[mvapich-discuss] Error compiling MVAPICH2 with CUDA on Ubuntu Server

[José Manuel Molero]

Hi,

Thanks a lot!

This are the compilers version:

./mpich2version 
MVAPICH2 Version:         1.8
MVAPICH2 Release date:    Mon Apr 30 14:56:40 EDT 2012
MVAPICH2 Device:          ch3:mrail
MVAPICH2 configure:       --with-pm=no --with-pmi=slurm   --with-device=ch3:mrail --with-rdma=gen2 --enable-g=dbg --disable-fast --enable-cuda --with-cuda=/usr/local/cuda-5.0 MPICH2LIB_LIBS=-lm
MVAPICH2 CC:      gcc    -g
MVAPICH2 CXX:     c++   -g
MVAPICH2 F77:     gfortran   -g 
MVAPICH2 FC:      gfortran   -g

gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3


Now the make is completed with no errors using this configure

./configure --with-pm=no --with-pmi=slurm     --prefix=/home/jmolero2/mpi  --with-device=ch3:mrail  --with-rdma=gen2            --enable-g=dbg  --disable-fast --enable-cuda   --with-cuda=/usr/local/cuda-5.0   MPICH2LIB_LIBS=-lm   

I'm going to try an example.

Thanks.
