Indeed if I extract the -13 .debs and set LD_LIBRARY_PATH, mpqc spins at 100% without output. Even if I just run /usr/bin/ompi-ps without arguments, it eats 100% cpu and spins at sched_yield() forever accordings to strace: socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 7 setsockopt(7, SOL_TCP, TCP_NODELAY, [1], 4) = 0 setsockopt(7, SOL_SOCKET, SO_SNDBUF, [131072], 4) = 0 setsockopt(7, SOL_SOCKET, SO_RCVBUF, [131072], 4) = 0 fcntl64(7, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(7, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(7, {sa_family=AF_INET, sin_port=htons(37855), sin_addr=inet_addr("172.28.17.11")}, 16) = -1 EINPROGRESS (Operation now in progress) sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 [...] Reassigning to openmpi-bin for now, I am of course open to suggestions for any work-arounds or other things to try.
