Bug ID: 99932
Summary: OpenACC/nvptx offloading execution regressions
starting with CUDA 11.2-era Nvidia Driver 460.27.04
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: openacc
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: vries at gcc dot gnu.org
Target Milestone: ---
Target: nvptx
We're seeing OpenACC/nvptx offloading execution regressions (including a lot of
timeouts) starting with CUDA 11.2-era Nvidia Driver 460.27.04. Confirmed with:
CUDA 11.2-era 460.27.04, 460.32.03, 460.39, 460.56, 460.67, and CUDA 11.3-era
465.19.01, across several variants of GPU hardware.
Explicitly (re-)confirmed good are older versions such as CUDA 9.1-era 390.12,
and CUDA 11.1-era 455.38, 455.45.01.
Most of these are in the 'vector_length > 32' testcases, but also a few others.
