Grid Datafarm software architecture

What's Gfarm?

Gfarm is a reference implementation of the Grid Datafarm architecture designed for global petascale data-intensive computing. It provides Gfarm Grid file system that is a shared file system in cluster or Grid that can scale up to petascale storage, and realize scalable I/O bandwidth and scalable parallel processing.

Gfarm Grid File System

Gfarm Grid file system is a virtual file system that integrates local disks of compute/filesystem nodes. It consists of

many compute/filesystem nodes, and
Gfarm metadata server node.

On each compute/filesystem node, the Gfarm file system daemon (gfsd) is running to facilitate remote file operations with access control in the Gfarm filesystem as well as file replication, fast invocation, and node resource status monitoring.

Gfarm metadata server node manages Gfarm filesystem metadata and parallel process information, on which the Gfarm job manager (gfmd), and filesystem metadata server (postmaster or slapd) are running.
