Established in 1983, the Minnesota Supercomputing Institute (MSI) is the University of Minnesota's principle center for computational research. MSI provides services to over 850 active groups that sponsor more than 4,500 unique users from 19 different university colleges, maintaining an array of systems dedicated to the computational needs of investigators in the state of Minnesota's higher education institutions and their collaborators.
High Performance Computing
MSI's High Performance Computing (HPC) systems are designed with high speed networks, high performance storage, GPUs, and large amounts of memory in order to support some of the most compute and memory intensive programs developed today. MSI currently has two main HPC systems, Itasca and Mesabi. Taken together, these systems are comprised of 26,560 X86 64-bit compute cores and 92 TB of RAM, which can support over 800 TFLOPS of peak performance. The majority of MSI's HPC compute nodes are equipped with at least 64 GB of RAM. A subset of nodes are equipped with either 256 GB or 1 TB of RAM in order to support applications that require a large amount of memory, 32 nodes have Solid State Drives (SSDs) to support applications with demanding input and output (I/O) requirements, and 40 nodes include two NVidia Tesla K20X general purpose GPU accelerators.
Interactive Computing and Scientific Visualization
In collaboration with the Laboratory of Computational Science and Engineering, the MSI supports an immersive visualization laboratory with active 3D stereographic and motion tracking systems. The Lab can accommodate up to 24 people and is located in the same building as the MSI. MSI also supports specialized interfaces (i.e., NICE EnginFram and Citrix) and hardware for remote visualization and interactive computing. Interactive HPC systems allow real-time user inputs in order to facilitate code development, real-time data exploration, and visualizations. Interactive HPC systems are used when data are too large to download to a desktop or laptop, software is difficult or impossible to install on a personal machine, or specialized hardware resources (e.g.., GPUs) are needed to visualize large data sets.
MSI supports a cloud computing platform built on OpenStack to allow quick deployment of web, database, and other non-High Performance Computing systems. The virtual instances in this environment are a variety of sizes depending on the number of processors and the amount of memory and disk space required for the project.
All MSI researchers have access to a high-performance parallel storage platform. This system provides 2.4 PB (PetaBytes) of storage with sustained read and write speeds of up to 25 GB/sec. The integrity of the data is protected by daily snapshots and tape backups. High value data sets are backed up to an off site facility as a part of the institute's disaster recovery plan. MSI also supports a second tier storage solution designed to address the growing need for resources that support data-intensive research. The system is tightly integrated with other MSI storage and computing resources in order to support a wide variety of research data life cycles and data analysis workflows and uses Amazon's S3 (Simple Storage Service) interface, so that researchers can better manage their data, more seamlessly share data with other researchers, and migrate entire data analysis pipelines to cloud-based platforms.
Data Centers, Network Connectivity, and Office Facilities
MSI enables interdisciplinary research through its robust data center facilities with over 1 MW of IT capacity to support leading edge computational and data storage systems. MSI supports two data centers, both of which are connected to the 10 Gbps campus network and the 100 Gbps dedicated science network called the Gopher Science Network (GSN). Dedicated 10 and 100 Gbps links to our regional optical network and Internet2 give our researchers the network capacity and capability needed to collaborate with researchers from around the world. Located in the Walter Library building, MSI office and data center space (~ 18,000 sq. ft) are centrally located on the Minneapolis campus. MSI also maintains office spaces on the Saint Paul campus where additional researchers are located. MSI also provides computer and teaching laboratories that are routinely used for research by users but also for outreach and teaching workshops.
