An AFS-based supercomputing environment

The Pittsburgh Supercomputing Center (PSC) has been using the Andrew File System (AFS) to integrate its supercomputing environment. Work has been completed to make AFS the PSC's primary, permanent file-storage system. The PSC is using many of the components of this system in production. The PSC has extended AFS to meet its mass storage needs. These extensions include adding archival services to the AFS server and porting the AFS client to the Unicos operating system. The authors discuss the advantages of this system as well as how it performs in a supercomputing environment. >
