To solve the undefined references to cudaMalloc and cudaFree, you need
to link the CUDA runtime. So you should replace -lcuda by -lcudart.
For the OPENCL undefined references, I don't know where those are coming
from ... could it be that hwloc is compiling OpenCL support but not
adding -lOpenCL to the mpicc command, thus causing this issue ?
To work around the issue, I would try to uninstall the opencl libraries
before recompiling Open MPI. Another way could be to add manually the
OpenCL library with -lOpenCL.

can you
./mpicc -showme -I/usr/local/cuda-8.0.61/lib64 -lcuda test_cuda_aware.c -o myapp
and double check -lcuda is *after* -lopen-pal ?

Nilesh,
Can you
configure --without-nvidia ...
And see if it helps ?
No, I need Nvidia cuda support.
Or else do you have a way to solve this open-cl errors?
./mpicc -I/usr/local/cuda-8.0.61/lib64 -lcuda test_cuda_aware.c -o myapp
./mpicc: /usr/local/cuda-8.0.61/lib64/libOpenCL.so.1: no version

Pointing to -L/usr/local/cuda-8.0.61/lib64 while compiling with mpicc
didn't help.
Any clues?
