Subject: [OMPI devel] Trunk broken for PPC64?
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2014-07-31 20:46:38


On the path to verifying George's atomics patch, I have started just by
verifying that I can still build the UNPATCHED trunk on each of the
platforms I listed.

I have tried two PPC64/Linux systems so far and am seeing the same problem
on both. Though I can pass "make check" both platforms SEGV on
   mpirun -mca btl sm,self -np 2 examples/ring_c

Is this the expected state of the trunk on big-endian systems?
I am thinking in particular of

If this big-endian failure is not known/expected let me know and I'll
provide details.
Since testing George's patch only requires "make check" I can proceed with
that regardless.
