FAQs on HPC: Dr. Bill Nitzberg, Altair Engineering


High-performance computing (HPC), which has remained the exclusive playground for large enterprises and university researchers till recently, still raises lots of questions for engineers and designers. I don’t have all the answers, but I know a few people who do. One of them is Dr. Bill Nitzberg, CTO of PBS Works, Altair Engineering.

For my print article titled “On-Demand Computing with PBS Works” (October 2010), I interviewed Nitzberg’s colleague Robert Walsh, Altair’s director of business development for PBS GridWorks. In the podcast below, Nitzberg picks up where Walsh left off to explain:

  • how the weakest link in a HPC cluster might drag down the whole setup;
  • how you can remotely tap into Altair’s HPC resources from PBS Works;
  • why Altair is currently not charging customers extra for scheduling works on the GPU;
  • why estimating run time on HPC applications is such a challenge;
  • and more.
