a) i faced the very same issue on my (sloooow) qemu emulated ppc64 vm b) i was able to run very basic programs when passing --mca coll ^ml to mpirun Cheers, Gilles On 2014/08/01 12:30, Ralph Castain wrote: > Yes, I fear this will require some effort to chase all the breakage down > given that (to my knowledge, at least) we lack PPC machines in the devel > group. > > > On Jul 31, 2014, at 5:46 PM, Paul Hargrove <phhargr...@lbl.gov> wrote: > >> 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.
