From: "tschwinge at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/99555] New: [OpenMP/nvptx] Execution-time hang for simple nested OpenMP 'target'/'parallel'/'task' constructs Date: Thu, 11 Mar 2021 16:36:39 +0000 [thread overview] Message-ID: <bug-99555-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99555 Bug ID: 99555 Summary: [OpenMP/nvptx] Execution-time hang for simple nested OpenMP 'target'/'parallel'/'task' constructs Product: gcc Version: 11.0 Status: UNCONFIRMED Keywords: openmp Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: tschwinge at gcc dot gnu.org CC: jakub at gcc dot gnu.org, kcy at codesourcery dot com, vries at gcc dot gnu.org Target Milestone: --- Target: nvptx Discovered during OpenMP 'task' 'detach' development. See PR98738, <http://mid.mail-archive.com/e7796b0a-c8ee-e695-3775-9edfa254c552@codesourcery.com>; when offloaded to nvptx, '-O0', the following hangs consistently: #pragma omp target #pragma omp parallel #pragma omp task ; This doesn't hang when offloaded to GCN or the host device, or if 'num_threads(1)' is specified on the 'parallel'. --- Not yet determined if this is a regression, when this started.
