Hi, I'm trying to build a pipeline that in principle it sounds like it
should be very simple. I basically have a project that I want to build
and test for Ubuntu trusty and xenial. So basically I want to run them
in separate nodes (which will use Docker).

I want to visualize this in blueocean like this:

  Checkout    Build     Test    Deploy

     O----------O--------O--------O
  trusty     trusty   trusty   trusty

     O----------O--------O--------O
  xenial     xenial   xenial   xenial

But I can't nail it. TL;DR, is there any way to achieve this? If yes,
how? If not, is it planned? If yes, any ETAs?

Things that I tried:

I can run 2 "jobs" in different nodes completely in parallel, but then
stages inside the nodes are not visualized:

parallel(
    'xenial': {
        node {
            stage("Setup") {
                sh 'echo xenial setup'
            }
            stage("Build") {
                sh 'echo xenial build'
            }
        }
    },
    'trusty': {
        node {
            stage("Setup") {
                sh 'echo trusty setup'
            }
            stage("Build") {
                sh 'echo trusty build'
             }
        }
    }
)

This shows:

    Parallel

        O
      xenial

        O
      trusty

If I add top-level stages outside of the node{}, then I get a closer
visualization, but then both track don't run completely in parallel:

stage ("Setup") {
    parallel (
        'xenial': {
            node {
                stage("Run") {
                    sh 'echo xenial setup'
                }
            }
        },
        'trusty': {
            node {
                stage("Run") {
                    sh 'echo trusty setup'
                }
            }
        }
    )
}
stage ("Build") {
    parallel (
        'xenial': {
            node {
                stage("Run") {
                    sh 'echo xenial build'
                }
            }
        },
        'trusty': {
            node {
                stage("Setup") {
                    sh 'echo trusty build'
                }
            }
        }
    )
}

And on top of not being really parallel, the synchronization points are
shown in the visualization (which makes sense if there are
synchronization points:

  Checkout         Build           Test          Deploy
     O-----.--.------O-----.-.------O-----.-.------O
  trusty   | |    trusty   | |   trusty   | |   trusty
           | |             | |            | |
     O----´   `-----O-----´   `-----O-----´ `------O
  xenial         xenial          xenial         xenial


So, questions again for the people that read this far :)
Is there any way to achieve this? If yes, how? If not, is it planned?
If yes, any ETAs?


Thanks a lot!
