# profileTrace

A profile trace record carrying label, shape, values, note.

Last updated: 2026-09-09

Package: compute.profiling | Status: source-declared

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

Collect and describe compute timing, work, and profiling records.

```yh
external thing profileTrace
```

- text label: Stores label as text.
- shapeTrace shape: Stores shape as shapeTrace.
- valueTrace values: Stores values as valueTrace.
- text note: Stores note as text.
- profileTrace(text label, shapeTrace shape, valueTrace values, text note): Profile trace.
- Describe() returns text: Describe.

## Use profileTrace

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

Verification: type checked

```yh
using compute.profiling

// Collect and describe compute timing, work, and profiling records.
profileTrace sample = profileTrace("Player health", shapeTrace("Player health", "origin", tensorShape("element Type", []), "note"), valueTrace("Player health", "origin", [], "note"), "note")
Console.Log(Text.From(sample.label))

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

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

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

[[dependencies]]
package = "console"

[[dependencies]]
package = "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.profiling--profileTrace/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## profileTrace.Describe

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

Verification: type checked

```yh
using compute.profiling

// Describe.
profileTrace instance = profileTrace("Player health", shapeTrace("Player health", "origin", tensorShape("element Type", []), "note"), valueTrace("Player health", "origin", [], "note"), "note")
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.
