So folks I have a job thats been running for the last 16 minutes on the sandbox (typically takes around 2 min). I see that it says Parallelism 
0
on the web ui. Am I missing something here ?
so it seems like it didn’t scheduled at all:

cc @Dan Rammer (hamersaw) @Radhakrishna Sanka - new PR's are merged and will be released soon, that gives you a lot more visibility. 1. scheduler states 2. timeline view
f
Seems like you don't have a node with enough CPU resources in your sandbox cluster...?
d
@Radhakrishna Sanka we have done quite a bit of work on task observability that will land in the next few weeks. Two things to highlight here: (1) 1.5 will have an updated status message in the task execution pane. So the information that "0/1 nodes are available: 1 Insufficient cpu ..." that you're seeing in k8s will be visible in the UI. In addition, we're planning on overlaying a time-series of these messages on the timeline view in the UI. Therefore, users can see the changing state of tasks during execution. (2) We have implemented the notion of "runtime metrics" from this RFC which will manifest to the user by breaking down the timeline view in the UI into more fine-grained information. Think things like workflow / node / task setup and teardown times, plugin-level overhead, etc. This will provide much better information into what is actually happening within a workflow execution.
To solve this problem, exactly what @Felix Ruess had mentioned. It looks like there is insufficient CPU to schedule the Pod.

Thanks @Felix Ruess @Dan Rammer (hamersaw). I’m gonna try spinning stuff down and seeing if I can get it to work. I think a key detail is that I do have a custom docker container.
f
That does not matter for the scheduler, only requested and available CPUs matter.
