Bug ID: 113513
Summary: [OpenMP] libgomp: cuCtxGetDevice error with
OMP_DISPLAY_ENV=true OMP_TARGET_OFFLOAD="mandatory"
for libgomp.c/target-52.c
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: openmp, wrong-code
Severity: normal
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: jakub at gcc dot gnu.org, tschwinge at gcc dot gnu.org
Target Milestone: ---
When using both OMP_DISPLAY_ENV=true and OMP_TARGET_OFFLOAD="mandatory", the
device has to be initiated early as OMP_DEFAULT_DEVICE (either 0 or -4 =
omp_invalid_device) needs to be known before printing the ICVs.
On my system, this causes
libgomp: cuCtxGetDevice error: unknown cuda error.
That's with "CUDA Version: 12.3" and "NVIDIA RTX A1000 6GB" with
--with-arch=sm_80.
I am somewhat sure that I have manually tested it before; our tester wasn't
able to remotely set the env vars, hence, I don't know whether it did work
there or not - nor whether it is a regression, depends on CUDA, sm_xx, my card
or ...
