This isolation is useful for correcting an error condition or installing new
hardware and software without impacting production.

High Availability Control Workstation (HACWS) connects two RS/6000
workstations (with HACMP installed) to an SP system to provide a backup
control workstation in the event the primary one becomes unavailable (only
one is active at any time). A twin-tailed disk configuration, along with the IP
address takeover afforded by HACMP, enables rapid switch over to the
backup control workstation with little or no impact on operational access to
the SP system or System Data Repository.

The SP Resource Center provides one simple interface for all soft copy SP
documentation and information resources. It consists of HTML, Java, and
Java script files and works with a Web browser. The Resource Center
provides access to a variety of information including publications, READMEs,
Redbooks, white papers, product information, as well as up-to-date service
information.
򐂰 PSSP supports a multi-threaded, standards-compliant Message Passing
Interface (MPI) through an IBM Parallel Environment for AIX (PE) as well as
maintaining its single-threaded MPI support. In addition, PSSP includes a
Low-level Application Programming Interface (LAPI) with a flexible, active
message style, communications programming model on the SP Switch.
