Non-Allocated Systems
The HPCMP provides a limited number of HPC systems for non-allocated use. These
systems are typically experimental or unique in nature, and do not include a full
complement of application software, however they provide users an opportunity
to explore nontraditional architectures while operating free of the constraints
of allocated use.
Builder is a single-node Aspen Systems Linux Gigabyte server intended primarily to provide a platform for building and sharing Singularity software containers. The system is populated with AMD 7742 processors and Nvidia V100 graphics processing units. Builder uses Intel Gigabit Ethernet as its high-speed network for I/O traffic. Builder uses AVAGO MegaRAID to manage its local file system that targets 130 TB of disk storage. Builder is equipped with two 64-core processors (128 total cores) running the RHEL 8 operating system, two GPUs, 1,024 gigabytes of memory, with no user-accessible swap space.

Reef is an Aspen Systems Linux Cluster. The login and compute nodes are populated with Intel 2.5-Ghz Cascade Lake processors. Reef has 5 CPU-only and 11 GPU compute nodes. Each compute node has two 20-core processors, sharing 768 GBytes of DDR4 memory, with no user accessible swap space. Reef has 109 TBytes (formatted) of disk storage. Reef is intended to be used as a batch scheduled HPC system.
Note: the configuration of Reef is subject to change without notice.
