Render fails with slice on GPU

[aroccaPrediqtt]

Hello,

I'm testing Ascent on an HPC cluster and I noticed that the execution fails when a pipeline is added to the actions

The same issue seems related to the previously reported issue:
#1119
which has been solved with an updated version of VTKm if I correctly understand

However, in my case the behavior is slightly different:

On my laptop, the same code runs without problems.

On the HPC cluster, the execution fails as soon as a pipeline is present.

This makes me suspect that on the laptop there may be some kind of fallback to host execution, while on the HPC system the pipeline tries to run fully on the device runtime and fails.

Minimal Example

The following works:

- action: add_scenes
  scenes:
    s1:
      plots:
        p1:
          type: pseudocolor
          field: velocity-x
          color_table:
            #name: "Rainbow Uniform"
            name: "Blue to Orange"

      renders:
        r1:
          # white background
          bg_color: [1.0, 1.0, 1.0]

          # black foreground (text, axes, etc.)
          fg_color: [0.0, 0.0, 0.0]

          # show the background color in the image (instead of transparent)
          render_bg: "true"

          # eliminate annotations (axes, legends, etc.)
          #annotations: "true"
          #world_annotations: "false"
          image_name: velocity-x
          # camera:
          #   azimuth: 0

But when adding a pipeline:

###############################################################################
# PIPELINE: SLICE Z
###############################################################################

- action: add_pipelines
  pipelines:
    slice_z:
      f1:
        type: slice
        params:
          point:
            x: 0
            y: 0
            z: 0.05    
          normal:
            x: 0
            y: 0
            z: 1

###############################################################################
# SCENE
###############################################################################

- action: add_scenes
  scenes:
    s1:
      plots:
        p1:
          type: pseudocolor
          field: velocity-x
          pipeline: slice_z
          color_table:
            name: "Rainbow Uniform"

      renders:
        r1:
          # white background
          bg_color: [1.0, 1.0, 1.0]

          # black foreground (text, axes, etc.)
          fg_color: [0.0, 0.0, 0.0]

          # show the background color in the image (instead of transparent)
          render_bg: "true"

          # eliminate annotations (axes, legends, etc.)
          annotations: "true"
          world_annotations: "false"
          image_name: slice_z

          camera:
            azimuth: 0

**the execution fails on the HPC system but not on the laptop (I guess the slice might be handle by Host?)
