical. Candidates must be able to work in a team environment and be able to adapt and deploy new technologies, as appropriate.
The Center for Integrated Research Computing supports the University of Rochester’s research mission by providing technical computing services to the institution’s research community. These services include high performance computing, visualization, large, fast, reliable storage systems and hundreds of software packages used by researchers to analyze data. CIRC also provides assistance with using these tools via workshops, classes, tutorials and consulting services. This position is important due to the indirect and direct support provided to the researchers in achieving and maintaining a high level of satisfaction by the research community.

Center for Integrated Research Computing (CIRC)
The University of Rochester established the Center for Integrated Research Computing (CIRC), focused on the themes of computation and analytics, to provide researchers across the Medical Center and River Campus with resources necessary to utilize high-performance computing (HPC) and data analytics technology in all areas of academic scholarship. CIRC currently maintains systems with an aggregated computational performance of approximately 630 TFLOPS, 4.5 PB of disk storage, and a variety of scientific software applications and tools, supporting over 60 departments and research centers. Resources that ensure access to the technology and knowledge for effective computational and analytics research include: computer systems, software, storage, experienced staff, student assistants, information sharing, collaboration tools, and an education and training program. From novice users, unfamiliar with the command line environment of a Linux cluster, to research associates who have compilation and optimization questions about custom-developed software, CIRC is uniquely positioned to collaborate with faculty and students in computational research design and realization, software implementation and lifecycle management, application porting and tuning, data visualization and analysis techniques, and development of new computational technologies, methods and instructional resources.How To Apply
