# CreatePortableComputeGraph

Create portable compute graph from the supplied values.

Package: compute.graph | Status: source-declared

Describe compute work as an explicit graph with package-owned validation and scheduling metadata.

```yh
external CreatePortableComputeGraph(text name, list of portableGraphValue values, list of portableGraphNode nodes, list of text outputValues, bool eagerParityRequired) returns portableComputeGraph
```


## Use CreatePortableComputeGraph

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

Verification: type checked

```yh
using compute.graph

// Describe compute work as an explicit graph with package-owned validation and scheduling metadata.
text name = "Nova"
list of portableGraphValue values = []
list of portableGraphNode nodes = []
list of text outputValues = []
bool eagerParityRequired = true
portableComputeGraph result = CreatePortableComputeGraph(name, values, nodes, outputValues, eagerParityRequired)
Console.Log("Inspect result in your debugger")

```

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.graph--CreatePortableComputeGraph/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


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