Hello,
I am also interested in working on polyhedral model guided auto-vectorization.
I went through the paper "Polyhedral-Model Guided Loop-Nest
Auto-Vectorization", that you suggested.
Does it use the GCC auto-vectorization algorithm to rewrite scalar
instructions into vector in
Hi,
Auto-Vectorization is still implemented in the 'old'- non polyhedral way.
Polyhedral model can only help drive the vectorization strategies.
What is happening is that Graphite (polyhedral model framework inside GCC)
is setting the flag on the loop that it thinks should be vectori
Hi,
Can anyone explain whether GCC has implemented Auto-Vectorization
based on Polyhedral Model?
Are there any related projects shooting at this, and in progress?
Steven.

the document the Omega library, PIP, PolyLib and PPL are mentioned.

Me:
I am from the LooPo group in Passau. We work since a long time on the
polyhedral model and would like to try some of our ideas in the gcc.
This will start summer 2009, as there is still some work left to make
graphite stable enough.
There are several other peo
Hi,
Thank you for helping me with those informations. From now on, I'll be
checking the Graphite framework, and I intend to contribute to that by
providing support to automatic parallelization. However, my project
focus on multicore architectures; I guess this is not a problem, is
it?
Thanks in a

Hi,
I'm a master degree student at University of Campinas
(Unicamp/Brazil), and I'd been trying to find a compiler to add to it
a loop optimization based on polyhedral model.
The polyhedral model (basically) works with nested loops structures,
performing some transformations, in order
