Is there a jenkins way of testing on a different arch? (cross-compiling or going to a machine with a corresponding arch/OS)

[cmsbuild]

The tests are being triggered in jenkins.

Not yet. Once ROOT 6.04 or/and 6.06 becomes a default on CMSSW, then we will look into that. For POWER8 I am working on bootstrapping it, thus it has no RPMs yet in our repositories. I don't think there is a high number of POWER8 machines at CERN at this point also.

I found errors in the following unit tests:

---> test testDataFormatsPatCandidates had ERRORS
---> test runtestSimCalorimetryHGCalSimProducers had ERRORS

Failures not related as the change does not affect x86_64 in any way.

Comparison is ready

+1

for #12390 f7fd913

• changes affect only code compiled for PPC
• jenkins tests pass and comparisons show no differences as expected

unit test failures are present in the IB as well

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_0_X IBs (but tests are reportedly failing). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
