Podcast: Interview with IBM's Don Grice from The Exascale Report

In this exclusive feature audio interview, IBM Distinguished Engineer and Chief Engineer for Road Runner, Don Grice, discusses photonics technology, co-design, and Blue Gene with a pragmatic approach to exascale R&D.

Don addresses the following questions:

  • Back in November, IBM talked about a breakthrough in allowing chips to communicate at faster speeds using pulses of light – and it was said that this photonics technology could boost processing capabilities to a million trillion calculations per second, an exaflop. Has there been any substantial progress in this area – and do you still think this could be a key factor in exascale development?
  • What’s the timeframe we are looking at for this type of research – and are there implications beyond the quest for exascale?
  • Can you tell us more about IBM’s exascale research labs?
  • What is IBM’s view of Co-Design, an approach many have said is absolutely essential to achieving exascale computation, and are your teams involved in any co-design efforts related to exascale research?
  • How is IBM organized around exascale? Where is the ownership?
  • Where does Blue Gene fit in the exascale landscape?
  • Community leaders have stated for quite some time that compilers would likely be a critical component to actually achieving exascale levels of computation. What is your position on this today – is there anything you can share with our readers regarding compiler research with an eye to exascale?
  • At what point do you see Cloud Computing playing a role in exascale computing? Do you see their paths converging?
