Hi Kristina,
Although its reported by cuda-memcheck as an error it really is an expected
return code from cuPointerGetAttributes. The CUDA-aware build of OpenMPI calls
cuPointerGetAttributes to query if a pointer is a host or device pointer.
Memory allocated with the system allocator (malloc, g
Hi Iman,
How are you handling GPU affinity? Are you using CUDA_VISIBLE_DEVICES for that?
If yes can you try using cudaSetDevice in your application instead?
Also when multiple processes are assigned to a single GPU are you using MPS and
what GPUs are your running this on?
Hope this Helps
Jiri

Hi,
Thanks for taking a look. I just learned from PGI that this is a known bug that
will be fixed in the 14.2 release (Februrary 2014).
Thanks

Hi,
I am trying to compile OpenMPI 1.7.3 with pgc++ (14.1) as C++ compiler. During
configure it fails with
checking if C and C++ are link compatible... no
The error from config.log is:
configure:18205: checking if C and C++ are link compatible
configure:18230: pgcc -c -DNDEBUG -fast conftest_
