What is Lustre in HPC?

The Lustre file system is the ideal distributed, parallel file system for technical computing. Next generation storage built using Lustre software provides software-defined storage optimized to address the key storage and data throughput challenges of technical computing.

Who uses Lustre?

Deployments. Lustre is used by many of the TOP500 supercomputers and large multi-cluster sites. Six of the top 10 and more than 60 of the top 100 supercomputers use Lustre file systems.

What is Lustre computing?

Lustre is an open source parallel distributed file system (DFS) specialized for large-scale cluster computing. The name is a portmanteau of Linux and cluster.

Is Macos based on BSD?

Mac OS X is based on BSD UNIX, which is open source. Apple releases its open source fork of BSD as the Darwin operating system. The XNU kernel that Apple uses is its variant of the Mach kernel, which is an implementation of UNIX.

How does Lustre file system work?

Lustre is based on Linux and uses kernel based modules to achieve the expected performance. Lustre separates the metadata and the content of the files on different systems. Although this is not unique, the manner in which Lustre does this has proven highly efficient and reliable.

Where is Lustre file system used?

Lustre is used primarily for Linux based HPC clusters. Lustre is an open source file system and is licensed under the GPLv2. There are two main Lustre server components of a Lustre file system; Object Storage Servers (OSS) nodes and Meta Data Servers (MDS) nodes.

Is Lustre an object storage?

The Object Storage Servers (OSS) in a Lustre file system provide the bulk data storage for all file content. Files in Lustre are composed of one or more OST objects, in addition to the metadata inode stored on the MDS. …

Why should I use FreeBSD?

The main reason why we prefer FreeBSD over Linux is performance. FreeBSD feels significantly faster and more responsive than the several major Linux distros (including Red Hat Fedora, Gentoo, Debian, and Ubuntu) we’ve tested on the same hardware. Those are enough to make us choose FreeBSD over Linux.

Is macOS still based on FreeBSD?

You may have heard that Macintosh OSX is just Linux with a prettier interface. That’s not actually true. But OSX is built in part on an open source Unix derivative called FreeBSD. And until recently, FreeBSD’s co-founder Jordan Hubbard served as director of Unix technology at Apple.
