MAGEEC

Welcome to the Wiki for the MAchine Guided Energy Efficient Compilation Project (MAGEEC).

This wiki uses the category system to group pages. The tabs above will take you to the main categories.

Getting Involved

Wiki

You can register for the wiki here. Please use the wiki category system with any new pages, since that makes the index more useful.

Standard Wikipedia formatting conventions apply here. Only the first letter of page names and section headings should be capitalized. Pages should only use heading level 2 and below.

Mailing lists

• The main mageec mailing list is mageec@mageec.org. Anyone can join, and this is where most work is discussed.
• The research team at Embecosm and Bristol University have an internal mailing list. Nothing especially secret here—just for issues it would be inappropriate to share with the entire community.

IRC

Day to day discussion is on channel #mageec at freenode.net. You can join by clicking here. The entire discussion is archived here.
