General Trilinos Issues and Challenges

•What, in your mind, are the 2-3 top general issues facing Trilinos?– We will

• discuss things throughout the day• gather a list at the end of the day

New Make Targets• Proposed set of make targets:– make - Builds just the libraries– make install - Installs just the libraries– make clean - Cleans just the libraries and object files for the

libraries– make examples - Makes just the examples (assumes libraries

are built)– make install-examples - Install the examples (assumes libraries

are installed)– make clean-examples - Cleans just the examples (not the

libraries)– make tests - Makes just the tests (assumes libraries are built)– make clean-tests - Cleans just the tests (not the libraries)– make everything - Builds libraries, tests, and examples– make install-everything - Installs libraries and examples– make clean-everything - Cleans the tests, examples, and the

libraries

New process checklist ideas

•Adding a file to the repository?•Adding a test, example, etc?

•Other ideas– New checklists

– Revisions to current checklists

Release 7.0 Review

•What we want to improve for the next release– Installation testing– Tarball verification

• Automated testing/reporting• Can begin working on this before the freeze• Keep up with changes between releases

– Late entry decisions• Continue to handle case by case• Should try to avoid• Time is built in for unavoidable situations

– Timing – spring should be better than late summer– Other suggestions?

Page 12: Trilinos Framework: Next Steps

CVS vs SVN

• Should we switch to SVN?– Pros

• Directories, renames, and file meta-data are versioned• No part of a commit takes place until the

entire commit has succeeded• Revision numbers are per-commit, not per-

file (makes backing out changes easier)• Log messages are attached to the revision, not

stored redundantly• Efficient handling of binary files

Page 13: Trilinos Framework: Next Steps

CVS vs SVN

• Should we switch to SVN?– Pros (continued)

• Can use the Apache HTTP server to allow external access to the repository (no account necessary on server)• Directory specific write controls (also possible with

CVS, maybe easier with SVN???)

– Cons• Bonsai does not fully work with SVN yet

Page 14: Trilinos Framework: Next Steps

CVS vs SVN

• If we switch to SVN at some point– There are tools to convert a CVS repository to SVN

– We could experiment with SVN before converting

Customized Test Harness Runs

• If you would like any Trilinos branch to be tested periodically with a particular set of options, send those options to

[email protected]

• These tests will be run on the old Beowulf cluster at SJU

External Collaboration

• External package capability– Provides a simple way to plug a non-Trilinos

package into the Trilinos build system– See Trilinos/packages/external/README– External package must understand

• configure• make

– Minimal setup is required– Can take advantage

• Makefile.export• make runtests targets

Page 19: Trilinos Framework: Next Steps

External Collaboration

•What should we do for external packages that want some support (tools), but choose not to or cannot be a part of Trilinos? – Try to organize a common repository of “Trilinos

Compatible” code?• Sourcforge?• Should we try to test the code in any way?

– Leave them on their own?

Future framework development efforts

•Holes in current tools?•New tools?
