Hi Tim @maleadt  
I load julia via the following command

```julia
xxx@XXX:~$ julia7 -p 6
               _
   _ _ _(_)_ | A fresh approach to technical computing
  (_) | (_) (_) | Documentation: https://docs.julialang.org

  | | |_| | | | (_| | | Version 0.7.0-beta.0 (2018-06-24 01:32 UTC)
 _/ |\ __'_|_|_|\__'_| | Official http://julialang.org/ release
|__/ | x86_64-pc-linux-gnu

```

but failed to load CUDAnative then. I got an “unhandled task failure”. Do you know what that is?

I need CPU parallel computing for the pre-process, so I load julia program with the `-p 6` option.

Works here. Does it also crash by loading `CUDAdrv`? If so, please open an issue with more information for us to actually try and reproduce this (ie. platform details, exact package versions, etc).

Summary: probably an OOM situation, as indicated by the status returned by `cuInit` on Julia 0.6.  
The segfault on Julia 0.7 is unfortunate, but happens in CUDA so we can’t do much about that.  
Running with fewer processes fixed this particular issue.
