Box 808, Livermore, CA 94551 This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344

2. Problem: –Provide high quality tools and customer support for SciDAC customers Solution: –Follow best in class software quality assurance (SQA) practices –Provide multiple mechanisms for customers to get customer support Impact –We have provided a mechanism for customer to get support in a manner that best suites them –We have SQA practices that ensure quality tools Problem: –Provide high quality tools and customer support for SciDAC customers Solution: –Follow best in class software quality assurance (SQA) practices –Provide multiple mechanisms for customers to get customer support Impact –We have provided a mechanism for customer to get support in a manner that best suites them –We have SQA practices that ensure quality tools www.vacet.org

3. VACET supports the VisIt user community E-mail lists at ORNL are supported by VACET personnel (visit-users, visit-developers, visit-help- scidac)

4. Visitusers.org provides documentation for users and developers User documentation –Basic information about using VisIt –Information about getting your data into VisIt –Sample python scripts Developer documentation –Software engineering practices –Design documentation –Development practices User documentation –Basic information about using VisIt –Information about getting your data into VisIt –Sample python scripts Developer documentation –Software engineering practices –Design documentation –Development practices www.vacet.org

5. VACET supports source code repository The VisIt SVN repository is provided by the SciDAC Outreach Center in combination with VACET

6. VisIt regression suite ensures new bugs don’t get introduced www.vacet.org Test suite is run nightly Run in 3 modes –Serial –Parallel –Scalable, parallel, icet Serial & parallel expect exact matches Scalable, parallel, icet allows an approximate match Ability to have mode specific test results Ability to skip tests Test suite is run nightly Run in 3 modes –Serial –Parallel –Scalable, parallel, icet Serial & parallel expect exact matches Scalable, parallel, icet allows an approximate match Ability to have mode specific test results Ability to skip tests

7. Regression suite allows multiple levels of drill down to easily find failures www.vacet.org

8. VACET is working on a continuous integration system that will continuously build and test VisIt It will test the building from scratch VisIt and all its third party libraries It will run the regression suite and post the results on a web page It will run on lots of platforms instead of just a narrow range of platforms as we do now It will test the building from scratch VisIt and all its third party libraries It will run the regression suite and post the results on a web page It will run on lots of platforms instead of just a narrow range of platforms as we do now www.vacet.org

9. VisIt Releases – Software Configuration Management Tag the release to create the release candidate (RC) Fixes for the release go on the RC RC changes get merged to the trunk When version ready we tag the release Bug fix releases come from the RC Tag the release to create the release candidate (RC) Fixes for the release go on the RC RC changes get merged to the trunk When version ready we tag the release Bug fix releases come from the RC www.vacet.org Trunk 012357 2.0RC 8 64911 1210 13 14 2.0RC 2.0.02.0.1

10. VisIt Releases – Steps to create a release Create the release candidate once the new features are complete Do the following concurrently until the code is ready to release: –Ensure our test suite passes in all 3 modes –Correct bugs on the release candidate –Build and test on our supported platforms –Gather release notes Build the binary distributions (automated scripts for many platforms) Release test the binary distributions Release the new version (update the web site, send out an e- mail announcement) Create the release candidate once the new features are complete Do the following concurrently until the code is ready to release: –Ensure our test suite passes in all 3 modes –Correct bugs on the release candidate –Build and test on our supported platforms –Gather release notes Build the binary distributions (automated scripts for many platforms) Release test the binary distributions Release the new version (update the web site, send out an e- mail announcement) www.vacet.org
