Title: " Real-Time Processing on GPU-based Systems: Experiences and Challenges "
Lecturer: Assoc. Prof. Anne C. Elster, Computer & Info. Science (IDI) at the Norwegian Univ. of Science & Technology (NTNU)
Abstract
GPUs are now massive floating-point stream processors that offer a source of energy-efficient compute power on our laptops and desktops. Recent development of tools such as CUDA and OpenCL have made it much easier to utilize the computational power these systems offer. However, in order to optimally harness the the power of these GPU-based systems, there still are many challenges to overcome. In this talk, several issues related to our experiences applications that can benefit from real-time processing of data on GPUs, will be discussed. These include real-time medical imaging, e.g. for ultrasound-guided discovery and surgery, real-time seismic CT image enhancement, and using GPUs for real-time compression of seismic data in order to lower I/O latency. This talk will highlight the work our research group has been involved dating back from 2006 through today.
Keywords of the presentation: GPUs, real-time applications, medical imaging, geological imaging, seismic processing.
Biography
Dr. Anne C. Elster (Senior Member IEEE 2000) is an Assoc. Prof. of Computer & Info. Science (IDI) at the Norwegian Univ. of Science & Technology (NTNU) in Trondheim, where she founded HPC-Lab, has supervised 40+ graduate students and hosted several visitors. Her research focus is Heterogeneous and Parallel Computing, including GPU computing. She recently served as one of four IDI Section Heads, and is one of four Working Group leaders of EU COST Action IC0805: Open European Network for High Performance Computing on Complex Environments.
Dr. Elster was born near the Arctic Circle in Mo i Rana, Norway. After completing her secondary education in Porsgrunn, Norway, she received a one-year scholarship to the Univ. of Oregon. Curious to find out how computers really work, she then transferred to the Univ. of Massachusetts at Amherst where she received a B.S. in Computer Systems Engineering cum laude. While there, she also took several courses in computer science and honors mathematics. She also holds M.S. and Ph.D. degrees in EE from Cornell University where she had a lot of fun at their supercomputer center exploring various HPC systems in the late 80s and early 90s. She worked for Schlumberger in Austin 1994-97, then part-time at Univ. of Texas at Austin in 1997-2000 and founded ACENOR Inc. in 2000 and joined NTNU in 2001.
She served on the MPI standards committees (MPI and MPI-2), on the Research Council of Norway.s HPC committee (TRP III, 2003-2004) and on the Danish Resarch Council's Expert Panel for Research Infrastructure (2007-2010). She is is currently spending her sabbatical for 2010/11 at the ECE Dept. at the University of Texas at Austin. Dr. Elster has recently given several invited talks incl. at IMA Workshop: High Performance Computing and Emerging Architectures , Jan. 2011 in Minnesota.
