Supercomputers for academic research at IU

On this page:


At the heart of Indiana University's cyberinfrastructure are the robust, reliable supercomputing systems provided and managed by the Research Technologies division of UITS. These world-class research supercomputers, and the proven professional training, consultation, and support services Research Technologies provides, enable computing research experimentation and implementation, and amplify the talents of local and national researchers. Specific information about each IU research supercomputer is provided below.

Big Red 200

Big Red 200 is a Cray Shasta supercomputer designed to support scientific and medical research, and advanced research in artificial intelligence, machine learning, and data analytics. Installed at Indiana University in January 2020, Big Red 200 is expected to enter production service during the fall 2020 semester.

For more, see About Big Red 200 at IU.

Big Red 3

Big Red 3 is a Cray XC40 supercomputer dedicated to researchers, scholars, and artists with large-scale, compute-intensive applications that can take advantage of the system's extreme processing capability and high-bandwidth network topology. Big Red 3 supports programs at the highest level of the university, including the Grand Challenges program.

Carbonate is Indiana University's large-memory computer cluster. Designed to support high-performance, data-intensive computing, Carbonate is particularly well-suited for running genome assembly software, large-scale phylogenetic software, and other genome analysis applications that require large amounts of computer memory. To support researchers with deep learning applications, Carbonate also is equipped with 12 GPU-accelerated deep learning (DL) nodes. Additionally, Carbonate provides a "condominium cluster" environment for IU researchers, research labs, departments, and schools.

Carbonate deep learning nodes

To facilitate the support of deep learning applications and research, Indiana University's Carbonate cluster has been expanded to include 12 GPU-accelerated Lenovo ThinkSystem SD530 compute nodes. Each of these deep learning (DL) nodes is equipped with two Intel Xeon Gold 6126 12-core CPUs, two NVIDIA GPU accelerators (eight with Tesla P100s; four with Tesla V100s), four 1.92 TB solid-state drives, and 192 GB of RAM. All DL nodes are housed in the IU Bloomington Data Center, run Red Hat Enterprise 7.x, and are connected to the IU Science DMZ via 10-gigabit Ethernet.
