Open-source containers move toward high-performance computing

Open-source containers are moving in a direction that many of us never anticipated.

Long recognized as providing an effective way to package applications with all of their required components, some are also tackling one of the most challenging areas in the compute world today — high-performance computing (HPC). And while containers can bring a new level of efficiency to the world of HPC, they’re also presenting new ways of working for enterprise IT organizations that are running HPC-like jobs.

How containers work

Containers offer many advantages to organizations seeking to distribute applications. By incorporating an application’s many dependencies (libraries, etc.) into self-sustainable images, they avoid a lot of installation problems. The differences in OS distributions have no impact, so separate versions of applications don’t have to be prepared and maintained, thus making developers’ work considerably easier.

Open Source Containers in 2019

Open source containers are moving in a direction that many of us never anticipated. Long recognized as providing an effective way to package applications with all of their required components, some are also tackling one of the most challenging areas in the compute world today — high performance computing or “HPC”. And while containers can bring a new level of efficiency to the world of HPC, they’re also presenting new ways of working for enterprise IT organizations that are running HPC-like jobs.

Space data backbone gets U.S. approval

Soon we may have a space-based optical backbone capable of transferring data 1.5 times faster than Earth-based terrestrial fiber, now that the Federal Communications Commission (FCC) has given LeoSat the go-ahead to start its build-out.

Moving “large quantities of data quickly and securely around the world, is fast outpacing the infrastructure in place to carry it,” says LeoSat in a press release announcing its FCC market-access grant last month. Upcoming LeoSat, will be a “a backbone in space for global business,” the company says.
