[mvapich-discuss] Compiling MVAPICH2-1.9a on Host without IB

[sreeram potluri]

Jiri,

Support for communication from GPU memory is currently not available with
the OFA-IB-Nemesis interface. Can you try building with the OFA-IB-CH3
interface as below

./configure --with-device=ch3:mrail --with-rdma=gen2 --enable-cuda
--with-cuda=/usr/local/cuda-5.0 --enable-shared --prefix=<...>

or you can skip the device option as well as OFA-IB-CH3 is the default

./configure --enable-cuda --with-cuda=/usr/local/cuda-5.0 --enable-shared
--prefix=<...>

The following sections of the user guide might be useful

http://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.9a.html#x1-100004.4
http://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.9a.html#x1-140004.5

Let us know if you see any further issues.
