miri-gpu SKILL.md skillA
miri-gpu from miri-lang/miri is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add miri-lang/miri/miri-gpu@git:20261014.6754659Pins git:20261014.6754659 in mdr.lock. Pin the fingerprint instead.

GPU kernels, forall loops, gpu fn, residency, and gpu frame blocks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GPU Programming in Miri
Miri compiles to GPU through the `forall` construct and `gpu` keyword. This skill teaches how to write GPU kernels, manage device memory, and interact with the GPU execution model.
## GPU Fundamentals
### Implicit Launch with `forall`
The simplest GPU pattern: declare a `gpu var` and iterate over it with `forall`:
```miri
use system.collections.array
const N = 1024
gpu var data = Array<f32, N>()
forall i in 0..N
data[i] = 2.0
```
Miri infers the grid dimensions from the range and array size.
### Multi-Dimensional Launches
`forall` supports 2-D and 3-D iteration. Literal bounds fold into the launch grid; runtime bounds use uniforms:
**2-D and 3-D launches (top-level only):**
Multi-dimensional `forall` is only valid at the top level, not inside `gpu frame` blocks. Use them to initialize buffers or set up geometry:
```miri
use system.collections.array
const W = 16
const H = 16
gpu var canvas = Array<int, 256>()
forall x, y in 0..W, 0..H
canvas[y * W + x] = x + y * 100
```
For 3-D:
```miri
use system.collections.array
const W = 8
const H = 8
const D = 4
gpu var volume = Array<f32, 256>()
forall x, y, z in 0..W, 0..H, 0..D

How to install
mdr add miri-lang/miri/miri-gpu@sha256:adfc67a76fe4ab4aThe line at the top of this page pins the label git:20261014.6754659, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
