Searching for Human Brain Memory Molecules with the Piz Daint Supercomputer

Scientists at the University of Basel are using the Piz Daint supercomputer at CSCS to discover interrelationships in the human genome that might simplify the search for “memory molecules” and eventually lead to more effective medical treatment for people with diseases that are accompanied by memory disturbance. “Until now, searching for genes related to memory capacity has been comparable to seeking out the proverbial needle in a haystack.”

PRACE Awards 1.7 Thousand Million Core Hours for Research Projects in Europe

Today the European PRACE initiative announced that 46 Awards from their recent 15th Call for Proposals total up to nearly 1.7 thousand million core hours. The 46 awarded projects are led by principal investigators from 12 different European countries. “Of local interest this time around, the awarded projects involve co-investigators from the USA (7) and Russia (2). All information and the abstracts of the projects awarded under the 15th PRACE Call for Proposals are now available online.”

SC17 Panel Preview: How Serious Are We About the Convergence Between HPC and Big Data?

SC17 will feature a panel discussion entitled How Serious Are We About the Convergence Between HPC and Big Data? “The possible convergence between the third and fourth paradigms confronts the scientific community with both a daunting challenge and a unique opportunity. The challenge resides in the requirement to support both heterogeneous workloads with the same hardware architecture. The opportunity lies in creating a common software stack to accommodate the requirements of scientific simulations and big data applications productively while maximizing performance and throughput.

Interview: Piz Daint Supercomputer advances to the #3 position on the TOP500

In this video from PASC17 in Lugano, Michele De Lorenzi from CSCS discussed the recent advancement of Piz Daint supercomputer to the #3 position on the TOP500. After that, he describes the mission of the PASC conference and the location of PASC18 next year.

HPC Workflows Using Containers

“In this talk we will discuss a workflow for building and testing Docker containers and their deployment on an HPC system using Shifter. Docker is widely used by developers as a powerful tool for standardizing the packaging of applications across multiple environments, which greatly eases the porting efforts. On the other hand, Shifter provides a container runtime that has been specifically built to fit the needs of HPC. We will briefly introduce these tools while discussing the advantages of using these technologies to fulfill the needs of specific workflows for HPC, e.g., security, high-performance, portability and parallel scalability.”

A PCIe Congestion-Aware Performance Model for Densely Populated Accelerator Servers

“MeteoSwiss, the Swiss national weather forecast institute, has selected densely populated accelerator servers as their primary system to compute weather forecast simulation. Servers with multiple accelerator devices that are primarily connected by a PCI-Express (PCIe) network achieve a significantly higher energy efficiency. Memory transfers between accelerators in such a system are subjected to PCIe arbitration policies. In this paper, we study the impact of PCIe topology and develop a congestion-aware performance model for PCIe communication. We present an algorithm for computing congestion factors of every communication in a congestion graph that characterizes the dynamic usage of network resources by an application.”

Introduction to Data Science with Spark

The Data Science with Spark Workshop addresses high-level parallelization for data analytics workloads using the Apache Spark framework. Participants will learn how to prototype with Spark and how to exploit large HPC machines like the Piz Daint CSCS flagship system.

Introduction to GPUs in HPC

“This video is from the opening session of the “Introduction to Programming Pascal (P100) with CUDA 8″ workshop at CSCS in Lugano, Switzerland. The three-day course is intended to offer an introduction to Pascal computing using CUDA 8.”

Reflecting on the Goal and Baseline for Exascale Computing

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.”
