Related Project: Eclipse Platform What is Eclipse?

In business-speak: “An open platform for tool integration built by an open community of tool providers”

In short: a framework for developing IDEs Sponsored by IBM and other commercial companies

Several IDEs based off of the Eclipse platform already exist Java IDE, C/C++ IDE, several others Much more functionality is also available through plugins to

the Eclipse platform Several new Eclipse-based projects are popping up

and the project’s structure itself is still evolving

Eclipse Platform Architecture

Eclipse idea: provide a basic framework as a starting point for other ideas

Framework contains such things as user interface elements (source code editor, etc) and basic project management facilities

Overall architecture shown right (taken from [1])

PTP Overview An extension to the Eclipse platform for writing, debugging,

and integration of existing parallel performance tools into the Eclipse IDE Uses existing Eclipse C/C++ development tool as a starting point Also supports Fortran development

Fortran IDE environment for Eclipse is available at http://www.eclipse.org/ptp/downloads.html

Incorporates an abstract interface for starting and monitoring parallel jobs as to support many different architectures

Main components C, C++, and Fortran IDE Parallel job launch utility Parallel debugger

Project Status Currently under development! Much work left to go before project will be in a usable state Summary of tasks (taken from PTP website) shown below (as

of 6/29/2005)

Description of task Status Owner

Parallel Runtime Model Design and implement a parallel model that will be used to represent a parallel machine/program.

Completed Nathan DeBardeleben

Parallel Runtime Views New views which provide efficient and scalable representation of parallel model.

In progress Nathan DeBardeleben

Parallel Runtime API Provide an API that can be used to interface to external parallel runtimes.

In progress Nathan DeBardeleben

Parallel Runtime API Implementation for OpenRTE Provide an implementation of the API that supports the Open MPI runtime.

In progress Nathan DeBardeleben

Parallel Runtime API Implementation for MPICH/ClustermaticProvide an implementation of the API that supports MPICH on a Clustermatic (bproc) machine

Assigned Nathan DeBardeleben

Parallel Runtime API Implementation for MPICHProvide an implementation of the API that supports MPICH out-of-the-box.

Project Status (2)Parallel Debug Model Extend CDT debug model to support parallel debugging.

Not yet assigned  

Parallel Debug Views New views which support parallel debugging requirements.

Not yet assigned

Parallel Debug API Provide a debug API that can be used to communicate with external parallel debug

controllers. The API will need to deal with issues specific to parallel debugging, such as managing groups of processes, handling large numbers of events, etc.

Not yet assigned  

Prototype Parallel Debug API Implementation Provide a prototype implementation of the parallel debug API that can be used for

testing/evaluations purposes. Not yet assigned  

Parallel Debug API Implementation For External Debuggers Provide implementations of the parallel debug API that support a range of external

parallel debuggers (e.g. idb, totalview).Not yet assigned  

Fortran Development Tools Develop an initial version of FDT. This will comprise a copy of CDT that has been

modified to add Fortran language support. Completed Craig Rasmussen 

Comman Language Support Identify and separate components of CDT that are language independent. Define

interfaces that will allow C and Fortran to utilize these comman language services.

In Progress  Craig Rasmussen

PTP General Comments The Eclipse IDE does provide a nice development environment and is

getting better every day The addition of a parallel development IDE is very nice Traditional development tools (make, emacs, vim, cvs, etc) can work well,

but IDEs do offer some advantages Being able to write, test, and debug code from within a single interface Better tool integration than what is possible with ad-hoc methods

Based on available documentation [2], PTP is geared towards initial development of parallel programs Focus on source code management, job launching, and parallel debugging No explicit hooks for parallel performance tools

If an IDE is desired for UPC and SHMEM development, PTP represents an ideal (only?) candidate However, still much work to be done on the project! Best to wait until project matures, then we can integrate our performance tool

with PTP if desired
