Package: compute.device | Status: source-declared

Tags: compute, compute.device, cpu, device, method, source-example, thing, yeho

Inspect device capability catalogs and model resource lifetimes and placement decisions.

```yh
external thing computeRuntimeEvent
```

- int sequence: Stores sequence as int.
- int tick: Stores tick as int.
- text kind: Stores kind as text.
- text subject: Stores subject as text.
- int byteCount: Stores byte count as int.
- bool implicitSynchronization: Stores implicit synchronization as bool.
- text status: Stores status as text.
- text diagnostic: Stores diagnostic as text.
- computeRuntimeEvent(int sequence, int tick, text kind, text subject, int byteCount, bool implicitSynchronization, text status, text diagnostic): Compute runtime event.
- Describe() returns text: Describe.

## Use computeRuntimeEvent

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.device

// Inspect device capability catalogs and model resource lifetimes and placement decisions.
computeRuntimeEvent sample = computeRuntimeEvent(1, 1, "kind", "subject", 1, true, "ready", "diagnostic")
Console.Log(Text.From(sample.sequence))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_device__computeruntimeevent"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "compute.buffer"
version = "0.1.0"
path = "../../../yeho/packages/compute/buffer"

[[dependencies]]
package = "compute.device"
version = "0.1.0"
path = "../../../yeho/packages/compute/device"

[[dependencies]]
package = "compute.tensor"
version = "0.1.0"
path = "../../../yeho/packages/compute/tensor"

[[dependencies]]
package = "console"
version = "0.1.0"
path = "../../../yeho/packages/console"

[[dependencies]]
package = "diagnostics"
version = "0.1.0"
path = "../../../yeho/packages/diagnostics"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.device--computeRuntimeEvent/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## computeRuntimeEvent.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using compute.device

// Describe.
computeRuntimeEvent instance = computeRuntimeEvent(1, 1, "kind", "subject", 1, true, "ready", "diagnostic")
text result = instance.Describe()
Console.Log(Text.From(result))

```

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
