Thanks, this worked (build and install) I have yet to test it.
​​Is there a documentation on the values that can be used for --with-device and more details on enabling IB?

Hi Sylvain,

IB netmod is contributed by RIKEN and they are working on cleaning up this netmod. At the meantime, I would recommend using MXM netmod instead by specifying ??with-device=ch3:nemesis:mxm?. MXM is a netmod for IB networks using the MXM API instead of Verbs to interact with the HCA. Note that it is only for Mellanox hardware.

Thanks,
Xin

Subject: [mpich-discuss] Building mpich 1.3.4 w/ IB enabled

I downloaded mpich-1.3.4.tar.gz and was able to build it with GCC 4.9.1 and the following configure flags:

./configure \
 CC=/opt/gnu/gcc/bin/gcc \
 FC=/opt/gnu/gcc/bin/gfortran \
 CXX=/opt/gnu/gcc/bin/g++ \
 --enable-static \
 --with-device=ch3:nemesis \
 --with-thread-package=posix \
 --with-pm=hydra \
 --enable-shared \
 --enable-debuginfo \
 --prefix=$dest


If instead I try to build w/ IB support, namely:

./configure \
 CC=/opt/gnu/gcc/bin/gcc \
 FC=/opt/gnu/gcc/bin/gfortran \
 CXX=/opt/gnu/gcc/bin/g++ \
 --enable-static \
 --with-device=ch3:nemesis:ib \
 --with-thread-package=posix \
 --with-pm=hydra \
 --enable-shared \
 --enable-debuginfo \
 --prefix=$dest

I get the following (slew) of errors when building (make):

  Cheers,
    Sylvain
