HPC Scalability: 4 Common Barriers, 10 Possible Solutions

By in Application Engineering on July 20, 2017

Scaling HPC applications on your hardware is a vital task in supercomputing. If an application can’t use all of the hardware devoted to it, then you have expensive equipment sitting idle and not doing anyone any good. When looking at scalability, it is important to first ensure that the problem can scale. In other words, […]

How HPC Scientific and Math Libraries Aid Researchers

By in Uncategorized on May 25, 2017

Scientists and researchers increasingly use high-performance computers, among other tools, to acquire, organize, and process data. As experts in their domains, it’s natural to expect them to be more productive and successful if their primary focus is on the frontiers of their fields of study rather than on deeply understanding their digital and computational tools. […]

The Role of IBM Spectrum Scale (aka GPFS) in the Enterprise

By in Uncategorized on April 21, 2017

IBM Spectrum Scale (formerly known as GPFS) is a high-performance, highly scalable global file system that provides a single namespace to data. Given its long history with high-performance computing (HPC) and data-intensive media and data stream serving applications, Spectrum Scale has traditionally been viewed as a niche data solution: complex to install, optimize, and maintain, […]

Large-Scale HPC Workflow Management at NCEP

By in Operations & Maintenance on March 3, 2017

Editor’s Note: RedLine Senior Program Analyst Kit Menlove contributed to this post. For industry and academia, managing workflows for large-scale data-intensive computational processes is a constant challenge. As every industry and scientific discipline becomes more reliant on ever increasingly complex and robust computational solutions, the ability to create repeatable and agile end-to-end processes becomes an […]

CMake: Manage Software Builds and Improves Portability

By in Application Engineering on February 6, 2017

There are many build systems available for software development, and if your software is still using the venerable Make system, it can certainly pay to investigate an upgrade. Kitware’s cross-platform CMake system is one such framework, and it offers a considerable improvement. At its base level, CMake offers a single approach to building your software […]

Using TAU to Profile and Identify HPC Bottlenecks

By in Application Engineering on September 21, 2016

For high-performance computing professionals, a deep understanding of how programs execute is vital. Often, that knowledge can spell the difference between making proper use of computing resources and meeting deadlines – or not. Keys to optimizing HPC resources include profiling program elements such as functions or subroutines and identifying and alleviating potential bottlenecks. Profiling refers […]
