Subject: [PATCH 0/6] [og9] OpenACC worker partitioning in middle end (AMD GCN)
Date: Thu, 05 Sep 2019 01:46:00 -0000 [thread overview]
Message-ID: <cover.1567644180.git.julian@codesourcery.com> (raw)
This patch series provides support for worker partitioning in the middle
end. The OpenACC device-lowering pass (oaccdevlow) is split into three
passes: the first assigns parallelism levels to loops, the second (new)
part rewrites basic blocks to implement a neutering/broadcasting scheme
for the OpenACC worker-partitioned execution mode, and the third part
performs the rest of the previous device-lowering pass.
Also included are patches to add support for placing gang-private
variables in special memory (e.g. LDS, "local-data share", on AMD GCN),
and to rewrite reductions targeting reference variables to use temporary
local scalar variables instead.
Further commentary is provided alongside individual patches.
Tested with offloading to AMD GCN. I will apply to the
openacc-gcc-9-branch shortly.
Thanks,
Julian
