The creation of HPCF would not have been possible without the support of many individuals and organizations. The following information highlights some details. Thanks to all for the help!

The purchase of the 35-node cluster hpc in 2008 was funded jointly by seed funding provided by UMBC and by funds from the individual researchers Larrabee Strow (Physics), Markos Georganopoulos (Physics), Lynn Sparling (Physics), Maricel Kann (Biological Sciences), Curtis Menyuk (Computer Science and Electrical Engineering), Charles Eggleton (Mechanical Engineering), and Dan Bailey (Imaging Research Center).

The extension of the cluster in 2009 became the replacement purchase of the 86-node cluster tara. We thank the following researchers who added to their earlier contribution or joined the effort: Larrabee Strow (Physics), Wallace McMillan (Physics), Markos Georganopoulos (Physics), Raymond Hoff (Physics and JCET), Charles Eggleton (Mechanical Engineering), Ian Thorpe (Chemistry), Bradford Peercy (Mathematics and Statistics), Do-Hwan Park (Mathematics and Statistics), Weining Kang (Mathematics and Statistics), and Ivan Erill (Biological Sciences).

The purchase of 72 nodes with Intel E5-2650v2 Ivy Bridge CPUs to form the cluster maya extended the QDR InfiniBand interconnect and provided state-of-the-art NVIDIA K20 GPUs designed for scientific computing and cutting-edge Intel Phi 5110P accelerators. This purchase was funded by the 2012 MRI grant as well as significant additional funding from Larrabee Strow (Physics). At the same time, a gift from NASA to UMBC -- the first of its kind -- provided 84 additional nodes very similar to tara, connected by a DDR InfiniBand interconnect. At the same time, UMBC extended the storage dramatically, and maya has a total of more than 750 TB of central storaged connected to it. In total, maya had 240 nodes when released to the public in Summer 2014.

The philosophy of HPCF as a community-based, interdisciplinary core facility was developed in detail in four MRI proposals to the National Science Foundation (NSF).

• The successful proposal submitted in 2012 involved 30 researchers from 10 departments and research centers across the entire campus of UMBC, with PI Matthias Gobbert (Mathematics and Statistics), co-PIs Ivan Erill (Biological Sciences), Marc Olano (Computer Science and Electrical Engineering), Lynn Sparling (Physics), and Ian Thorpe (Chemistry), and co-investigators Tulay Adali (Computer Science and Electrical Engineering), Dan Bailey (Imaging Research Center), Matthew Baker (Geography and Environmental Systems), Marie desJardins (Computer Science and Electrical Engineering), Andrei Draganescu (Mathematics and Statistics), Charles Eggleton (Mechanical Engineering), Erle Ellis (Geography and Environmental Systems), Douglas Frey (Chemical and Biochemical Engineering), Markos Georganopoulos (Physics), Raymond Hoff (Physics and JCET), Maricel Kann (Biological Sciences), Lasse Lindahl (Biological Sciences), Curtis Menyuk (Computer Science and Electrical Engineering), Susan Minkoff (Mathematics and Statistics), Tinoosh Mohsenin (Computer Science and Electrical Engineering), Nagaraj Neerchal (Mathematics and Statistics), Tim Oates (Computer Science and Electrical Engineering), Kevin Omland (Biological Sciences), Bradford Peercy (Mathematics and Statistics), Penny Rheingans (Computer Science and Electrical Engineering), Stuart Schwartz (CUERE), Larrabee Strow (Physics), Claire Welty (Civil and Environmental Engineering and CUERE), Zhibo Zhang (Physics), John Zweck (Mathematics and Statistics).
• The proposal submitted in 2011 involved 41 researchers from 15 departments and research centers across the entire campus of UMBC, with PI Matthias Gobbert (Mathematics and Statistics), co-PIs Ivan Erill (Biological Sciences), Marc Olano (Computer Science and Electrical Engineering), Lynn Sparling (Physics), and Ian Thorpe (Chemistry), and co-investigators Tulay Adali (Computer Science and Electrical Engineering), Dan Bailey (Imaging Research Center), Matthew Baker (Geography and Environmental Systems), Jonathan Bell (Mathematics and Statistics), Marie desJardins (Computer Science and Electrical Engineering), Andrei Draganescu (Mathematics and Statistics), Charles Eggleton (Mechanical Engineering), Erle Ellis (Geography and Environmental Systems), Scott Farrow (Economics), Timothy Finin (Computer Science and Electrical Engineering), Douglas Frey (Chemical and Biochemical Engineering), Chris Geddes (Institute of Fluorescence), Markos Georganopoulos (Physics), Raymond Hoff (Physics and JCET), Maricel Kann (Biological Sciences), Gunes Koru (Information Systems), James Lo (Mathematics and Statistics), Wayne Lutters (Information Systems), Ronghui Ma (Mechanical Engineering), Curtis Menyuk (Computer Science and Electrical Engineering), Susan Minkoff (Mathematics and Statistics), Tinoosh Mohsenin (Computer Science and Electrical Engineering), Nagaraj Neerchal (Mathematics and Statistics), Charles Nicholas (Computer Science and Electrical Engineering), Tim Oates (Computer Science and Electrical Engineering), Kevin Omland (Biological Sciences), Bradford Peercy (Mathematics and Statistics), Roy Rada (Information Systems), Muruhan Rathinam (Mathematics and Statistics), Penny Rheingans (Computer Science and Electrical Engineering), Stuart Schwartz (CUERE), Larrabee Strow (Physics), Haijun Su (Mechanical Engineering), Claire Welty (Civil and Environmental Engineering and CUERE), Liang Zhu (Mechanical Engineering), John Zweck (Mathematics and Statistics).
• The proposal in 2008 involved 23 researchers from 10 departments and research centers from all three colleges at UMBC, with PI Matthias K. Gobbert (Mathematics and Statistics), co-PIs Lynn Sparling (Physics), Marie desJardins (Computer Science and Electrical Engineering), Penny Rheingans (Computer Science and Electrical Engineering), and Marc Olano (Computer Science and Electrical Engineering), and co-investigators Florian A. Potra (Mathematics and Statistics), Andrei Draganescu (Mathematics and Statistics), John Zweck (Mathematics and Statistics), Nagaraj K. Neerchal (Mathematics and Statistics), Wallace McMillan (Physics), Markos Georganopoulos (Physics), Larrabee Strow (Physics), Stephen J. Freeland (Biological Sciences), Maricel G. Kann (Biological Sciences), Curtis R. Menyuk (Computer Science and Electrical Engineering), Charles D. Eggleton (Mechanical Engineering), Claire Welty (Civil and Environmental Engineering and CUERE), Erle C. Ellis (Geography and Environmental Systems), Jeffrey B. Halverson (Geography and Environmental Systems and JCET), Scott Farrow (Economics), Andrew Tangborn (JCET), Erricos C. Pavlis (JCET), and Stuart S. Schwartz (CUERE).
• Some additional faculty involved in the 2007 MRI proposal also helped shape the vision, who were Susan K. Gregurick (Chemistry), Daniele Fabris (Chemistry), Jacob Kogan (Mathematics and Statistics), Howard E. Motteler (Physics), Charles Nicholas (Computer Science and Electrical Engineering), and Philip J. Rous (Physics).
