Add module="unique" to closure-defined @wp.kernel decorators in narrow_phase.py, contact_reduction_global.py, and sdf_contact.py. This prevents dynamically-created kernels from invalidating and forcing recompilation of their parent modules.

Before (robot_h1 cold-cache):

Module Compiles Total time
narrow_phase 2x (~15s each) 31,200 ms
contact_reduction_global 4x (~8-9s each) 35,890 ms
sdf_contact 1x 16,036 ms
Total 83,126 ms

After:

Module Compiles Total time
narrow_phase base + 3 unique 1x + 3 unique 3,469 ms
contact_reduction base + 2 2x + 2 unique 11,370 ms
sdf_contact (unique only) 1 unique kernel 16,092 ms
Total 30,931 ms

Net savings: ~52 seconds off cold-cache compile for these modules.

Newton Migration Guide

Please ensure the migration guide for warp.sim users is up-to-date with the changes made in this PR.

  • The migration guide in docs/migration.rst is up-to date

Before your PR is "Ready for review"

  • Necessary tests have been added and new examples are tested (see newton/tests/test_examples.py)
  • Documentation is up-to-date
  • Code passes formatting and linting checks with pre-commit run -a

Summary by CodeRabbit

  • Refactor
    • Updated internal kernel scoping across collision and contact processing (narrow-phase, SDF, and contact-reduction paths) to improve isolation and stability. No user-facing behavior, interfaces, or outputs were changed.

Add module="unique" to closure-defined @wp.kernel decorators in
narrow_phase.py, contact_reduction_global.py, and sdf_contact.py.
This prevents dynamically-created kernels from invalidating and
forcing recompilation of their parent modules.

Thanks a lot for improving this. The change looks good but for whatever reasons there are a ton of errors in the CI unit tests. Let me know if I should have a look.

@mmacklin maybe those failures are a warp issue that has been fixed recently - looks awfully similar to some failures we had in the MjWarp CI a few days ago. Updating to latest nightly warp would fix that issue, I think that's worth a try.

ok looks like it's not the same issue, unfortunately.

Thanks for taking a look guys - the CI failure appears to be due to a hashing bug with Warp related to unique modules. I have a fix in flight internally.

Will follow up once we have version of Warp with this change.

1298-1368: ⚠️ Potential issue | 🟡 Minor

Missing module="unique" on heightfield_triangle_contacts_kernel — inconsistent with the rest of the PR.

heightfield_triangle_contacts_kernel at Line 1301 is also a closure-defined kernel (inside create_heightfield_triangle_contacts_kernel), called at NarrowPhase.__init__ Line 1599 when has_heightfields=True. Without module="unique", this kernel will still invalidate and force a recompile of its parent Warp module on every instantiation, exactly the problem this PR aims to fix.

- Line 985: Add an explanatory comment on the wp.kernel decorator that clarifies
why module="unique" is required: note that create_compute_gjk_mpr_contacts is a
factory that generates a new `@wp.func` per call and those functions are wrapped
with wp.static() (see create_compute_gjk_mpr_contacts and the kernel using it),
which would change embedded-function hashes across sessions and force
recompilation; therefore module="unique" provides an independent module
namespace for each session to avoid invalidation.

1296-1300: heightfield_triangle_contacts_kernel is also a closure-defined kernel but is missing module="unique".

create_heightfield_triangle_contacts_kernel at Line 1296 follows the exact same closure pattern as the five updated factory functions: it captures writer_func and defines an inner @wp.kernel. For full consistency with this PR's optimization goal — preventing closure kernels from polluting the parent-module hash — this kernel should receive the same treatment.

(remove the module="unique" argument from the `@wp.kernel`(enable_backward=False,

the decorator as `@wp.kernel`(enable_backward=False), add a short comment
referencing GH-995 and that the change will be reinstated once the upstream Warp
fix is picked up, and block merging until CI passes with a Warp release
containing the GH-995 fix.

- Line 153: The decorator uses module="unique" for multiple closure-defined
kernels which triggers the upstream Warp GH-995 hashing bug; update each
`@wp.kernel`(enable_backward=False, module="unique") usage so the module name is
unique per kernel (e.g., module=f"unique_{kernel_name}" or include a numeric
suffix) or simply remove the explicit module argument to let Warp pick a safe
default; locate the five closure-defined kernels (the decorators at the shown
sites) and change their module strings to distinct identifiers (or drop the
module parameter) to avoid hash collisions.
