[cuCtxGetCurrent failed not initialized]
WARNING: The call to cuCtxGetCurrent() failed while attempting to register
internal memory with the CUDA environment.  The program will continue to run,
but the performance of GPU memory transfers may be reduced.  This failure
indicates that the CUDA environment is not yet initialized.  To eliminate
this warning, ensure that CUDA is initialized prior to calling MPI_Init.

NOTE: You can turn off this warning by setting the MCA parameter
      mpi_common_cuda_warning to 0.

[cuCtxGetCurrent returned NULL]
WARNING: The call to cuCtxGetCurrent() failed while attempting to register
internal memory with the CUDA environment.  The program will continue to run,
but the performance of GPU memory transfers may be reduced.  This failure
indicates that there is no CUDA context yet.  To eliminate this warning,
ensure that there is a CUDA context prior to calling MPI_Init.

[cuIpcGetMemHandle failed]
The call to cuIpcGetMemHandle failed. This means the GPU RDMA protocol
cannot be used.
  cuIpcGetMemHandle return value:   %d
  address: %p
Check the cuda.h file for what the return value means. Perhaps a reboot
of the node will clear the problem.

cannot be used.
  cuMemGetAddressRange return value:   %d
  address: %p
Check the cuda.h file for what the return value means. Perhaps a reboot
of the node will clear the problem.
#
[Out of cuEvent handles]
The library has exceeded its number of outstanding event handles.
For better performance, this number should be increased.
  Current maximum handles:   %4d
  Suggested new maximum:     %4d
Rerun with --mca mpi_common_cuda_event_max %d
#
[cuIpcOpenMemHandle failed]
The call to cuIpcOpenMemHandle failed. This is an unrecoverable error
and will cause the program to abort.
  cuIpcOpenMemHandle return value:   %d

Check the cuda.h file for what the return value means. Perhaps a reboot
of the node will clear the problem.
#
[cuIpcCloseMemHandle failed]
The call to cuIpcCloseMemHandle failed. This is a warning and the program 
will continue to run.

[dlopen disabled]
While trying to load the supporting libcuda.so library, an error was 
detected.  This error indicates that the Open MPI library was probably
configured with the --disable-dlopen flag.  When the library is 
configured in this way, CUDA support is disabled because CUDA support
depends on the ability to dynamically open libraries.  Reconfigure
without the --disable-dlopen flag to get around this problem.
#
[dladvise disabled]
While trying to initialize the lt_dladvise structure, an error was 
detected.  This error indicates that the Open MPI library was
configured such that there is no support for the lt_dladvise 
structure.  This is needed for properly opening the libcuda library.
Look around for the OPAL_HAVE_LTDL_ADVISE macro and ensure that it
is defined as a 1.  
#
[unknown ltdl error]
While attempting to load the supporting libcuda.so library, an error

MPI developers.
