A Container for HPC – Docker, UberCloud, Shifter, and Singularity

AdminContainers have become an important part of the IT industry because they are more efficient than full (hardware-level) virtualization, and they dramatically improve software packageability, portability, access and use of application software and tools, and software support and maintenance. In his Admin-Magazine article, Jeff Layton explains the difference between virtual machines versus Linux containers and differentiates between ‘hardware-level virtualization’ and ‘operating system virtualization’. Jeff Layton writes that “In this article, I want to highlight two approaches to using containers in HPC. The first approach is UberCloud, which was started as “the online community and marketplace where engineers and scientists discover, try, and buy Computing as a Service.” It is where scientific applications can be performed in the cloud and where customers can purchase compute cycles. The second approach is NERSC’s Shifter (and Singularity), a container system for HPC that converts images from Docker, VMs, or CHOS to a common container format.
