Roar System Layout
Roar is a heterogeneous cluster that consists of multiple node-types connected to a common file system. The primary portions are ACI-b, the batch portion of the cluster; ACI-i, the interactive portion; and the data-manager nodes.
Compute resources are available in four configurations: Basic Memory, Standard Memory, High Memory, and GPU.
| Node Types | Specifications |
|---|---|
| Basic | 2.2 GHz Intel Xeon Processor, 24 CPU/server, 128 GB RAM, 40 Gbps Ethernet |
| Standard | 2.8 GHz Intel Xeon Processor, 20 CPU/server, 256 GB RAM, FDR Infiniband, 40 Gbps Ethernet |
| High | 2.2 GHz Intel Xeon Processor, 40 CPU/server, 1 TB RAM, FDR Infiniband, 10 Gbps Ethernet |
| GPU | 2.5 GHz Intel Xeon Processor, 2 Nvidia Tesla K80 computing modules/server, 24 CPU/server, Double Precision, FDR Infiniband, 10 Gbps Ethernet |
The Roar system uses the Red Hat 7.9 Linux operating system with the module system set up for software. All users will have to use the terminal to access programs, including Open OnDemand users of ACI-i.
