In this video from the 2017 MVAPICH User Group, Dan Stanzione from TACC presents: MVAPICH at Petascale: Experiences in Production on the Stampede System.

“While much of the emphasis in machine learning, high end computing, and cloud computing is about the “processor wars” and the choice of GPU or CPU for particular algorithms, high performance interconnects remain an absolutely essential ingredient of achieving performance at large scale. This talk will focus on the role MVAPICH has played at the Texas Advanced Computing Center (TACC) over multiple generations of multiple technologies of interconnect, and why it has been critical not only in maximizing interconnect performance, but overall system performance as well. The talk will include examples of how poorly tuned interconnects can mean the difference between success and failure for large systems, and how the MVAPICH software level continues to provide significant performance advantages across a range of applications and interconnects.”

Dr. Stanzione is the Executive Director of the Texas Advanced Computing Center (TACC) at The University of Texas at Austin since July 2014, previously serving as Deputy Director. He is the principal investigator (PI) for a National Science Foundation (NSF) grant to deploy and support Stampede2, a large scale supercomputer, which will have over twice the system performance of TACC’s original Stampede system. Stanzione is also the PI of TACC’s Wrangler system, a supercomputer for data-focused applications. For six years he was co-director of CyVerse, a large-scale NSF life sciences cyberinfrastructure. Stanzione was also a co-principal investigator for TACC’s Ranger and Lonestar supercomputers, large-scale NSF systems previously deployed at UT Austin. Stanzione received his bachelor’s degree in electrical engineering and his master’s degree and doctorate in computer engineering from Clemson University.
