Hardware ...
IBM p575, POWER5, (Post-Production). Shared memory system. Four IBM p575
compute nodes each with 8 1.9GHz single-core POWER5 processors and 32GB of memory; an IBM p550 login node with
two 1.65GHz dual-core POWER5 processors and 8 GB memory; and 3TB shared scratch space available to all
five nodes using IBM's general parallel file system (gpfs).
Warranty for system expired December 2008.
System now running without warranty coverage, so hardware failures may
not be repaired.
Notes on using POWER5 system.

Mass Storage (Production) Dell/EMC Clariion CX700 storage (8TB usable), IBM DS3400 storage (12TB usable), and
IBM 3584 Tape Library containing 3592 tape drives and tapes. Tivoli Storage Manager with Space Management software is used to
provide hierarchical storage management. Older, larger files are migrated
from disk storage to tape. Migrated files are restored to disk automatically
if accessed. A backup copy of all files is also maintained on tape.
