Parallel IR [PIR] --- Discussion sheet

Dear community,

as announced earlier we want to restart the discussion on a parallel IR
extension also with regards to the BoF at the US developers meeting.

An initial document containing preliminary requirements, common
problems, (some) existing approaches, etc. is available here:
  Parallel LLVM IR - Google Docs
It should be editable by anyone and also allow to comment the content.

I would kindly ask people interested in this topic to check out the
document and edit, comment or extend it. It is also possible to discuss
it on the mailing list. I will try to insert comments and discussion
results from the mailing list into document as well.

Thanks in advance,
