Hi,
On using openmpi from cygwin - I'm getting the following warning. Any idea how
to avoid this?
balay@ps5 ~
$ /usr/bin/mpiexec -n 1 hostname

[ps5:00491] [[23611,0],0] unable to open debugger attach fifo
The attempt to open a FIFO in the source file orte/orted/orted_submit.c:2862 is
failing due to a Cygwin bug. I think I see how to fix it. Stay tuned.
Sorry, I spoke too soon and was misinterpreting some code I was reading. I
don't see a Cygwin bug after all. Moreover, if I run your command under gdb, I
don't get an error.
Ken
I will look if the release candidate for 3.1.6 has still that issue.
3.1.5 had another larger warning that I silenced and that was due
to an upstream bug that has been solved.
This warning passed below my radar after I solved the bigger one.
Unfortunately OpenMPI takes age to build so do not expect any
too early..
Regards
Marco
