Bugs fixed in 5.0.0 release
Eclipse IDE for Parallel Application Developers
- Eclipse CDT - basics of C/C++ development
- plus the CDT UPC features
- PTP - Core features of PTP
- Photran - Development Environment for Fortran
- RDT, Remote Development Tools
- Some Linux Tools features not specific to Linux
- XML Editors and tools useful for creating new JAXB-based resource managers
- CVS and jGit
Note that not all of the features available in PTP are in this package. Features that provide PTP interfaces for other tools can be installed from the PTP update site, including:
- Tuning and Analysis Utilities (TAU)
- Graphical Explorer for MPI (GEM)
- Parallel Performance Wizard (PPW)
The PTP update site is already added in this package but must be enabled. See Updating from a previous release for information about updating.
PTP System Monitoring
The System Monitoring perspective provides scalable job and system monitoring for large-scale systems. It is based on the LLview monitoring system but has been extended to support monitoring of any type of system. It is currently only used for the PBS resource manager, but will be extended to other resource managers in the future.
PTP Resource Managers
Configurable (JAXB) Resource Managers
A new type of resource manager is available which makes it vastly easier to create and maintain new resource managers, without Java and Eclipse programming requirements. This configurable resource manager (also known from its implementation as a JAXB resource manager) defines a resource manager that can be configured from an XML file.
A detailed guide to the XML Schema, along with an introductory tutorial slide-set demonstrating some simple modifications to an existing XML definition, are available at PTP/resource-managers.
Remote Development Tools (RDT)
A new type of project is available, the synchronized project.
Synchronized projects consist of files that are mirrored on the local system as well as on one or more remote systems. Editing occurs locally and each file is synchronized with the currently active remote system when it is changed, created, or deleted. This enables faster interaction with the files and editor, more CDT editor features since the files are local, and continued interaction for editing etc. if the network connection is lost.
Parallel Language Development Tools (PLDT)
- Less intrusive/annoying insistence on setting MPI, OpenMP, preferences which were only used for non-prefix matching; more reliance on "prefix-only match" for artifacts, so these aren't really necessary now.
- More accurate location of artifacts including within macro expansions
Code templates make it easier to type common Fortran constructs. For example, by typing "pro", pressing Ctrl+Space, and then pressing Enter to choose the "program...end program" template, Photran will automatically fill in "program <name>" and "end program <name>" statements. As you type the program name, both the "program" and "end program" statements will be adjusted accordingly. Then, press the Enter key to begin filling in the body of the program.
"Correct Indentation" Command
Correct Indentation adjusts the indentation of the selected text in the editor (or the entire file if no text is selected). The current tab width (configured in the workspace preferences) is assumed to constitute one level of indentation.
Tabs-to-spaces conversion and custom tab width
It is now possible to set the "convert tabs to spaces" option in the Fortran editor without setting it workspace-wide. It is also possible to set a custom tab width for the Fortran editor.
New Horizontal Ruler
The Fortran editor has a new horizontal ruler. It looks a bit nicer, shows tab stops, and (unlike in previous versions) works in both the free- and fixed-form editors, even when folding is enabled.

External Tools Framework (ETFw)
Feedback view works on remote files
The ETFw Feedback view now works on files in a remote project. See Bug 349234 for a current limitation on remote DTD files.
Graphical Explorer of MPI Programs (GEM)
Full GEM help documentation can be found online here
GEM now supports remote C/C++ MPI projects whose connections are through one of the following remote service providers:
- Remote Tools
- Remote System Explorer
Target Machine Requirements:
- ISP version 0.3.0 or later
- Some implementation of MPI must be installed, MPICH2 or OpenMPI both work well
GEM Browser View
This highly functional view summarizes and categorically groups all of the errors and warnings found by GEM on a particular MPI verification run. The summary label (just above the tabs) gives the user a quick overview of problems found. Errors and warnings are mapped to the corresponding source code lines in the Eclipse editor. The Browser View's tabs help the user to quickly locate and fix MPI errors flagged by GEM in their source code. Full documentation for the GEM Browser View is here
Figure 1 below shows what the Browser View should look like along with an explanation of its components.
Browser View Tabs
Below the GEM Browser summary label (the line above the tabs summarizing the errors and warnings found) is a section containing a tab for category of error or warning that was found in the code. By selecting a particular tab the user is given detailed information on each occurrence of that type of error or warning in their MPI code. Clicking on any of these occurrences takes the user to the offending line in the source code within the Eclipse editor. If there are no instances of the problem then there is a short message indicating as much. Furthermore, a user is shown which types of errors are present via the icons of the tab (see icons directly below).
This tab allows the user to visit all of the calls that did not complete due to each detected deadlock.
This tab list all local assertion violations found. Clicking any one of these will take the user to the line of source code with the failed assertion.
Clicking any of these will take the user to the line of source code where the corresponding un-freed MPI resource was allocated (these are usually MPI communicators and MPI DataTypes).
This tab is reserved for Functionally Irrelevant Barriers. Clicking any these will take the user to the corresponding MPI_Barrier call itself, which can then be safely removed without changing the runtime behavior of the program. This could potentially speed the application up with the absence of unnecessary synchronization.
These are warnings about the send type not matching the receive type. In some cases this may be intentional, but often times it is a programming mistake.
New Preference Pages
GEM now has two preference pages. (Full documentation is here).
GEM Preference Page
This preference page is for settings related to how the views and various components within GEM behave and function. Here the user can control which GEM Views are shown and when, e.g. the active view (the view in focus after verification is complete), can be set on the GEM Preference Page. (see Figure 2 below).
ISP Preference Page
This preference page is for command line settings for the underlying formal verification engine GEM uses, In-situ Parital Order (ISP).
Additions include the following options (see Figure 3 below):
- Use Unix Sockets This dramatically increases the speed in which GEM verifies your application if run on a local machine.
- Host Where ISP Resides This will allow the use of GEM in a distributed setting
Enhanced Console Output
The main enhancement to this view is that during a GEM verification run, this view is active and gives STDOUT and STDERR as it occurs instead of a single lump sum at the end of the verification run. GEM console output is now red for STDERR. These enhancements help the user to recognize what is happening as the verification is being done at runtime (a status bar of sorts).
Parallel Performance Wizard (PPW)
New and Noteworthy for 5.0.5 release
PTP Developers, please add info here. Screen shots very welcome.
- ,  - Managed build projects using the Gnu toolchain were not consistently using module dependencies to determine build order
-  - PGI error parser did not recognize errors containing non-alphanumeric characters
-  - Opening/closing projects raised a ResourceException
-  - Managed build toolchains were selecting the deprecated Mach-O binary parser and Make error parser
-  - XL Fortran managed build toolchain was activating error parser with invalid ID
-  - Gnu managed build toolchain "Check syntax only (-fsyntax-only)" option in symbols was handled incorrectly
