And the FreeBSD backtraces again, this time configured with --enable-debug
and for all threads:
The 100%-cpu ring_c process:
(gdb) thread apply all where
Thread 2 (Thread 802007400 (LWP 182916/ring_c)):
#0 0x000800de7aac in sched_yield () from /lib/libc.so.7
#1 0x0008013c7a5a in
This case is not quite like my OpenBSD-5 report.
On FreeBSD-9 I *can* run singletons, but "-np 2" hangs.
The following hangs:
$ mpirun -np 2 examples/ring_c
The following complains about the "bogus" btl selection.
So this is not the same as my problem with OpenBSD-5:
$ mpirun -mca btl bogus -np
