Mason, Indiana University's large memory computer cluster, will be retired on January 1, 2018.

Carbonate ( is Mason's replacement and is currently available to IU students, faculty, and staff. To request an account on Carbonate, follow the instructions in Get additional IU computing accounts.

Carbonate nodes run RHEL7. To coordinate resource management and job scheduling, they use the Torque resource manager integrated with Moab Workload Manager. To customize shell environments, they use the Modules environment package. For more, see About Carbonate at Indiana University and Get started on Carbonate.

System detail comparison

Carbonate consists of 72 compute (256 GB) nodes and eight large memory compute nodes (512 GB); each node is a Lenovo NeXtScale nx360 M5 server, containing dual Intel Xeon 2680 v3 processors, 10 GB Ethernet adapters, and four 480 GB solid-state drives. Carbonate fully supports high-performance, data-intensive computing, and provides nearly an eighteenfold increase in processing capability over Mason. For more details on Carbonate's system configuration, see About Carbonate at Indiana University.
