򐂰 IBM Parallel Environment Developer Edition
Provides an integrated development environment (IDE) that combines open
source tools and IBM-developed tools to fulfill the following requirements:
– Editing, compiling, running, and debugging an application
– Performing static analysis of an application to find programming problems
– Analyzing the performance of serial and parallel applications
– Interactively running and debugging parallel applications
– Submitting batch serial or parallel jobs
IBM PE Developer Edition consists of two major integrated components:
– A client workbench that runs on a desktop or notebook computer
– A server that runs on select IBM Power Systems, IBM PureFlex Systems
servers, IBM System x systems, iDataPlex servers, and IBM NeXtScale
System
8.7.1 IBM Parallel Environment Runtime for x86
IBM Parallel Environment (PE) Runtime Edition is a capability-rich development
and run environment for parallel applications. IBM PE Runtime Edition offers
parallel application programming interfaces and run environment for parallel
applications.
Parallel Environment Runtime Edition includes the following components:
򐂰 The IBM Parallel Operating Environment (POE)
The IBM POE enables users to develop and run parallel applications across
multiple operating system images (nodes). POE includes parallel application
compile scripts for programs that are written in C, C++, and Fortran, and a
command-line interface (CLI) to submit commands and applications in
parallel. POE also provides an extensive set of options and other functions to
fine-tune the application environment to suit the running of the application and
system environment.
򐂰 IBM Message Passing Interface (IBM MPI)
The IBM MPI is a complete MPI 2.2 implementation, which is designed to
comply with the requirements of the MPI standard. IBM MPI supports the
MPI-2.1 process creation and management scheme. The IBM design is
enabled by using static resources that are allocated at job start time.
