This R0 needs to be forwarded by some/all of the relevant SGs before going to LEWG for design review. Removing the LEWG label.

Mark, if you want some early design review, we can look at this in LEWGI.

Cologne 2019-07 LEWGI Minutes

P1673R0 & P1674R0 C++ BLAS Library: Design Feedback

Champion: Christian Trott

Minute Taker: Tobias Loew

Start Overview: 07-16 8:52

Start Review: 9:20

Algorithms are parameterized on a concept, iterators. The proposed linear algebra algorithms are parameterized on a concrete view type, mdspan.

Do people need to spell scaled_scalar? Can it just be an implementation-defined type with certain properties.

SG1 needs to review this from a parallelization/vectorization angle.

How should we handle outputs in the API?

Explore a range-style lazy view API.

End: 10:17

CONSENSUS: Bring a revision of P1673R0, exploring conceptification of mdspan and a range-style lazy API, to LEWGI for further design feedback.

This is informative, so not needed for additional LEWGI review.
