3D XPoint is a dramatic new memory technology developed jointly by Intel and Micron. Intel claims that 3D XPoint is 1,000 times faster than NAND, has 1,000 times its endurance, and is 10 times denser than DRAM. Thus, this non-volatile computer storage medium could significantly disrupt current HPC technologies. This technology is more than just […]

The programming language Fortran has been in existence since 1957, and a large percentage of software that runs on HPC systems worldwide is written, at least in part, in Fortran. Since it has been in existence for so long, and so many scientists and engineers learned it early in their careers and have utilized it […]

There’s a big difference between basic system monitoring and performance monitoring. In the world of HPC, this distinction is greatly magnified. In the former case, monitoring often boils down to checking binary indicators to make sure system components are up or down, on or off, available or not. Red light/green light monitoring is certainly a […]

As HPC architectures continue to evolve and offer ever-increasing performance, it has become imperative to adapt existing software in order to fully harness that power. As discussed in an earlier post, the architectural approach to parallelism has come full circle in many ways. Nonetheless, MPI remains a fixture in HPC software design, and finding ways […]

In HPC, dealing with change-related problems is inevitable. But dealing with unauthorized change is unacceptable. Here’s why.

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 […]

We’ve been talking about how baselining and benchmarking helps optimize performance of your HPC system. Last time, we discussed the importance of maintaining a set of consistent benchmarks so you can analyze the performance of your HPC system throughout its lifetime. In this post, we’ll cover some specific baselining tips. Baselining should always start with […]

As a professional with access to a high performance computing environment, you already know it represents a scarce, precious, and expensive resource. You may have to schedule time in advance, and only get to work with the cluster for a limited period of time. You want to make the best possible use of HPC when […]

Vector instructions, once a powerful performance innovation of supercomputing in the 1970s and 1980s became an obsolete technology in the 1990s. But like the mythical phoenix bird, vector instructions have arisen from the ashes. Here is the history of a technology that went from new to old then back to new. But first, a few […]

HPC Systems are frustratingly complex beasts to tame. Competing interests from hardware and software support teams, coupled with demands from IT security compliance, can make having “consistency” in a cluster tough to achieve. Baselining is the natural answer. With baselining, we set a series of “custom” benchmarks. By custom, I mean they are a given […]
