Hello, I am getting errors with building -with-device=ch3:nemesis:ib, using GNU, Intel or PGI compilers, as: I am wondering what's going on since this since Intel and GNU worked in version 3.1.2. I configure as: ../../../srcdir/mpich/3.1.4/configure --prefix=/uufs/chpc.utah.edu/sys/installdir/mpich/3.1.4 --enable-romio --with-file-system=nfs+ufs --with-mpe -with-device=ch3:nemesis:ib --enable-threads=runtime --enable-fast=all and use RHEL6.6 with stock gcc 4.4.7. When I reported a similar issue earlier, Pavan suggested to use MXM - I tried that and that seems to work, however, perhaps since we run relatively old OFED (stock RHEL6-like), which does not come with MXM, I used the one from the latest Mellanox HPC-X, and, I am not sure if that's the best idea since I see crashes related to communication at certain workloads - which I don't see with other MPIs or when using the ib netmod in MPICH. Would you please also mind commenting on this? Would you expect the just released 3.2b2 fare better with MXM than the 3.1.4?
