9.1 Parallel System Support Programs (PSSP)
Program number- 5765 - D51
The PSSP software is a comprehensive suite of applications to manage an SP
systems as a full-function parallel processing system. It provides a single point of
control for administrative tasks and helps increase productivity by letting
administrators view, monitor, and control how the system operates. The PSSP
software is discussed in terms of functional entities called components of PSSP.
Most functions are base components of PSSP while others are optional; they
come with PSSP, but you choose whether to install and use them.
PSSP offers the following advantages:
򐂰 A full suite of system management applications with the unique functions
required to manage the RS/6000 SP system.
򐂰
Simplified installation, operation, and maintenance of all nodes in an RS/6000
SP system. You can operate from a single control workstation.
򐂰 Parallel system management tools for allocating SP resources across the
enterprise provided.
򐂰
Advanced performance monitoring for consolidated analysis and reporting.
򐂰 Error detection and recovery features that reduce the impact and occurrence
of unplanned outages.
򐂰 Coexistence is allowed for several releases within an SP partition allowing for
easier software migration.
9.1.1 Administration and operation
The PSSP system administration component packages make operating and
administering an SP system easy and efficient. This is accomplished through
tools and capabilities that PSSP offers.
Administrative features of PSSP:
򐂰 PSSP allows the system administrator/operator to perform all local and
remote administrative functions from the control workstation (CWS). This
makes the CWS a single point of control.
򐂰 It offers parallel system management functions across multiple SP nodes.
򐂰
PSSP contains the System Data Repository (SDR) for storing management
data that can be retrieved across the control workstation, file servers, and SP
nodes.
򐂰 It includes File collections for managing duplicated files and directories on
multiple nodes.
