“In this video, Mark O’Connor from Allinea demonstrates how the company’s Performance Reports software generates easy-to-understand pages that characterize the performance of HPC application runs.”

Defining HPC Cluster Success Factors

HPC Cluster Success

The true cost of operating a successful HPC cluster extends beyond the initial hardware purchase or power budget. A truly well run and efficient cluster also minimizes the amount of time, resources, and level of expertise administrators need to detect and mitigate issues within the cluster.

Today Allinea Software today announced that the company’s Allinea DDT 4.2.1 debugging software has been tailored to offer full support for NVIDIA CUDA 6

Are There Potholes on the Road to Exascale?

John Barr

“When OpenACC first appeared it made sense to use this forum to experiment with new approaches while the use of GPUs in HPC was evolving rapidly, with the expectation that the best ideas would then be reintroduced into OpenMP. But OpenMP and OpenACC now seem to be diverging. Indeed, a comparison of OpenACC and OpenMP on the OpenACC web site says “efforts so far to include support for GPUs in the OpenMP specification are — in the opinions of many involved — at best insufficient, and at worst misguided.”

With Bulk, CUDA Thrust API Now Supports Streams and Concurrent Tasks

Rob Farber

“Bulk leverages Hyper-Q and CUDA streams to run concurrent tasks on the GPU. It lets the programmer describe a parallel task (e.g. sort, for_each, reduction, etcetera) as a hierarchical grouping of execution agents.”

Call for Participation: Women Who Cuda

Lorena Barba

“It’s a good way to remind people that women write code, participate in open-source projects, and invent things,” Barba said. “It’s important to make the technology world more attractive to female students and show them examples of women who are innovators.”

The Holland Computing Center HPC support team at the University of Nebraska is using Allinea Software’s unified debugging and profiling tools to help users speed up their scientific computing. With the need to support four clusters and total of 20,000 compute cores, Nebraska’s HPC support team provides assistance to many users of large MPI applications […]

Why the Industry Needs More HPC Performance Tool Developers

Dr. Ing. Bernd Mohr

Over at the ISC Blog, Bernd Mohr writes that HPC programmers are still in demand thanks to the complexity of today’s hybrid supercomputers. So, in reality programming HPC systems is still very complex and if you manage to create a correctly working program, it does not automatically mean you get a very efficiently working program. […]

Don’t Play MacGyver With Your Data Center Cluster

Dr. Matthijs van Leeuwen, Founder and CEO of Bright Computing

MacGyver is a character famous for getting out of tough situations by coming up with a makeshift solution from whatever bits and pieces he found laying around. That’s no way to manage a critical part of your organization’s infrastructure.
