As the countdown to Exascale continues, Exascale-like storage problems are already showing up in today’s massively parallel, heterogeneous HPC systems. Historically, storage and I/O have kept pace with growing system demands, but, because of the limitations of spinning media and the cost of solid state storage technologies, storage performance improvements have come at a disproportionately higher cost and lower efficiency than their compute counterparts.
“As the name indicates: A NAM is basically a storage device plugged into the interconnect network of a Cluster. That sounds pretty simple and straightforward. But the underlying technology is quite new and exciting and the NAM concept enables entirely new approaches for using memory as a shared resource.”
“Exascale levels of computing pose many system- and application-level computational challenges. Mellanox as a provider of end-to-end communication services is progressing the foundation of the InfiniBand architecture to meet the exascale challenges. This presentation will focus on recent technology improvements which significantly improve InfiniBand’s scalability, performance, and ease of use.”
“The business case for exascale in O&G is extremely compelling, and — as anyone who has read Daniel Yergin’s “The Prize” will appreciate — goes to the very core of why IOCs exist. In the search for oil and gas in the Gulf of Mexico — one of the richest hydrocarbon basins in the world that continues to reinvent itself for exploration plays — the biggest prizes lie in ultra-deep water. In a deeply submerged area about 300 miles southwest of New Orleans and extending into Mexico waters, rock formations from the Paleogene period, also known as the Lower Tertiary, represent the leading edge of deep-water oil discovery. “
Today insideHPC announced that the organization is seeking nominations for the HPC Vanguard Award. Launched by The Exascale Report in 2013, the award recognizes critical leaders in the HPC community’s strategic push to achieve exascale levels of supercomputing performance. The HPC Vanguard Award recognizes leadership in driving the HPC community,” said Rich Brueckner, President of insideHPC. “As the name suggests, Vanguards consistently push the envelope and are always open to new, innovative thinking.”
“In terms of the hardware, one of the biggest successes surely was to make the Intel Xeon Phi boot via the Extoll network. This might not sound so special, but for the DEEP project it is – because this basically is the essential milestone for proving our architectural concept: The Cluster-Booster approach. In traditional heterogeneous architectures the accelerators cannot boot without a host CPU. Our aim was to develop a cluster – made up of usual CPUs – and a booster – made up of accelerators – that can both act autonomously while being interconnected via two networks.”
NERSC has accepted a selection of key DOE science projects into its NERSC Exascale Scientific Applications Program, a collaborative effort in which NERSC will partner with code teams to prepare for the NERSC-8 Cori manycore architecture. NESAP represents an important opportunity for researchers to prepare application codes for the new architecture and to help advance […]
