Simulating Global Atmosphere with NICAM on TSUBAME2.5 Using OpenACC


“OpenACC was applied to the a global high-resolution atmosphere model named NICAM. We executed the dynamical core test without re-writing any specific kernel subroutines for GPU execution. Only 5% of the lines of source code were modified, demonstrating good portability. The results showed that the kernels generated by OpenACC achieved good performance, which was appropriate to the memory performance of GPU, as well as weak scalability. A large-scale simulation was carried out using 2560 GPUs, which achieved 60 TFLOPS.”

Video: Teaching Machines to Diagnose Cancer


In this PBS video, Hari Sreenivasan reports on how tech firms are investing in the next generation of intelligent computer programs and in what ways the technology still lags behind humans. The report also takes a closer look at teaching machines to diagnose cancer.

Attacking HIV with Titan and Blue Waters


“The highly parallel molecular dynamics code NAMD was was one of the first codes to run on a GPU cluster when G80 and CUDA were introduced in 2007, and is now used to perform petascale biomolecular simulations, including a 64-million-atom model of the HIV virus capsid, on the GPU-accelerated Cray XK7 Blue Waters and ORNL Titan machines.”

E4-ARKA: ARM64+GPU+IB is Now Here


“E4 Computer Engineering has introduced ARKA, the first server solution based on ARM 64 bit SoC dedicated to HPC. The compute node is boosted by discrete GPU NVIDIA cards K20 with 10Gb ethernet and FDR InfiniBand networks implemented by default. In this presentation, the hardware configuration of the compute node is described in detail. The unique capabilities of the ARM+GPU+IB combination are described, including many synthetic benchmarks and application tests with particular attention to molecular dynamics software.”

Video: HPC Solution Stack on OpenPOWER


“This demo will show the capability of IBM OpenPOWER that can be the foundation of the complicated High Performance Computing complete solution. From the HPC cluster deployment, job scheduling, system management, application management to the science computing workloads on top of them, all these components can be well constructed on top of IBM OpenPOWER platform with good usability and performance. Also this demo shows the simplicity of migrating a complete x86 based HPC stack to the OpenPOWER platform.”

Video: From Lab to Enterprise – Growing the Lustre Ecosystem


“Lustre’s original feature set targeted the workflows of the leading DOE labs who funded and supported its development. As the Lustre ecosystem grows, the workflows Lustre must support are becoming increasingly diverse, demanding corresponding expansion of its core feature set and the subsystems that operate around it. This talk describes how Lustre is maturing and growing to support the sometimes conflicting demands imposed by this diversity and outlines some significant areas for future development with a view to promoting ongoing discussion in the community.”

Video: The Future of Interconnect with OpenPOWER


“ConnectX-4 EDR 100Gb/s with CAPI support tightly integrates with the POWER CPU at the local bus level and provides faster access between the POWER CPU and the network device. We will discuss the latest interconnect advancements that maximize application performance and scalability on OpenPOWER architecture, including enhanced flexible connectivity with the latest Mellanox ConnectX-3 Pro Programmable Network Adapter.”

Video: OpenACC for Fortran Programmers


“Learn how to program NVIDIA GPUs using Fortran with OpenACC directives. The first half of this presentation will introduce OpenACC to new GPU and OpenACC programmers, providing the basic material necessary to start successfully using GPUs for your Fortran programs. The second half will be intermediate material, with more advanced hints and tips for Fortran programmers with larger applications that they want to accelerate with a GPU. Among the topics to be covered will be dynamic device data lifetimes, global data, procedure calls, derived type support, and much more.”

Video: Soft RoCE Drivers


Soft-RoCE is the software implementation of the RoCE standard and compatible with any standard Ethernet networks.

Video: Docker, Monitoring, and SLURM Dashboards

Christian Kniep

“Based on a containerized HPC environment this talk shows of a state-of-the-art stack including performance monitoring, log event handling and GraphDB based inventory to provide insights into what is going on within a SLURM cluster. The framework used is QNIBTerminal incorporating the ELK stack, a graphite backend and neo4j as a GraphDB.”
