You are right, I have omitted the dyn libs. So, it is there

How is it there exactly?  Please send the nm output :)

hltaief@samsara:~/benchmarks/dpotrf$ nm -D /usr/local/cuda/lib64/libcudart.so.9.0 | grep MemcpyPeer

000000000003f510 T cudaMemcpyPeer

000000000004bdd0 T cudaMemcpyPeerAsync

There is no reason why we should use -lcudart_static.

That being said, I just dropped that detection, it can only pose problem
whenever NVidia does tricky things with the symbol, and nowadays we can
safely assume by default that it is available.

Not sure I followed you on this one.

Can you please explain?

Thanks
