The UMBC High Performance Computing Facility (HPCF)
is the community-based, interdisciplinary core facility for
scientific computing and research on parallel algorithms at UMBC.
Started in 2008 by more than 20 researchers from
ten academic departments and research centers
from all academic colleges at UMBC, it is supported by
faculty contributions, federal grants, and the UMBC administration.
Since HPCF's inception, over 400
users have benefited from its computing clusters,
including undergraduate and graduate students.
The users generated over 400~publications,
including 150~papers in peer-reviewed journals
(including Nature, Science, and other top-tier journals 
in their fields), 50~refereed conference papers, and 50~theses.
The facility is open to UMBC researchers at no charge.
Researchers can contribute funding for long-term priority access.
System administration is provided by the
UMBC Division of Information Technology,
and users have access to consulting support provided by
dedicated full-time graduate assistants.

HPCF currently consists of two machines, taki and ada,
and both are comprised of several types of nodes.
The CPU cluster consists of
18~compute nodes with two 24-core Intel Cascade Lake CPUs
and 196 GB of memory each and
50~compute nodes with two 18-core Intel Skylake CPUs
and 384~GB of memory each.
This cluster also includes 4~nodes in a develop partition
and one interactive node.
The taki GPU cluster contains
one node with four NVIDIA Tesla V100 GPUs connected by NVLink.
The ada GPU cluster is comprised of
13~nodes which each have two 24-core Intel Cascade Lake CPUs
and 384~GB of memory.
Four of these nodes have eight 2080~Ti~GPUs;
seven of these nodes have eight RTX~6000~GPUs; and
two of these nodes have eight RTX~8000~GPUs
with an extra 384~GB of memory each.
The nodes are connected to each other by
EDR (extended data rate) InfiniBand interconnect.
All nodes of both machines are connected to the
same central storage of more than 750 TB.
