From 31ee519552f5e9991298f3b2cb6492d03fc6a266 Mon Sep 17 00:00:00 2001 From: Timo Heister Date: Tue, 15 Oct 2024 12:35:56 -0400 Subject: [PATCH] fix flaky trilinos/solver_control_06 Reading from the stdout file generated by the test runner seems to occasionally fail in parallel. Maybe it is okay to not check the output in that case... --- tests/trilinos/solver_control_06.cc | 24 ++++--- ...control_06.with_p4est=true.mpirun=2.output | 72 -------------------
