#1426: Fatal loopcontrol assertion causes 23 test failures ----------------------+----------------------------------------------------- Reporter: hinder | Owner: eschnett Type: defect | Status: new Priority: critical | Milestone: Component: Carpet | Version: development version Keywords: | ----------------------+----------------------------------------------------- A recent change has caused 23 of the tests to start failing: https://build.barrywardell.net/job/EinsteinToolkit/786/testReport/

One of the error messages is:

{{{ /home/jenkins/workspace/EinsteinToolkit/arrangements/Carpet/LoopControl/src/loopcontrol.cc:795: void lc_control_init(lc_control_t*, lc_descr_t*, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t): Assertion `int(lc_fine_thread_comm.size()) < get_num_coarse_threads()' failed.cactus_sim: /home/jenkins/workspace/EinsteinToolkit/arrangements/Carpet/LoopControl/src/loopcontrol.cc:795: void lc_control_init(lc_control_t*, lc_descr_t*, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t): Assertion `int(lc_fine_thread_comm.size()) < get_num_coarse_threads()' failed. }}}

Many others are similar. I assume that this affects non-test runs as well. The test system has been offline since 6th August due to server maintenance, so the error was introduced sometime between 6th and 15th August.
