NOAA’s National Centers for Environmental Prediction’s (NCEP) flagship numerical weather prediction system, the Global Forecast System (GFS) is used by meteorologists throughout the U.S. and around the world. The next upgrade to the GFS, version 16, is scheduled for implementation in February of 2021. Among other differences between this model and the current GFS, one […]
While public clouds have been used for HPC for at least the past decade, several key challenges have traditionally slowed the adoption of cloud computing for HPC: Slow, high-latency interconnects High virtualization overhead and poor isolation from other workloads Data staging challenges and costs (getting large data sets into and out of the cloud) Moving […]
While the annual SC conference is always a worthy experience, SC16 may have been the most rewarding ever – filled, as it was, with some fantastic insights from fellow HPC professionals, news on the latest technologies that will advance our industry, and the chance to catch up with colleagues and friends old and new. At […]
3D XPoint is a dramatic new memory technology developed jointly by Intel and Micron. Intel claims that 3D XPoint is 1,000 times faster than NAND, has 1,000 times its endurance, and is 10 times denser than DRAM. Thus, this non-volatile computer storage medium could significantly disrupt current HPC technologies. This technology is more than just […]
Vector instructions, once a powerful performance innovation of supercomputing in the 1970s and 1980s became an obsolete technology in the 1990s. But like the mythical phoenix bird, vector instructions have arisen from the ashes. Here is the history of a technology that went from new to old then back to new. But first, a few […]
