Subject: [OMPI devel] Errors during VampirTrace wrappers compilation, when used with CUDA 5
From: Dmitry N. Mikushin (maemarcus_at_[hidden])
Date: 2012-09-04 10:28:11


Oh, sorry, I did not realize this is actually a problem on VampirTrace
site! Then, I'm changing topic and forwarding this back to OpenMPI.

Thanks,
- D.
