In the article “Is cloud computing fast enough for science?” Federal Computer Week magazine discusses early results from DOE’s Magellan cloud computing testbed with NERSC Director Kathy Yelick. “For the more traditional MPI applications there were significant slowdowns, over a factor of 10,” Yelick said. But for computations that can be performed serially, such as genomics calculations, there was little or no deterioration in performance in the cloud.
Yelick discusses cloud computing in more detail in “Uncovering Results in the Magellan Testbed” in HPC in the Cloud.
EnterTheGrid/Primeur magazine, a European online magazine for high performance computing and networking, interviewed John Shalf, head of NERSC’s Advanced Technologies Group, at ISC’10 in Hamburg. The resulting article, titled “It takes three to tango in exascale computing: memory, photonic interconnects and embedded processors,” discusses the Green Flash project and the future of supercomputing from the hardware side. On the software side, Shalf discussed native parallel programming languages with International Science Grid This Week in “Q & A — John Shalf talks parallel programming languages.”
