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.
