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 <tdevries@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.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
