I have tried with a oob_tcp_if_include setting so that there is now only 1 interface. Even with just one interface and -mt=yes in both LDFLAGS and wrapper-ldflags I *still* getting messages like
[pcp-j-20:11470] mca_oob_tcp_accept: accept() failed: Error 0 (0). ------------------------------------------------------------ A process or daemon was unable to complete a TCP connection to another process: Local host: pcp-j-20 Remote host: 172.16.0.120 This is usually caused by a firewall on the remote host. Please check that any firewall (e.g., iptables) has been disabled and try again. ------------------------------------------------------------ I am getting less certain that my speculation about thread-safe libs is correct. -Paul On Mon, Dec 15, 2014 at 1:24 PM, Paul Hargrove <phhargr...@lbl.gov> wrote: > > A little more reading finds that... > > Docs says that one needs "-mt" without the "=yes". > That will work for both old and new compilers, where "-mt=yes" chokes > older ones. > > Also, man pages say "-mt" must come before "-lpthread" in the link command. > > -Paul > > On Mon, Dec 15, 2014 at 12:52 PM, Paul Hargrove <phhargr...@lbl.gov> > wrote: >> >> >> On Mon, Dec 15, 2014 at 5:35 AM, Ralph Castain <r...@open-mpi.org> wrote: >>> >>> 7.
