Subject: [PATCH 0/4] openacc: Worker partitioning in the middle end
Date: Tue, 2 Mar 2021 04:20:10 -0800 [thread overview]
Message-ID: <cover.1614685766.git.julian@codesourcery.com> (raw)
This series contains updated parts of the patch series that was previously
sent upstream in November 2019:
https://gcc.gnu.org/pipermail/gcc-patches/2019-November/534547.html
The purpose of the series is to enable multiple workers for OpenACC
(workers being one of the dimensions of parallelism supported by the
standard) on targets such as AMD GCN. (NVPTX uses its own scheme for
supporting multiple workers, implemented mostly in the backend.)
Tested with offloading to AMD GCN and (separately) to NVPTX.
Further commentary is provided alongside individual patches. I'm posting
these patches for review now, but I don't expect to commit them until
stage 1.
Thanks,
Julian
