In this video from WestGrid in Canada, Dr. Yussanne Ma from the Michael Smith Genome Sciences Centre describes how high performance computing supports her research group’s work, highlighting a recent project where a bioinformatics pipeline was built for the personalized onco-genomics project (POG) at the BC Cancer Agency.

Podcast: Cray’s Steve Scott on Programming for the Next Decade

Steve Scott

“Our computing systems continue to evolve, providing significant challenges to the programming teams managing large, long-lived projects. Issues include rapidly increasing on-node parallelism, varying forms of heterogeneity, deepening memory hierarchies, growing concerns around resiliency and silent data corruption, and worsening storage bottlenecks.”

Video: Enabling OpenACC Performance Analysis

Learn how OpenACC runtimes also exposes performance-related information revealing where your OpenACC applications are wasting clock cycles. The talk will show that profilers can connect with OpenACC applications to record how much time is spent in OpenACC regions and what device activity it turns into.

Call for Papers: Workshop on Accelerator Programming using Directives

The 2nd Workshop on Accelerator Programming using Directives has issued its Call for Papers. The WACCPD Workshop takes place Nov. 16 in Austin in conjunction with SC15.

HPC News Bytes for May 15, 2015

While we’re always on the lookout for HPC news, not everything makes it to the front page. Here are some notable items from this week.

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.”

Gather Scatter Operations

D-Wave Systems reports that the company is designing and building the world’s most advanced quantum computers with help from engineering simulation solutions from ANSYS. This next generation of supercomputers uses quantum mechanics to massively accelerate computation and has the potential to solve some of the most complex computing problems facing organizations today.

How HPC is increasing speed and accuracy

Mark Gunn, Sr. VP, One Stop Systems

The overwhelming task of high performance computing today is the processing of huge amounts of data quickly and accurately. Just adding greater numbers of more intensive, sophisticated servers only partially solves the problem.

Video: Teaching Machines to Diagnose Cancer
