You might try also Piglit as it seems nowadays to have some support for Vulkan.
On quick browse I didn't see any test for compute with Vulkan though.

AFAIK Mesa CI runs both CTS and piglit, so getting the resulting test to
upstream version of either piglit or CTS would be good.

Sorry, I of course meant: "--with-vulkan-drivers=intel".

Every few days there's recoverable GPU hang on some SKL or BXT device in
GfxBench Manhattan 3.1, CarChase or AztecRuins.</pre>
