Figure 1-65 describes a Eight Declustered Array / Two Recovery Group configuration of a
Disk Enclosure. This configuration is referred to as fully populated. The configuration features
four SDDs (shown in dark blue in Figure 1-65) in the first recovery group and the four SSDs
(dark yellow in Figure 1-65) in the second recovery group.

1.9.7 IBM Parallel Environment
Parallel Environment is a high-function development and execution environment for parallel
applications (including distributed-memory and message-passing applications that run across
multiple nodes). This environment is designed to help organizations develop, test, debug,
tune, and run high-performance parallel applications that are written in C, C++, and Fortran
on Power Systems clusters. Parallel Environment also runs on AIX or Linux.
Parallel Environment includes the following components, as shown in Figure 1-66 on
page 89:
The Parallel Operating Environment (POE) for submitting and managing jobs.
The IBM MPI and LAPI libraries for communication between parallel tasks.
A parallel debugger (pdb) for debugging parallel programs.
IBM High Performance Computing Toolkit for analyzing performance of parallel and serial
applications.
