ACM Tech Talk Series

​A Practitioner’s Introduction to Deep Learning

​Ashwin Kumar Ganesan, PhD student

1:00-2:00pm Friday, 17 November 2017​, ITE325, UMBC

In recent years, Deep Neural Networks have been highly successful at performing a number of tasks in computer vision, natural language processing and artificial intelligence in general. The remarkable performance gains have led to universities and industries investing heavily in this space. This investment creates a thriving open source ecosystem of tools & libraries that aid the design of new architectures, algorithm research as well as data collection.

This talk (and hands-on session) introduce people to some of the basics of machine learning, neural networks and discusses some of the popular neural network architectures. We take a dive into one of the popular libraries, Tensorflow, and an associated abstraction library Keras.

To participate in the hands-on aspects of the workshop, bring a laptop computer with Python installed and install the following libraries using pip.  For windows or (any other OS) consider doing an installation of anaconda that has all the necessary libraries.

• numpy, scipy & scikit-learn

Volunteer to help in UMBC’s Hour of Code events, Dec 4 and 5

Hour of Code is a worldwide effort to celebrate computer science using a one-hour coding activity. The one hour coding activity is designed to show that anyone can learn the basics of coding, and to create a more inclusive computer science community. The CS Education student organization, with support from the CS Matters in Maryland CS education project, will host UMBC’s Hour of Code event on Monday (Dec. 4) and Tuesday (Dec. 5).

On December 4th from 10am-1pm, they will host the Hour of Code event for anyone who wants to try the coding activities on Main Street.

On December 5th from 11am-2pm, they will have special guests. Some students from Lakeland Elementary School will learn to code along with President Freeman Hrabowski.

The CS Education Club needs volunteers to make this event a success. Coding experience is useful, but not necessary. They will host training sessions prior to the event for everyone who volunteers. The training will give you a chance to try our Hour of Code activity along with a Makey Makey activity.  Read about last year’s Hour of Code event at UMBC here.

UMBC upgrades High Performance Computing Facility through new NSF grant, expanding possibilities for data-intensive research

The National Science Foundation recently awarded UMBC a Major Research Instrumentation (MRI) award totaling more than $550,000 to expand the university’s High Performance Computing Facility (HPCF). The funding will go toward upgraded hardware and increased computing speeds for the interdisciplinary core facility, which supports scientific computing and other complex, data-intensive research across disciplines, university-wide. As part of the NSF grant, UMBC is required to contribute 30 percent of the amount that NSF is providing to further support the project, meaning a total new investment of more than $780,000 in UMBC’s High Performance Community Facility.

Meilin Yu, assistant professor of mechanical engineering, is the principal investigator on the grant. He replaced Matthias Gobbert, professor of mathematics, who served as principal investigator on previous grants for the core facility in 2008, 2012 and 2017 on behalf of the 51 faculty investigators from academic departments and research centers across all three colleges. Co-Principal investigators on the grant are Professors Marc Olano, Jianwu Wang and Daniel Lobo.

“The MRI grant will allow us to upgrade the UMBC HPCF with state-of-the-art computing nodes and networks,” explains Yu. “It will boost sustained growth in research and education relating to computational science and engineering, including but not limited to, high performance computing, cybersecurity and big data, atmospheric physics, environmental science and engineering, and life sciences.”

Through the facility, researchers can run simulations with a range of applications, including industrial designs and weather prediction. UMBC faculty will utilize the upgraded system to complete simulations and modeling tasks significantly faster than the current system allows, explain Yu and Gobbert. The updated technology includes accelerated graphics processing units that, in addition to speeding up calculations, will “improve the quality of digital visualization,” says Yu.

The HPCF governance committee is working with UMBC’s Division of Information Technology to purchase and implement the upgraded hardware, including central processing units, which completes computing tasks, graphics processing units, which manages the visual displays on computers, and cores. “We hope to have at least 72 nodes in service to the UMBC community by spring 2018, with 16 core Central Processing Units, Graphics Processing Units suitable for integer/single-precision and double-precision arithmetic, and cutting-edge many-core Intel Xeon Phi KNL processors with 68 cores,” Gobbert explains, adding that by increasing the number of nodes, UMBC’s HPCF is worth more than $2 million.

UMBC faculty are able to use the facility for their research at no charge, and they receive technical support from graduate assistants as well as staff in UMBC’s Division of Information Technology. The upgraded facility will support projects from researchers in more than a dozen academic departments across all three colleges at UMBC. Gobbert shares that he expects this community of scholars will expand further as the core facility continues to grow. “I am most proud of the fact that such a large number of faculty total put their trust in me to lead the writing and management of this proposal,” he said. “Our success at the NSF validates that the strong interdisciplinary cooperation of many researchers from across the campus is valued there.”

The HPCF was established in 2008 in response to a university-wide need for technology to support high-performance computing. The initial system had 35 nodes, and was funded by UMBC’s Division of Information Technology, the Office of the Vice President for Research and faculty contributions. Over the past nine years, the HCPF has grown to include over 300 nodes, and has been used by more than 400 researchers and students for their work. The facility has led to more than 250 publications, including 100 in peer-reviewed journals, in addition to 30 theses. The recent funding will support the expansion of the facility to include 84 nodes, which individually communicate with each other, and cutting-edge processors. The oldest portion of the HPCF will be replaced with with more powerful nodes.

CHMPR Distinguished Lecture Series

Energy Exascale Earth System Model

Dr. Mark Taylor, E3SM Chief Computational Scientist, Sandia National Laboratories

2:30pm Tuesday, 31 October 2017, ITE 325, UMBC

Dr. Taylor will present an overview of the DOE Energy Exascale Earth System Model (E3SM), including Sandia’s role in numerical algorithms, parallel scalability, and computational performance. E3SM is designed to run on upcoming next-generation DOE supercomputers. Adapting simulation codes to these new architectures is expected to be more disruptive than the previous transition from vector to massively parallel supercomputers. E3SM development is driven by several grand challenge science questions focused Earth’s cryosphere, biogeochemical and water cycle systems. E3SM has a new land and atmosphere component models branched from the CESM v1.2, coupled to new MPAS ocean, sea ice, and land ice models.

The current performance and throughput challenges of the E3SM high-resolution coupled configuration on several DOE computers will be discussed. Our current focus is on the NERSC Cori system with Intel Xeon Phi architecture, in the longer term we hope to make effective use of the upcoming NVIDIA GPU based system at ORNL. An analysis is presented of the E3SM spectral element atmosphere dycore following the NGGPS dycore computational evaluation protocol, but with an emphasis on the throughput rates needed for climate simulations. For even higher resolution simulations, we will rely on E3SM’s ability to use unstructured grids in all component models. This will allow us to achieve cloud-resolving resolution in select regions of interest seamlessly within the global modeling system.

Mark Taylor is a mathematician who specializes in numerical methods for parallel computing and geophysical flows. He currently serves as Chief Computational Scientist for the DOE’s Accelerated Climate Modeling for Energy (ACME) project. Mark developed the mimetic/conservative formulation of the spectral element method, one of the atmospheric dynamical cores used in the Community Earth System Model (CESM) and the ACME project. Mark received his Ph.D. from New York University’s Courant Institute of Mathematical Sciences in 1992 and has worked at Sandia National Laboratories since 2004. In 2014 he was awarded The Secretary of Energy Achievement Award for his work unifying the DOE climate modeling research community and enabling the development of high-resolution fully-coupled climate-system simulations.
