Merge of PR #3066 on 7/6/2018 resulted in no Zoltan build errors and all 34 passing Zoltan tests on 7/7/2018.

Description

The Zoltan executable zCPPdrive fails to link in the CUDA 8.0 debug build Trilinos-atdm-white-ride-cuda-debug-pt-all-at-once run on 'white' and 'ride'. The link error output for the build this morning shown here on 'white' shows:

Steps to reproduce

This build error can reproduced on 'white' or 'ride' as described in the document:

• https://github.com/trilinos/Trilinos/blob/develop/cmake/std/atdm/README.md

The specific instructions for 'white' or 'ride' are given at:

• https://github.com/trilinos/Trilinos/blob/develop/cmake/std/atdm/README.md#ridewhite

The one difference is that this build of all of the Primary Tested Trilinos packages (that includes more package than are being used by ATDM APPs currently) does not exclude any Trilinos packages so it uses the file Trilinos/cmake/std/atdm/ATDMDevEnvSettings.cmake instead of the file ATDMDevEnv.cmake.

After cloning Trilinos, the following commands should reproduce the build failure:

$ cd <some_build_dir>/

$ source $TRILINOS_DIR/cmake/std/atdm/load-env.sh cuda-debug

$ cmake \
  -GNinja \
  -DTrilinos_CONFIGURE_OPTIONS_FILE:STRING=cmake/std/atdm/ATDMDevEnvSettings.cmake \
  -DTrilinos_ENABLE_TESTS=ON -DTrilinos_ENABLE_Zoltan=ON \
  $TRILINOS_DIR

$ make NP=16

I (@bartlettroscoe) just tired this on 'white' and I was able to reproduce the same build failure shown on CDash shown above.

These instructions worked perfectly. Thank you, @bartlettroscoe

With the merge of PR #3066 yesterday, this Zoltan build error is now gone as shown here. Note the -1 subscript by the 0 build errors for the Zoltan package.

Closing as complete.

Thanks for taking care of this @kddevin!
