IBM PIOFS

Abstract

The IBM AIX Parallel I/O File System (PIOFS) allows fast parallel access to large temporary data files. Designed for the IBM RS/6000 SP, PIOFS is capable of scaling file input/output performance as the SP scales in compute performance. Implemented as an AIX Virtual File System, PIODS can coexist with other AIX files systems in both storage and compute nodes. Users may employ specific PIOFS functions to exceed the AIX 2 gigabyte file limitation, to create checkpointed versions of a file, and to define specific distributions of a data within a file. Through its use of multiple AIX-based server nodes, PIOFS eliminates the bottleneck caused by serial file server access.
