Direct Contact Liquid Cooling Continues its Move into the Data Center

In the world of HPC, continuous improvements in performance are key to keeping up with today’s demanding workloads. But it’s hard to realize the true potential of your IT infrastructure when your datacenter is running out of cooling capacity. Space and power density problems limit your ability to pack more compute into smaller spaces and make better use of your existing data center real estate.

Four Challenges Facing Exascale Application Prep

Worry over readying HPC applications for exascale computing isn’t new and various efforts are underway. Whether they are sufficient is a matter of debate. A major stumbling block, of course, is no one knows precisely what exascale architecture will look like. A recent paper (June 9) on arXiv.org from IBM Research and several European academic researchers proposes an Read more…

Cluster Lifecycle Management: Recycle and Rebirth

This column series has focused on the steps that need to be taken to keep your system running efficiently so that end users have productive experiences and your organization gains a positive ROI on its investment in HPC technology. But even with your clusters running at peak efficiency, the day will come – could be within a few months or could be four years – when you will start seeing the need to upgrade the system.

Fixating on Exascale Performance Only Is a Bad Idea

Few in the computing industry dispute that achieving ‘exascale’ performance is worthy on its own merits. But fixating only on the magic milestone (10^18 FLOPS) misses an important point – HPC as currently practiced, even at the exascale level, won’t solve the grand challenges in science and society contends Dr. Sadasivan Shankar, Harvard University visiting lecturer Read more…
