Concepts for READEX Tool Suite

A joint report describing the concepts for the integrated READEX Tool Suite. It includes the following parts that will be contributed by the leaders of the respective WPs: (1) A description of available tuning parameters (WP1), (2) The overall approach for scenario identification and the pre-computation of optimal platform configurations (WP2), (3) The architec-ture of the READEX Runtime Library (RRL) and the run-time scenario detection (WP3) (4) The concepts for the tool-suite integration (WP4)

Updated report on dissemination, communication, standardisation, and exploitation activities

This is an updated report of D6.3. This report will further document the final plans for short-term, mid-term and long-term exploitation and dis-semination of project results.

Future Parameters

A report describing system parameters that are available at the end of the project life-time in addition to the parameters described in D1.1. The re-port also contains an outlook on potential future parameters that would help the auto-tuning efforts.

Final description of the READEX Programming Paradigm

A report describing the final version of the new READEX Programming Paradigm that allow users to provide application-domain knowledge to the auto-tuning process, both to mark alternative code-paths and to support the detection and identification of scenarios at design-time and at run-time.

Second Periodic Report

This deliverable reports on the achieved results of the project and the overall schedule of tasks. It reports any deviations from the work plan and risks occurred with the performed work. It provides the final status of the REDEAX financials.

Report on application dynamism

A report describing and quantifying the different types of dynamic be-haviour found in the selected benchmarks and applications.

Initial report on dissemination, communication, standardisation, and exploitation activities

This initial report describes the participation in events for dissemination, communication, and exploitation. The report also provides a review of the main initiatives conducted by working groups and forums recognised as of interest from standardisation point of view. Possible participation in standardisation initiatives and related results, if any, will also be re-ported in this deliverable, together with any other results achieved by dissemination, communication, and exploitation activities.

Visualization of dynamism

Deliver the integration of the information on application dynamism dis-covered by PTF in Score-P to facilitate the visualization of dynamic behaviour / application phases in the Vampir trace visualization tool.

Report on external advisory board creation

A report describing the members of the External Advisory Board (EAB).

Analysis of tuning potential and scenario identification

The report will present the analysis strategy to predict the suitability of the application for the READEX tuning approach as well as the approach taken for scenario identification.

Final mechanisms for run-time detection, switching, and calibration

The final automatic mechanisms for inclusion in the RRL.

First Periodic Report

This deliverable reports on the achieved results of the project and the overall schedule of tasks. It reports any deviations from the work plan and risks associated with the performed work and planned milestones. It provides further a status of the READEX financial status and its budget spending.

Final RRL architecture

A report describing the principles for the scalable run-time library.

Dissemination plan

The dissemination plan has been established and is in operation

Final computation of configurations

Covers the final implementation of the design time computation of optimized system configurations.

Final tuning plugins

A set of tuning plugins for hardware, system-software and application parameters. Final version.

Evaluation of the READEX Tool Suite using the READEX test-suite

Final evaluation of the READEX Tool Suite using the READEX test-suite delivered in D5.2.

Final Report

This final report summarizes the project’s activities over its full duration. This report will cover the main aspects of the work, objectives, results and conclusions.

READEX Project Management Tools

An internal website will be created initially to form a repository of documentary and other information that is relevant to the implementation of the project, and that can also be used to provide an initial intra-project communication system. Additionally, the usual collaboration tools and procedures (e.g. mailing list, wiki, SVN) will be installed and made available to the project partners.

Enhanced READEX Public Website

The enhanced version of the project website will additionally contain the specific section targeted to the end users.

Initial READEX Public Website

The initial version of the website will contain the collaboration and communication tools and it will describe the vision of the project as well as the structure and role of the partners.

Final READEX Tool Suite

The final version of the integrated READEX Tool Suite to be publicly re-leased.

Prototype READEX Tool Suite

A prototype of the integrated READEX Tool Suite for first testing and validation

Hardware and system-software tuning plugins

A set of tuning plugins for hardware and system-software. Preliminary results for application parameters.

READEX Tool Suite version 2

A second version of the integrated READEX Tool Suite to be used for testing and validation.

Extended READEX test-suite with manually tuned applications

The READEX test-suite extended with manually tuned benchmarks and application to be used for comparison of productivity (required effort and achieved improvement in energy-efficiency) with the READEX Tool Suite.
