TSUBAME2: How to Manage a Large GPU-Based Heterogeneous Supercomputer

Dr. Satoshi Matsuoka, University of Tokyo

Satoshi Matsuoka gave this talk at the PBS Works User Group this week. “The Tokyo Tech. TSUBAME2 supercomputer is one of the world’s leading supercomputer, ranked as high as #4 in the world on the Top500 and recognized as the “greenest supercomputer in the world” on the Green 500. With the GPU upgrade in 2013, it still sustains high performance (5.7 Petaflops Peak) and high usage (nearly 2000 registered users). However, such performance levels have been achieved with pioneering adoption of latest technologies such as GPUs and SSDs that necessitated non-traditional strategies in resource scheduling.”

Univa Grid Engine Adds Docker Support


Today Univa announced the Univa Grid Engine Container Edition, which fully incorporates Docker containers into the Univa Grid Engine resource manager. The Container Edition features the unique ability to run containers at scale and blend containers with other workloads and supports heterogeneous applications and technology environments.

Six Strategies for Maximizing GPU Clusters

In a perfect world, there would be one version of all compilers, libraries, and profilers. To make things even easier, hardware would never change. However, technology marches forward, and such a world does not exist. Software tool features are updated, bugs are fixed, and performance is increased. Developers need these improvements but at the same time must manage these differences.

Bright Computing Collaborates on OpenHPEC Accelerator Suite


Today Curtiss-Wright Corporation announced that its Defense Solutions division is collaborating with leading High Performance Computing software vendor Bright Computing to bring its supercomputing software tools to the embedded Aerospace & Defense market as part of Curtiss-Wright’s recently announced OpenHPEC Accelerator Suite of best-in-class software development tools.

Australian Bureau of Meteorology to Manage Cray Workloads with Altair PBS Pro


Today Altair announced that its PBS Professional has been chosen to manage workloads for the new Cray supercomputer to be installed at the Bureau of Meteorology (BoM), Australia’s national weather, climate and water agency.

Best Practices for Maximizing GPU Resources in HPC Clusters

HPC developers want to write code and create new applications. The advanced nature of HPC often requires that this process be associated with specific hardware and software environment present on a given HPC resource. Developers want to extract the maximum performance from HPC hardware and at the same time not get mired down in the complexities of software tool chains and dependencies.

Strategies for Managing High Performance GPU Clusters

When discussing GPU accelerators, the focus is often on the price-to-performance benefits to the end user. The true cost of managing and using GPUs goes far beyond the hardware price, however. Understanding and managing these costs helps provide more efficient and productive systems.

Bright Computing Grows its Channel for Cluster Management


Bright Computing has announced an expansion of its global network of channel partners, local resellers, local system integrators, as well as original equipment manufacturers (OEMs). The relationships are leading to collaborations resulting in increased business opportunities in its core Western, Central and Eastern European markets, Russia, the Middle East, and Africa.

Adept Project Looks at Using Software to Conserve Energy


In this special guest feature, Tom Wilkie from Scientific Computing World writes that software approaches to energy efficiency in HPC may yield unexpected improvements in the hardware of next-generation mobile phone networks. “Adept, a European research project addressing the energy-efficient use of parallel technologies, is expected to release a set of benchmarks that it has developed to characterize the energy consumption of programming models on different architectures.”

“HPC in a Box” from the Docker Workshop at ISC 2015

Christian Kniep

In this video from the Docker Workshop at ISC 2015, Christian Kniep from QNIB Solutions shows how he uses Docker in his efforts to provide a HPC software stack in a box, encapsulating each layer in the HPC stack within a Linux Container.
