3. ESSL for AIX must be ordered separately.
4. The AIX product includes the C and math libraries in the Application Development
Toolkit.

2.4 Parallel Environment optimizations for Power 775

The parallel environment optimization for the Power 775 supports the HFI interconnect of the
IBM POWER7 processor-based server in User Space. IBM Parallel Environment Runtime
Edition 1.1 contains the following functional enhancements:
The IBM PE Runtime Edition is a new product, with new installation paths and support
structures. For more information, see Parallel Environment Runtime Edition for AIX V1.1:
Installation, SC23-6780.
Support for launching and managing multiple parallel dynamic subjobs by using a single
scheduler or resource management allocation of cluster resources.
A generic tool that is called Parallel Environment shell (PESH), which resembles a
distributed shell with advanced grouping and filtering. The tool is used for executing
commands on distributed nodes, and sending commands to, and collecting distributed
statistics from, running jobs. PESH also allows PNSD commands to run concurrently on
multiple nodes.
Enhanced scalability such that PE is now designed to run one million tasks per POE job.
Support for the HFI interconnect of the IBM POWER7 server in User Space.
