Emerging Challenges in High Performance Computing: Resilience and the Science of Embracing Failure

John. T. Daly
Advanced Computing Systems Program at the Department of Defense / Center for Exceptional Computing

1:00 p.m. Friday, 9 November 2012, ITE 227, UMBC

Resilience is about keeping the application workload running to a correct solution in a timely and efficient manner in spite of system failures. Future extreme scale supercomputers are likely to suffer more frequent failures than current systems: As devices scale, they are more susceptible to upsets due to radiation and to errors due to manufacturing variances. The probability of multiple bit upsets is growing, since an event is increasingly likely to impact multiple nearby cells. The use of near-threshold voltage in order to reduce power consumption also increases error rates. Thus, we can expect more frequent hardware failures, and a significant rate of undetected soft errors. While it is desirable to have failure-free system hardware and software, this goal may not be achievable at reasonable cost as both hardened components and methodologies to design and test critical software tend to be extremely expensive. The challenge is to construct a system out of less than perfectly reliable hardware and software that nevertheless behaves as a reliable system from the perspective of the user.

John T. Daly is a computer systems researcher for the Advanced Computing Systems (ACS) Program at the Department of Defense / Center for Exceptional Computing (CEC). He is focused on the problem of keeping supercomputer applications running toward a correct solution in a timely and efficient manner in the presence of system degradations and failures. His research interests include mathematical modeling and analysis of failure, reliability, fault tolerance, calculational correctness, and throughput for applications at extreme scale. Before coming to the CEC, John was a researcher and resilience technical leader in the High Performance Computing (HPC) division at Los Alamos National Laboratory and a software engineer and application analyst for Raytheon Intelligence and Information Systems. He is a nationally recognized expert in resilience with 25 years of experience developing, porting, and running applications as an early adopter of many of the world's fastest supercomputers. He holds degrees in engineering and applied science and aerospace engineering from Caltech and Princeton University.

Originally from Frederick, MD, Beatrice Garcia is a Freshman Computer Science major and a Center for Women in Technology (CWIT) Scholar.

About Beatrice

When did you become interested in Computer Science? I've always liked computers and technology in general. I was always tinkering with the next new gadget. So, I decided to take a computer science class in high school, Introduction to Programming Concepts. We programmed in Java and I loved it. Sounds dorky, I know.

What area of Computer Science interests you the most? I love cyber security and I would love to explore bioinformatics. I have not taken any Biology classes yet, but I'm really interested in building software for the biology/medical field. As for cyber security, I think it's an integral part of our society nowadays because everything is being digitized and we need that security.

What Computer Science courses did you take in high school. How did those influence your choice of major? In high school, I took Introduction to Programming Concepts and AP Computer Science. No one really influenced me in taking those classes but my high school teacher was a huge influence in me majoring in Computer Science. She was a great teacher and really made the class a lot of fun.

What is your dream job? I would love to work for Google because they come up with the most innovative products. For example, the Chromebook. I've also heard about the amazing way Google treats their employees. They even have a program in Women in Leadership.

About being a CS major

What is the best part about being a CWIT Scholar? The absolute best thing about being a CWIT is the sense of community. Prior to entering freshman year, we went through a retreat. The retreat was really helpful because by the time classes started,  we already knew each other. So, college wasn't as intimidating as it could've been. In addition to already having friends as soon as you stepped onto campus, you already have an academic community supporting you. We instantly took advantage of study groups and helping each other with homework.

What classes are you taking? Right now, I'm taking Calculus I, Computer Science I for Computer Science Majors, Introduction to Gender/Women Studies, First-Year Experience, and English: Composition. I'm excited about taking CMSC 345: Software Design and CMSC 421: Operating Systems.

Are you part of any on-campus clubs, organizations, teams, or labs? Since this is my first semester as a college student, I actually did not sign up with as many clubs as I wanted because I wanted to test out the water first. Right now, I am a member of the Oxfam Club, which is an organization that helps build a future without poverty. I am a CWIT Scholar (Center of Women in Technology) and we try to promote gender diversity and equality in male-dominated technology fields. I'm also part of the Society of Women Engineers and for fun, I like to do yoga!

About life at UMBC

What is your favorite part about college so far? My favorite part of college is having more responsibility for myself. I know that I'm responsible for myself, so as long as I keep being level-headed and try my best, I will be fine. I've been constantly told that college is what you make of it and I will take advantage of that.

What is the best part about campus life at UMBC? I love that everyone on UMBC is mature and has an intention to succeed. But, we know how to have fun, too! The Students Events Board comes up with greatest events and they make sure you always have something fun to do!

What is your favorite spot on campus? I love walking by the pond or sitting at the ledges by the library because it's so peaceful and the landscape is beautiful.

Where can you get the best coffee/lunch/ food or beverage of choice? For the best coffee, I always go to Starbucks. But for breakfast, I always go to the Coffee Shop in the Administration Building. The ladies who work there are so nice and they have great food!

On-Campus Interviews offer students a chance to conveniently interview for professional positions on campus.  Employers travel to our campus for the specific purpose of interviewing preselected students for currently open positions.  This is a great opportunity to interview with employers specifically interested in UMBC students and offers the advantage of a smaller applicant pool.  Interviews take place during the fall and spring. The logistics (viewing positions, applying, signing up for interview time slots, etc.) are all handled via UMBCworks.

3:00 p.m. Thursday, 1 November 2012, ITE 456, UMBC

The goal of the Argonne Leadership Computing Facility (ALCF) is to extend the frontiers of science by solving problems that require innovative approaches and the largest-scale computing systems. ALCF’s current production computer has over 150,000 cores, and the system currently being readied for production – Mira, an IBM Blue Gene/Q system — has nearly one million cores.  How does one program such systems?  Are current software tools such as MPI and OpenMP available for such systems. Are scientific and engineering applications able to scale to such levels of parallelism?   Is resilience a new concern for 1,000,000 production codes on Mira This talk will address these questions and describe a sampling of projects that are using ALCF systems in their research.  Finally, the ways to gain access to ALCF resources will be presented.

Paul Messina is Director of Science at the ALCF. Dr. Messina guides the ALCF science teams using the IBM Blue Gene systems. In 2002-2004, he served as Distinguished Senior Computer Scientist at Argonne and as Adviser to the Director General at CERN (European Organization for Nuclear Research). Previously at Caltech, Dr. Messina served as Director of the Center for Advanced Computing Research, as Assistant Vice President for Scientific Computing, and as Faculty Associate for Scientific Computing. He led the Computational and Computer Science component of Caltech’s research project funded by the Academic Strategic Alliances Program of the Accelerated Strategic Computing Initiative. He also acted as Co-principal Investigator for the National Virtual Observatory and TeraGrid. At Argonne, he held a number of positions from 1973-1987 and was the founding Director of the Mathematics and Computer Science Division.
