Abstract

This would provide a summary of how IBM recently the first to achieve this significant milestone on what is now the no1 system on www.top500.org and the challenges/successes we experienced in doing so. We would highlight the trend toward thinking outside of the box and leveraging the best of technologies to build hybrid systems. We would also highlight the challenges we see into the future in achieving massive scaling of applications/software necessary to do break-through Science and what we are doing to tackle those challenges and suggestions on how the e-research community can likewise do so.

About the speaker

Thomas A. Liebsch is a Senior Technical Staff Member, and works in the Systems and Technology division of IBM. His main interests include architecting system designs for massively parallel IO communication, and associated embarrassingly parallel computation scaling challenges. With various IBM teams, he has architected numerous parallel systems that allow for efficient fast fourier transforms, and efficient all-to-all communications with impressive bi-sectional bandwidths. His recent works on IO bandwidths improvements for low latency standard communication protocols, via sockets, have been deployed in most of IBM’s systems. Currently, Mr. Liebsch is the development chief engineer for the IBM BlueGene supercomputer systems. Thomas Liebsch joined IBM in 1988 after holding a teaching position at South Dakota State University. During this time at SDSU, he received his M.S. in Electrical Engineering. His additional background includes working at Boeing Commercial Airplane company for 2 years, as a numerical analysis, and mathematical modelling for the 757/767 aircraft, after receiving his B.S. in Electrical Engineering with minors in Math, and Computer Science at SDSU.
