--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tom de Vries <vr...@gcc.gnu.org>: https://gcc.gnu.org/g:8570cce7c705f2ec3ffaeb8e47d58af22a075ebd commit r12-7814-g8570cce7c705f2ec3ffaeb8e47d58af22a075ebd Author: Tom de Vries <tdevr...@suse.de> Date: Fri Mar 25 10:06:41 2022 +0100 [libgomp, testsuite] Scale down some OpenACC test-cases When a display manager is running on an nvidia card, all CUDA kernel launches get a 5 seconds watchdog timer. Consequently, when running the libgomp testsuite with nvptx accelerator and GOMP_NVPTX_JIT=-O0 we run into a few FAILs like this: ... libgomp: cuStreamSynchronize error: the launch timed out and was terminated FAIL: libgomp.oacc-c/../libgomp.oacc-c-c++-common/parallel-dims.c \ -DACC_DEVICE_TYPE_nvidia=1 -DACC_MEM_SHARED=0 -foffload=nvptx-none -O0 \ execution test ... Fix this by scaling down the failing test-cases by default, and reverting to the original behaviour for GCC_TEST_RUN_EXPENSIVE=1. Tested on x86_64-linux with nvptx accelerator. libgomp/ChangeLog: 2022-03-25 Tom de Vries <tdevr...@suse.de> PR libgomp/105042 * testsuite/libgomp.oacc-c-c++-common/parallel-dims.c: Reduce execution time. * testsuite/libgomp.oacc-c-c++-common/vred2d-128.c: Same. * testsuite/libgomp.oacc-fortran/parallel-dims.f90: Same.
