“OpenACC and OpenMP provide programmers with two good options for portable, high-level parallel programming for GPUs. This talk will discuss similarities and differences between the two specifications in terms of programmability, portability, and performance.”

UPC and OpenSHMEM PGAS Models on GPU Clusters

DK Panda, Ohio State University

“Learn about extensions that enable efficient use of Partitioned Global Address Space (PGAS) Models like OpenSHMEM and UPC on supercomputing clusters with NVIDIA GPUs. PGAS models are gaining attention for providing shared memory abstractions that make it easy to develop applications with dynamic and irregular communication patterns. However, the existing UPC and OpenSHMEM standards do not allow communication calls to be made directly on GPU device memory. This talk discusses simple extensions to the OpenSHMEM and UPC models to address this issue.”

“We present a state-of-the-art image recognition system, Deep Image, developed using end-to-end deep learning. The key components are a custom-built supercomputer dedicated to deep learning, a highly optimized parallel algorithm using new strategies for data partitioning and communication, larger deep neural network models, novel data augmentation approaches, and usage of multi-scale high-resolution images.”

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: Accelerating OpenPOWER Using NVM Express SSDs and CAPI

“We present results for a platform consisting of an NVM Express SSD, a CAPI accelerator card and a software stack running on a Power8 system. We show how the threading of the Power8 CPU can be used to move data from the SSD to the CAPI card at very high speeds and implement accelerator functions inside the CAPI card that can process the data at these speeds.”

ISC to Showcase Women in HPC

With a BoF session and a special workshop on Women in HPC, the issue of gender diversity will be front and center at ISC High Performance in Frankfurt. “Improving diversity in the workforce is generally recognized as essential to meet the needs of a growing industry, improve European competitiveness, and improve productivity.”

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.
