1 # Facilities, Equipment, and Other Resources
3 ### Computing Facilities
4 The CU Denver Center for Computational Mathematics (CCM) operates a network of clusters, servers, and workstations, which includes:
6 * [Alderaan cluster](../alderaan/), total 2240 AMD EPYC 7502 cores and 4 NVIDIA A-100 GPUs: 2048 AMD 7502 cores and 16TB memory in 32 compute nodes (64 cores and 512GB per node), each with dual 960GB SSDs; 2 high-memory GPU nodes each with two NVIDIA A100 GPU, 2TB memory, and 64 AMD 7502 cores, and 960GB SSDs; head node with 64 cores and 256GB memory; 816TB storage (1PB raw), HDR100 InfiniBand interconnect, and 10Gb/s connectivity from every node to Internet 2. The cluster was funded by the National Science Foundation and installed in 2021.
7 * [Colibri cluster](../colibri/), 384 Intel Sandy Bridge cores, 48 NVidia Tesla M2090 Fermi GPUs, QDR Infiniband interconnect, 104TB disk array, High Memory Interactive Node with 32 cores, and 1TB memory.
8 * [Score cluster](../score/), 100 Intel Ivy Bridge cores, 5 nodes, 192GB memory per node, 10Gbit Ethernet interconnects.
9 * [190TB storage array](../storage/).
10 * Workstations and servers, connected by 1Gbs Ethernet, with 10Gbs uplink to the campus backbone.
12 Accounts are available for faculty and students at CU Denver | Anschutz campuses, as well as to sponsored external collaborars with affiliate appointments. Login is by university credentials.
15 * The clusters use a common SLURM batch scheduler.
16 * Installed software on the clusters network includes MATLAB, R, and GNU compilers. Additional software is installed on request on Alderaan or in Singularity containers for use anywhere.
17 * A large collection of software is available to CU Denver students and faculty through the Office of Information for free or at reduced costs, including a MATLAB site license.
19 ### Personnel Resources
21 * The system administration is done by the CCM Director Jan Mandel, backed by the College of Liberal Arts and Sciences IT, and assisted by student staff.
25 * CU Denver is member of the the [Rocky Mountain Advanced Computing Consortium](https://rmacc.org) (RMACC). The RMACC operates the [Alpine](https://www.colorado.edu/rc/alpine) supercomputer at CU Boulder. Allocations on RMACC resources are available to CU Denver students and faculty. Access to RMACC is through ACCESS federated login (previously XSEDE).
