High Performance Technical Computing Cluster - IBM RS/6000 SP Handbook

Parallel applications (applications are segmented to run in parallel and scale)
– High Performance Technical Computing (Message Passing Cluster)
• Extreme vertical scalability for a single large problem
• Mostly based on MPI (Message Passing Interface) standard
High Performance Interconnect

– High Performance Commercial Computing (Parallel Database Cluster)
• Extreme database scalability
• Shared nothing or shared disk
• Commercial "Parallel" databases (DB2 EEE, Informix XPS, Oracle
