How to reproduce:
-
Select AWS Ubuntu 17.04 instance ami-32e7464a on region us-west-2 on p3.2xlarge
-
Follow linux install guide.
-
Build examples
-
run device query = PASS
-
run device query again = CRASHES SERVER.
The first time any example kernel is launched CUDA works ok. Then subsequent launch crashes the server.
I have tried
- many images
- many regions,
- ubuntu 16.04 and 17.04
= install methods (deb/runtime etc).
And always the same result.
Amazon or Nvidia please fix! Been waiting weeks for this to work.
