New OpenPOWER Acceleration Center Opens in France

Europe’s second POWER Acceleration and Design Center is located at the IBM Client Center in Montpellier, France where developers can get hands-on, technical assistance for creating OpenPOWER-based high performance computing apps.

Today IBM announced the establishment of a new POWER Acceleration and Design Center in Montpellier, France. Launched in collaboration with Nvidia and Mellanox, the new center will advance the development of data-intensive research, industrial, and commercial applications.

Podcast: Geoffrey Hinton on the Rise of Deep Learning

CHY4y4HUcAEq0MR

“In Deep Learning what we do is try to minimize the amount of hand engineering and get the neural nets to learn, more or less, everything. Instead of programing computers to do particular tasks, you program the computer to know how to learn. And then you can give it any old task, and the more data and the more computation you provide, the better it will get.”

Students Win ASC15 Competition with K80 GPUs

ASC15 Winners from Tsinghua University

Over at the Nvidia Blog, George Middleton writes that Tesla K80 GPUs powered the winning team from Tsinghua University at the recent ASC15 International Student Cluster Competition.

Video: Three Ways to Debug Parallel CUDA Applications

0

“This talk will introduce these three debugging techniques and provide some suggestions on selecting the optimal approach for a variety of debugging scenarios such as hangs, numerical errors, and crashes. Specific examples will be given using the TotalView debugger but the concepts covered may apply to other debugging tools such as GDB and the NVIDIA NSIGHT debugger.”

Alternatives to x86: Future Processing Technologies

Robert Roe

In the second article in his series on future hardware for HPC, Robert Roe from Scientific Computing World looks at alternatives to the x86, including server on a chip and OpenPower.

Achieving Near-Native GPU Performance in the Cloud

John Paul Walters

“In this session we describe how GPUs can be used within virtual environments with near-native performance. We begin by showing GPU performance across four hypervisors: VMWare ESXi, KVM, Xen, and LXC. After showing that performance characteristics of each platform, we extend the results to the multi-node case with nodes interconnected by QDR InfiniBand. We demonstrate multi-node GPU performance using GPUDirect-enabled MPI, achieving efficiencies of 97-99% of a non-virtualized system.”

Simulating Global Atmosphere with NICAM on TSUBAME2.5 Using OpenACC

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.”
