The UMBC High Performance Computing Facility (HPCF)
is the community-based, interdisciplinary core facility for
scientific computing and research on parallel algorithms at UMBC.
The current machine in HPCF is the distributed-memory cluster maya
with over 300~nodes.
The newest components of the cluster are the 72~nodes % in maya (2013)
with two eight-core 2.6~GHz Intel E5-2650v2 Ivy Bridge CPUs and 64~GB memory 
that include 19~hybrid nodes
with two high-end NVIDIA K20 GPUs (graphics processing units)
designed for scientific computing and
19~hybrid nodes with two cutting-edge 60-core Intel Xeon Phi 5110P accelerators.
These new nodes are connected along with the 84~nodes % in maya (2009)
with two quad-core 2.6~GHz Intel Nehalem X5550 CPUs and 24~GB memory 
by a high-speed quad-data rate (QDR) InfiniBand network
for research on parallel algorithms.
The remaining 168~nodes % in maya (2010)
with two quad-core 2.8~GHz Intel Nehalem X5560 CPUs and 24~GB memory
are designed for fastest number crunching and connected by
a dual-data rate (DDR) InfiniBand network. 
All nodes are connected via InfiniBand to a 
central storage of more than 750~TB.
