In this video, Maurizio Davini from the University of Pisa describe how the University works with Dell EMC and Intel to test new technologies, integrate and optimize HPC systems with Intel HPC Orchestrator software. “We believe these two companies are at the forefront of innovation in high performance computing,” said University CTO Davini. “We also share a common goal of simplifying HPC to support a broader range of users.”
Today Mellanox announced that Spectrum Ethernet switches and ConnectX-4 100Gb/s Ethernet adapters have been selected by Baidu, the leading Chinese language Internet search provider, for Baidu’s Machine Learning platforms. The need for higher data speed and most efficient data movement placed Spectrum and RDMA-enabled ConnectX-4 adapters as key components to enable world leading machine learning […]
The two methods of scaling processors are based on the method used to scale the memory architecture and are called scaling-out or scale-up. Beyond the basic processor/memory architecture, accelerators and parallel file systems are also used to provide scalable performance. “High performance scale-up designs for scaling hardware require that programs have concurrent sections that can be distributed over multiple processors. Unlike the distributed memory systems described below, there is no need to copy data from system to system because all the memory is globally usable by all processors.”
In this video, a new NASA supercomputer simulation depicts the planet and debris disk around the nearby star Beta Pictoris reveals that the planet’s motion drives spiral waves throughout the disk, a phenomenon that greatly increases collisions among the orbiting debris. Patterns in the collisions and the resulting dust appear to account for many observed features that previous research has been unable to fully explain.
A new site developed by Tin H compares the HPC virtualization capabilities of Docker, Singularity, Shifter, and Univa Grid Engine Container Edition. “They bring the benefits of container to the HPC world and some provide very similar features. The subtleties are in their implementation approach. MPI maybe the place with the biggest difference.”
Thomas Schulthess from CSCS gave this Invited Talk at SC16. “Experience with today’s platforms show that there can be an order of magnitude difference in performance within a given class of numerical methods – depending only on choice of architecture and implementation. This bears the questions on what our baseline is, over which the performance improvements of Exascale systems will be measured. Furthermore, how close will these Exascale systems bring us to deliver on application goals, such as kilometer scale global climate simulations or high-throughput quantum simulations for materials design? We will discuss specific examples from meteorology and materials science.”
A team of international scientists have found a way to make memory chips perform computing tasks, which is traditionally done by computer processors like those made by Intel and Qualcomm. This means data could now be processed in the same spot where it is stored, leading to much faster and thinner mobile devices and computers. This type of chip is one of the fastest memory modules that will soon be available commercially.
The TOP500 list is a very good proxy for how different interconnect technologies are being adopted for the most demanding workloads, which is a useful leading indicator for enterprise adoption. The essential takeaway is that the world’s leading and most esoteric systems are currently dominated by vendor specific technologies. The Open Fabrics Alliance (OFA) will be increasingly important in the coming years as a forum to bring together the leading high performance interconnect vendors and technologies to deliver a unified, cross-platform, transport-independent software stack.
Singapore-based publisher Asian Scientist has launched Supercomputing Asia, a new print title dedicated to tracking the latest developments in high performance computing across the region and making supercomputing accessible to the layman. “Aside from well-established supercomputing powerhouses like Japan and emerging new players like China, Asian countries like Singapore and South Korea have recognized the transformational power of supercomputers and invested accordingly. We hope that this new publication will provide a unique insight into the exciting developments in this region,” said Dr. Rebecca Tan, Managing Editor of Supercomputing Asia.
In this video from SC16, Janet Morss from Dell EMC and Hugo Saleh from Intel discuss how the two companies collaborated on accelerating CryoEM. “Cryo-EM allows molecular samples to be studied in near-native states and down to nearly atomic resolutions. Studying the 3D structure of these biological specimens can lead to new insights into their functioning and interactions, especially with proteins and nucleic acids, and allows structural biologists to examine how alterations in their structures affect their functions. This information can be used in system biology research to understand the cell signaling network which is part of a complex communication system.”
